Import Cpvc — Buy in Bulk from Supplier in China

Cpvc resin from Gansu Jinshi Chemical Co., Ltd. is a chlorinated polyvinyl chloride compound with a chlorine content typically between 63% and 69%, enhancing thermal and chemical resistance beyond standard PVC. The material is supplied as a fine white powder, suitable for extrusion and injection molding processes used in pipe and fitting manufacturing. Its Vicat softening temperature exceeds 95°C, and it maintains structural integrity under continuous pressure up to 10 bar at 60°C, meeting ASTM D1784 Class 12454 and ISO 15874 standards for hot water systems.

The resin is formulated without lead-based stabilizers and complies with RoHS directives for heavy metal limits. Typical additives include impact modifiers, lubricants, and thermal stabilizers to improve processability and long-term durability. While the listing does not specify exact melt flow index or bulk density, industry-standard Cpvc grades for piping have an MFI of 3 to 7 g/10min at 200°C and bulk density between 0.5 and 0.6 g/cm³. These values are typical for injection-grade Cpvc used in pressure-rated systems.

This material is primarily sourced by manufacturers of hot and cold water distribution systems, fire sprinkler networks, and chemical processing pipelines. Buyers typically require consistent batch-to-batch performance for extrusion lines and require material certification for compliance with local plumbing codes. Packaging is usually in 25 kg multi-wall paper bags with inner polyethylene lining. Trade terms are FOB China port, with minimum order quantities typically negotiated per shipment volume, and lead times range from 20 to 30 days after deposit confirmation.

Gansu Jinshi Chemical Co., Ltd. is a manufacturer based in the Liuba-High And New-Tech Development Area, Zhangye, Gansu Province, China. The supplier is verified as an importer and exporter through harbor-level trade records, indicating active participation in international chemical trade. The listing confirms production capability but provides no details on factory size, workforce, or years in operation. No certifications, client lists, or production volumes are disclosed.

The company does not publish technical data sheets, quality control protocols, or third-party audit reports. While its location in a designated high-tech zone suggests industrial capacity, buyers must request material test reports and batch certificates directly before placing orders. The absence of response rate or average reply time indicates limited buyer communication infrastructure, making direct technical verification essential.
