Import C5 & C9 Copolymer Petroleum Resins — Buy in Bulk from Supplier in China

The C5 & C9 Copolymer Petroleum Resins offered by Laizhou Chiyuan Industry And Trade Co., Ltd are low‑molecular, thermoplastic polymers designed for compatibility with many polymeric compounds and thermoplastic elastomers. The supplier lists specific colour numbers (C9 colour No.9‑18, C5 colour No.5‑9) and softening point ranges such as 80‑90 °C, 100 ± 5 °C, 110 ± 5 °C, 120 ± 5 °C, 130 ± 5 °C and over 130 °C. Acid values are capped at 0.5 mg KOH g⁻¹, iodine values from 60‑120 g I₂ 100 g⁻¹ for C9 and 20‑120 g I₂ 100 g⁻¹ for C5, ash content not exceeding 0.1 % and a pH between 6 and 8. The product is supplied in 25 kg bags or as requested by the customer.

In the broader resin market, C5 and C9 copolymers typically exhibit softening points between 80 °C and 140 °C and acid values below 0.5 mg KOH g⁻¹, which match the figures provided by the supplier. Typical iodine values for C9 grades range from 60 to 120 g I₂ 100 g⁻¹, while C5 grades commonly fall between 20 and 120 g I₂ 100 g⁻¹, reflecting their level of unsaturation and adhesive potential. Standard bulk density for these resins is around 0.85‑0.95 g cm⁻³ and viscosity at 25 °C usually lies in the 150‑350 mPa·s range, values that buyers can use for process design. These typical specifications help compare performance across different manufacturers.

The resins find application in coating production, rubber treatment, adhesive manufacturing, printing inks, paper sizing agents and even oil‑field water treatment, making them attractive to paint formulators, tyre manufacturers, adhesive producers and paper mills. Suppliers often ship under FOB or CIF terms from Chinese ports, and custom packaging can be arranged to suit large‑scale production lines. As the listing does not state exact minimum order quantities, lead times or payment conditions, potential buyers should confirm these trade details directly with Laizhou Chiyuan Industry And Trade Co., Ltd.
