Import C5/C9 Copolymerized Petroleum Resin — Buy in wholesale FOB from Supplier in China

The C5/C9 copolymerized petroleum resin supplied by Liaocheng Kaiyue New Material Co., Ltd. is a low‑molecular‑weight thermoplastic resin with a molecular weight range of 300‑3000 g·mol⁻¹. It originates from the C5 and C9 fractions generated during petroleum cracking and is processed through pretreatment, polymerisation and distillation. The resin exhibits a low acid value and provides good miscibility with organic solvents, especially petroleum‑based solvents. Its chemical structure lacks polar groups, giving it strong resistance to water, ethanol, acids, alkalis, weathering and light ageing.

In the broader resin market, such copolymers are valued for their ability to modify viscosity and improve thermal stability of compound formulations. Typical grades of C5/C9 copolymer resin display a softening point between 90 °C and 150 °C and a colour ranging from pale amber to light brown. The material is compatible with a broad selection of thermoplastic polymers, rubber compounds and adhesive bases, allowing it to act as an accelerator, regulator or modifier rather than a standalone binder. Industry practice often blends the resin at 5‑20 % by weight to achieve the desired tack and cohesion in end products.

Applications include hot‑melt adhesives, pressure‑sensitive adhesives, synthetic rubber compounds, paints, rubber soles and radial tyre components. End users such as adhesive manufacturers, tyre producers and coating formulators benefit from the resin’s ability to enhance initial viscosity, adhesion between rubber particles and cord, and overall durability. Trade terms such as minimum order quantity, unit price and lead time are not disclosed in the listing and should be confirmed directly with the supplier. Potential buyers are advised to request a material safety data sheet and any relevant test certificates before placing an order.
