What is Cyclopentane?

The Oigin of Cyclopentane
A colorless, water-insoluble liquid, C5H10, obtained from petroleum and used chiefly as a solvent. Cyclopentane is a flammable liquid and its vapors can be explosive. Cyclopentane has a bond angle of about 108°C. This minimal ring strain for cyclopentane makes it a more stable compound.

Cyclopentane is in the class of cycloalkanes, being alkanes that have one or more carbon rings. It is formed by cracking cyclohexane in the presence of alumina at a high temperature and pressure.

Cyclopentane is a twisted ring in the form of an “envelope” so that one of the carbon atoms is out of the plane of the ring.

Cyclopentane is listed as a High Production Volume (HPV) chemical (65FR81686). Chemicals listed as HPV were produced in or imported into the U.S.

Cyclopentane is formed from pentane and is an alicyclic hydrocarbon compound that falls in the category of an alkane.

Cyclopentane is treated with chlorine in the presence of light or heat to form chloro cyclopentane which then reacts with KOC(CH3)3 forming cyclopentene. Cyclopentane has a bond angle of about 108o. This minimal ring strain for cyclopentane makes it a more stable compound. Besides, this compound occurs as a colourless liquid, and it is flammable. Moreover, it has a petrol-like odour. Cyclopentane is a simple hydrocarbon. If 0.0956 g of the compound is combusted in oxygen, 0.300 g of carbon dioxide and 0.123 g of water are produced.

Cyclopentane as a foaming agent and solvent used for insulation panels

Foaming technology of Cyclopentane polyurethane rigid PU foam

Cyclopentane, as a foaming agent and solvent, has brought many conveniences to our life. Cyclopentane can replace freon and be widely used in refrigerators, insulation materials for freezers and foaming agents for hard PU foam. It can also be used as a solvent for solution polymerization such as polyisoprene rubber and a solvent for cellulose ether. Cyclopentane, as a blowing agent in Polyurethane (PU) foams, is the most important raw material for high-performance insulation in refrigerators. It allows for a high energy efficiency, CO2 reduction and cost savings. At the same time, Cyclopentanes enable a particularly thin insulation for maximum volume utilisation.

Foaming technology is common in every refrigerator, and foaming materials are also very important, which are reflected in heat preservation, noise reduction, more constant box temperature and faster freezing time. There are only four kinds of foaming material technologies used in a refrigerator. The first is monochloroethane, which is the most primitive foaming process. Up to now, it can also be said to be a relatively backward foaming process. The thermal insulation performance of this foaming material is actually good. But there are two obvious shortcomings. One pollutes the atmosphere, the other is easy to crack. Therefore, internationally, the Montreal agreement clearly requires developed countries to completely ban it in 2010. Developing countries are allowed to use it until 2040. Our country has made it clear that the total phase out will be completed ten years ahead of schedule by 2030.

The second kind of Cyclopentane foaming, as a second-generation foaming technology, is used to replace monofluorodichloroethane, which is very good in environmental protection and is not easy to crack.

The third is 245fa mixed foaming agent, which initially aims to solve the problem of the lack of thermal insulation performance of cyclopentane foaming technology, and makes a balance between thermal insulation performance and environmental protection, which belongs to a transitional stage.

The fourth is HFO foaming agent, which is excellent in thermal insulation and environmental protection, and is not easy to crack. It is a luxury to use in refrigerators.

Cyclopentane is commonly used in household appliance foaming materials, and the GWP value of cyclopentane is very small. Halogen free, short life in the atmosphere, easy to decompose safely, and will not destroy the ozone layer. The thermal conductivity of gas phase is small. It can meet the technical requirements of most household appliances for thermal insulation performance.

Cyclopentane is flammable and explosive, with an explosion limit of (1.4-8.0)%. It is listed as a class a class B fire-fighting object in fire fighting. Cyclopentane is also a volatile organic compound, with a volatile amount of 8.5kg/m per hour, with a faint pungent smell. Therefore, there are strict requirements for production equipment, workshops, transportation and storage, as well as higher requirements for the quality and safety of enterprise employees.

Cyclopentane itself has low toxicity and deasterification function. Once it contacts the skin or splashes into the eyes, it should be immediately cleaned with clean water. Once cyclopentane leaks, it should be diluted and dispersed with inert gas nitrogen immediately. The above is the knowledge sharing on cyclopentane foaming process sorted out by Junyuan Petroleum Group and I hope it will be helpful to you!

Cyclopentane: a new blowing agent for polyurethane foam

Cyclopentane is used as a new blowing agent for rigid polyurethane foam. Now it has been widely used in fluorine-free refrigerator, freezer industry, cold storage, pipeline insulation and other fields. In the future, cyclopentane will become the leading role in the field of polyurethane blowing agent. Dongying Liangxin Petrochemical Technology Development Limited Company will tell you about the control points of cyclopentane in the foaming process.

  1. Strictly control the physical and chemical properties of stock solution
    The chemical properties of polyisocyanate, combined polyether, foaming agent, catalyst and foam stabilizer in black and white materials directly determine the chemical reaction of polyurethane synthesis and the physical properties of foam. It is the basic condition for producing qualified polyurethane foam.
    Black and white monomers shall be transparent viscous liquid without flocculent insoluble impurities. If there are insoluble impurities, the filter screen of the foaming machine will be blocked, resulting in unstable raw material flow, the ratio of black and white materials does not meet the requirements, and the mixture is uneven. Even the pipeline of the foaming machine is blocked.
    It is recommended to thoroughly clean the black and white material filter screens and needle valves of the foaming machine (and premixer) at least once a week.
  2. Strictly control the proportion and injection volume of stock solution
    The proportion of black material, combined polyether and cyclopentane must be strictly controlled. When the total injection volume remains the same, if the proportion of black material is too large, bubbles will appear, if the proportion of white material is too large, soft bubbles will appear, if the proportion of cyclopentane is too large, bubbles will appear, and if the proportion is too small, bubbles will appear. If the proportion of black and white materials is out of balance, the mixture will be uneven and the foam will shrink.
    The injection volume shall be subject to the process requirements. When the injection volume is lower than the process requirement, the foam molding density and strength will be low, and even the filling will not be dense. When the injection volume is higher than the process requirements, bubble expansion and bubble leakage will occur, and the box (door) will be deformed.
  3. Strictly control the process temperature and curing time
    Polyurethane foaming is a complex physical and chemical reaction process. The fluctuation of raw material, mold, preheating temperature and curing time will directly affect the foaming quality.
    A. Black material is a kind of active chemical substance, which is easy to react with water. During storage, the container shall be dry and sealed and filled with dry nitrogen for protection. It shall not be in direct contact with water during use. If the storage temperature is lower than 5 ℃, crystallization will occur, so attention must be paid to antifreeze. Once crystallization occurs, it shall be heated and melted at 70~80 ℃ before use, and fully stirred. When the storage temperature is higher than 50 ℃, an insoluble solid will be produced, the viscosity will increase and the chemical properties will change. White materials have the same properties.
    Therefore, black and white materials shall be stored in a ventilated, cool and dry place at room temperature (20~25 ℃) to avoid sun and rain.
    B. The black and white materials shall be subject to constant temperature treatment before foaming, and the foaming temperature shall be controlled at 18~25 ℃.
    When the temperature is too low, the black and white materials have high viscosity, unstable flow, poor fluidity and uneven mixing. When the temperature is too low, the reaction speed of forming foam is slow and the curing time is long. When the curing time is not enough, the box and door are still foaming after demoulding, resulting in appearance deformation.
    When the temperature is too high, the reaction is violent and difficult to control. It is easy to see that the performance of the foam injected into a large box is uneven. The foam injected at the beginning has undergone a chemical reaction, and the viscosity increases rapidly. The foam injected later has not yet reacted. As a result, the foam liquid injected later cannot push the foam liquid injected first to the front of the foaming process of the box, resulting in local cavitation in the box.
    C. The preheating furnace temperature shall be controlled at 30~50 ℃, the foaming furnace temperature shall be controlled at 35~50 ℃, and the foaming mold temperature shall be controlled at 35~45 ℃.
    The temperature of the box and door to be foamed in winter is low, so it must be preheated in the preheating furnace. Otherwise, when the hot polyurethane liquid contacts the box or door body, the chemical reaction will be seriously affected, and the foam liquid will not stick to the shell.
    When the temperature of the foaming mold is too low, the fluidity of the foaming solution system is poor, the curing time is long, the reaction is not complete, and cavitation occurs; When the temperature of the foaming mold is too high, the plastic liner is deformed by heating, and the foam system reacts violently. Therefore, the temperature of the foaming mold and the ambient temperature of the foaming furnace must be strictly controlled.
    Especially in winter, the foaming mold, preheating furnace, foaming furnace, box and door must be preheated for more than 30 minutes every morning when the line is opened. After a period of foaming in summer, the foaming system must be cooled.
    D. The foaming and curing time of black and white materials used by our company must be more than 6 minutes. The curing time is too short, and the box and door are still foaming after demoulding, resulting in appearance deformation. In particular, after the door body is deformed, the door seal gap is large when it is assembled with the box, the cold leakage occurs, the box is not insulated, and the compressor is frequently started.
  4. Strictly control the injection pressure of foaming machine at 13~16mpa
    When the injection pressure is unstable, the proportion of black and white materials is unstable and the mixing is insufficient. The injection pressure difference between black and white materials shall be controlled within 5bar, otherwise the foaming machine will be damaged due to material mixing.
    During the foaming process, the injection pressure of the foaming machine shall be checked frequently, and the injection system of the foaming machine shall be cleaned to avoid blocking.
    Black, white and cyclopentane are mixed unevenly, which is manifested by uneven density of polyurethane foam, local large bubbles, cracking of foam and local softening of foam: white, yellow or black stripes appear on foam, and foam shrinks.
  5. Preparation before foaming:
    A. Clean and inspect the mold. Before foaming, clean up the missing foam and other debris attached to the foaming mold, and check the mold fitting accuracy. Otherwise, serious quality problems such as damage to the box and bubble leakage will occur during foaming. Before foaming, check whether the exhaust and suction pipes of the box are well arranged as required and whether there are bends. Whether the outgoing line is complete and whether the drainage pipe has been installed. Whether the foaming process board is properly pasted according to the process requirements.
    B. Before door foaming, check whether the handle of the door body is installed correctly and whether it is inclined. Whether the wiring assembly dimension meets the process requirements. Whether the door lock is assembled as required. Whether the masking paper is pasted according to the process requirements and whether there is possibility of bubble leakage.
  6. Requirements for taking and placing box (door) body:
    The (door) body shall be handled vertically and gently, and no damage to the inner and outer boxes is allowed; The foamed box (door) shall be placed on the assembly line at uniform intervals. Then check whether the foaming quality meets the requirements. The leaking bubble shall be cleaned with tools, and the box (door) shall not be scratched.
  7. Foaming process control method
    1) Before each shift of production, it is necessary to check whether the parameters meet the process requirements. Check again every 3 hours and record the inspection results.
    2) Before each shift of production, the mixing condition and density of free foam must be tested. The mixing condition and density of the molded foam of the box body and the door body shall be tested once a shift. Then the free foam and molded foam were frozen at -20 ℃ for 24h, and their shrinkage was observed. The foam body shall have no obvious shrinkage. And record the inspection results.
    The above are the control points of cyclopentane in the foaming process. I hope it will help you. Please consult us for more questions about cyclopentane!
