Junyuan Petroleum Group manufactures cyclopentane/isopentane 50/50 blends in China and welcomes cooperation with industrial users, importers, distributors and trading partners throughout Brazil.
For buyers seeking direct communication with the manufacturer, our team is available to discuss product specifications, quality documentation, order quantities and shipment requirements. We welcome inquiries for both individual purchases and long-term supply programs, including requests for CFR Itapoá, Brazil.
Cyclopentane/Isopentane 50/50 for PU Foam Applications
Cyclopentane/isopentane 50/50 forms part of our cyclopentane/isopentane blends for PU rigid foam. Our product range includes this composition alongside other blend ratios, allowing customers to discuss their purchasing requirements directly with the manufacturer.
The starting point for each order is a clearly defined product specification. Please confirm whether your requested 50/50 ratio is expressed by weight or by volume, together with the permitted composition tolerances and other quality requirements.
| Item | Purchasing information |
|---|
| Product | Cyclopentane/Isopentane Blend |
| Nominal composition | Cyclopentane 50% / Isopentane 50% |
| Ratio basis | By weight or by volume, as agreed |
| Composition tolerances | According to the agreed specification |
| Quality requirements | Reviewed against the buyer’s purchasing specification |
| Bulk packaging | ISO tank |
| Destination | Itapoá or another Brazilian port, subject to shipment confirmation |
| Commercial terms | Quoted for the requested order and destination |
If your company already uses an approved formulation, send us your purchasing specification or a reference certificate of analysis with confidential details removed. This gives both teams a practical basis for discussing the required material.
Suitability for a particular formulation, production line or finished product should be evaluated and approved by the buyer.
Direct Communication with the Manufacturer
Junyuan Petroleum Group is a manufacturer and direct supplier of pentane products and blends. We welcome buyers who want to discuss their requirements directly with the production source while maintaining the purchasing structure that works for their business.
Our team can review inquiries covering:
- Blend composition and agreed tolerances.
- Quality parameters and test requirements.
- Technical specifications and supporting documents.
- Order quantities and purchasing schedules.
- Packaging and shipment arrangements.
- Documentation required for the transaction.
For buyers comparing cyclopentane/isopentane 50/50 manufacturers and suppliers, we welcome the opportunity to present our proposed specification and discuss how it aligns with their requirements.
We work with industrial purchasers as well as importers, distributors and trading companies serving Brazil. Direct industrial purchasing and commercial partnerships are both welcome.
A Clear Specification for Every Purchasing Program
An agreed specification creates a shared reference for quotation, order confirmation and quality acceptance.
Beyond the nominal 50/50 ratio, your purchasing requirements may include limits for water, sulfur, other components or additional parameters relevant to your process. Please identify the limits and test methods your company requires so our team can review them before confirming a proposal.
Useful documents for the initial discussion include:
- Your approved purchasing specification.
- A reference COA with confidential information removed.
- Required component ranges and ratio basis.
- Applicable test methods.
- Supplier qualification or document requirements.
Where a purchasing program involves repeat orders, the agreed specification should be referenced consistently in order documents. Any proposed changes can then be discussed against a clear technical baseline.
Quality Documentation and Supplier Review
Please tell us which documents your technical, quality and procurement teams need for evaluation.
These may include a proposed product specification, COA information, a Safety Data Sheet and company qualification materials. Our team will confirm the available documents and any order-specific requirements during the review.
The aim is to give your purchasing team a clear understanding of the proposed product and the agreed conditions before order confirmation.
Supply Planning Around Your Demand
A supply proposal should reflect how your company purchases and receives the material.
For a single order, please provide the quantity and preferred delivery window. For recurring demand, an estimated monthly or annual volume helps establish a starting point for discussing order sizes and shipment frequency.
To support planning, include:
- Estimated consumption.
- Preferred quantity per shipment.
- Expected order frequency.
- Desired shipment or arrival window.
- Destination port and final delivery city.
- Receiving-site requirements relevant to the delivery.
We welcome inquiries from Santa Catarina, Paraná, Rio Grande do Sul, São Paulo and other Brazilian states. Production schedules, shipment options and commercial terms will be reviewed for each proposed order.
CFR Itapoá, Brazil, and Other Destination Ports
Buyers requesting a quotation for Itapoá can identify their inquiry as:
Cyclopentane/Isopentane 50/50 — CFR Itapoá, Brazil
Please include the required specification, order quantity and preferred shipment window.
The quotation should clearly identify the agreed supply scope and the relevant commercial conditions. For ISO tank orders, this review should also cover tank free time, discharge scheduling and return arrangements, as applicable.
Provide the final delivery city as well as the port. This helps clarify the intended logistics arrangement and the responsibilities to be addressed in the transaction.
If another Brazilian port is preferred, include it in your request. Freight, routing and shipment feasibility are subject to confirmation, including carrier and terminal acceptance of the actual cargo.
