n-Pentane can be used to prepare isopentane and can also be used as extractant. Foaming agent of polystyrene, lubricant of liquid air. It is used for low temperature thermometers, making ice, anesthetics and synthesizing amyl alcohol. Isopentane is a mixture to improve the octane number of “lead-free” gasoline. It is also the raw material for isoprene production. Isopentene and isoprene can be prepared by dehydrogenation, and isoamyl alcohol can be obtained by chlorination and hydrolysis. When the content of n-Pentane in the product is more than 95% (WT), it can be used as the desorption agent of molecular sieve dewaxing process. The product can meet the requirements of different foaming degrees after blending with different proportions of isopentane. It can be used as an efficient foaming agent for expandable polystyrene.

Overall, in recent years, pentane demand shows a fluctuating growth state, with a slow growth rate. In 2021, the demand of China’s pentane industry is 363,000 tons, and the market scale reaches 1.96 billion yuan, of which the scale of Isopentane is the largest, accounting for 46%; n-Pentane is the second, accounting for 40%; Cyclopentane and other products account for 14%.

There are three isomers of pentane, namely n-pentane, isopentane and neopentane. The physical and chemical properties of the three substances are different, so they can be separated and purified by physical methods.

At present, the annual consumption of pentane in China is nearly 66 KT, of which the consumption of EPS pentane foaming agent is about 30 kt / A, accounting for 45% of the total consumption; the consumption of pentane for polyurethane is 33 kt / A, accounting for 50% of the total consumption; the consumption of pentane carrier solvent of linear low density polyethylene is 3 kt / A, accounting for 5% of the total consumption.

The market size of cyclopentane is estimated to be $242.4 million in 2018 and is expected to reach $335.7 million by 2023, with a compound annual growth rate of 6.7%. According to the in-depth study report on the global and Chinese Cyclopentane industry in 2018-2023 issued by New World industry research, the market growth can be attributed to the increased use of cyclopentane in residential and commercial refrigerator applications.

Isopentane is a mixture to improve the octane number of “lead-free” gasoline. It is also the raw material for isoprene production. Isopentene and isoprene can be prepared by dehydrogenation, and isoamyl alcohol can be obtained by chlorination and hydrolysis.

PROPERTIES

Polystyrene (PS) CAS No: 9003-53-6 Polystyrene (PS) is a thermoplastic resin with good processing properties. It is used in many applications including food packaging, domestic appliances, electronic goods, toys, household goods and furniture. The loss of growth in demand for PS has been a major challenge for the industry.
 Expandable Polystyrene (EPS) CAS No: 9003-53-6 Expandable polystyrene (EPS) is a rigid cellular form of polystyrene with good thermal insulation and shock absorbing properties, high compressive strength, very low weight and resistance to moisture.
PS (CAS no. 9003-53-6) is a polymer produced by the polymerization of styrene (CAS no. 100-42-5). There are other polymers in the PS family, such as expandable polystyrene (EPS), rubber-modified polystyrene or high-impact polystyrene (HIPS), which involve other monomers, such as 1,3-butadiene. 

Polystyrene (PS) is a clear, amorphous, nonpolar commodity thermoplastic that is easy to process and that can be easily converted into a large number of semi-finished products like foams, films, and sheets. It is one of the largest volume commodity plastic, comprising approximately seven percent of the total thermoplastic market¹. PS is a very good electrical insulator, has excellent optical clarity due to the lack of crystallinity, and has good chemical resistance to diluted acids and bases. It is also easy to fabricate into a large number of finished goods since it is a viscous liquid above its glass transition temperature (Tg) that can be easily molded. However, polystyrene has several limitations. It is attacked by hydrocarbon solvents, has poor oxygen and UV resistance, and is rather brittle, i.e. it has poor impact strength due to the stiffness of the polymer backbone. Furthermore, its upper temperature limit for continual use is rather low due to the lack of crystallinity and its low glass transition temperature of about Tg = 373 K (100°C). Below its Tg, it has medium to high tensile strength (35 – 55 MPa) but low impact strength (15 – 20 J/m). Despite all these weaknesses, styrene polymers are very attractive large-volume commodity plastics.

Some of its weaknesses can be overcome by copolymerization with other monomers. For example, polystyrene can be copolymerized with methyl methacrylate. The copolymer poly(styrene-co-methyl methacrylate) (PSMMA) has higher clarity and improved chemical and UV stability.

One of the most important styrene copolymers is poly(styrene-co-acrylonitrile) (PSAN). It has much improved chemical resistance, better heat stability, and improved mechanical properties. However, these copolymers often yield yellow products.

Probably of equal importance are poly(styrene-co-butadiene) (SBR, SBS) and poly(styrene-co-acrylonitrile-co-butadiene) (ABS). Both copolymers have very high stress and impact resistance and ABS has higher tensile strength than pure PS.

To increase the heat resistance, styrene is sometimes copolymerized with small amounts of maleic anhydride or it is copolymerized with this monomer to an alternating structure. The copolymer poly(styrene-co-maleic anhydride) (PSMA) has a higher Tg than pure polystyrene (400 – 430 K), improved heat resistance and high dimensional stability.

Many styrene derivatives have been synthesized on a laboratory scale and some have been extensively investigated. However, no other styrene polymer has become a large-volume commodity thermoplastic. Among those that are commercially produced are α-methylstyrene, o-, m-, and p-methylstyrene, methoxystyrene, chlorostyrene, divinylbenzene and p-divinylbenzene. The later is used as a cross-linking agent in a large number of different polymer materials.

Polystyrene is a not biodegradable plastic and resistant to photolysis. It is a major contributor to the debris in the ocean. Although recycable, polystyrene is not recycled in many parts of the world. The biggest problem is expandable polystyrene (EPS); due to its low density, it takes up a relative large amount of space in landfills.
In recent years, the (food) packaging industry has developed alternative insulating plastics for thermal applications, like Versalite which is an expanded polypropylene (PP) that can be recycled right along with other PP products in the general recycle stream. We expect other lower-cost and lower-density resins to gain market share in traditional large volume applications of expandable polystyrene.

COMMERCIAL POLYSTYRENES

Polystyrene is one of the most important commodity plastics. The production volume of polystyrene and styrene copolymers is several million tons per year. It is sold under various trade names, including Styrofoam™, Styropor^®, and Styron™

The three most important grades of styrene are:

GPPS: General purpose polystyrene, also known as crystal-clear polystyrene, is a fully transparent, rigid and rather brittle low cost thermoplastic made from styrene monomer. GPPS is a solid product manufactured in the form of 2-5 mm pellets.

HIPS: High impact polystyrene contains usually 5 to 10% rubber (butadiene) and is used for parts which require high(er) impact resistance. HIPS is a graft copolymer having polystyrene sidearms. The grafting occurs when some of the radicals react with the double bonds of the polybutadiene.

EPS: Expandable polystyrene consists of micro-pellets or beads containing a blowing agent (usually pentane). The expanded or foamed polystyrene is thermally insulating, has high impact resistance and good processability.

Styrenic Copolymers and their blends are considered engineering thermoplastics because their properties can be tailored over a wide range for a large number of applications with a broad range of processing methods which permits the manufacture of high quality, very durable plastic products suitable for many demanding applications.

APPLICATIONS

Polystyrene is a polymer that is cheap and easy to process. It is the material of choice for many applications including food-packaging, disposable consumer plastic goods as well as parts for optical, electronic/electrical, and medical applications. A large variety of products are formed by injection molding including dining utensils, plastic cups, housewares, toys, CD cases, cosmetic containers, covers and fixtures.

Expandable polystyrene, either crystal polystyrene² or styrene copolymers soaked with a blowing agent (usually pentane), are used to produce various foamed products, like disposable drinking cups, egg cartons, trays, fast-food containers, cushioned packaging, and thermal insulation for the construction market.

Medical applications include pipettes, Petri dishes and medicine containers.

Pentane is a straight chain alkane consisting of 5 carbon atoms. It has a role as a non-polar solvent and a refrigerant. It is a volatile organic compound and an alkane.
Pentane is an organic compound with the formula C 5 H 12 — that is, an alkane with five carbon atoms. The term may refer to any of three structural isomers, or to a mixture of them: in the IUPAC nomenclature, however, pentane means exclusively the n -pentane isomer; the other two being called “methylbutane” and “dimethylpropane“.
