Applications
Manufacturers primarily consume PP DY-ZK0640P to extrude PPB (polypropylene block copolymer) pipes and mold associated pipe fittings. Cold water infrastructure requires materials that resist cracking under pressure and physical impact, especially during installation in cold environments. The specific Izod impact strength of ≥25 J/m at -20℃ ensures the extruded pipes will not shatter during winter handling or underground thermal shifts.
Extrusion lines require consistent melt flow to maintain uniform pipe wall thickness and prevent material degradation. The narrow MFR specification of 0.4±0.1 g/10min prevents surging in the extruder barrel, resulting in dimensionally stable cold water pipes. High tensile yield stress (≥20.0 MPa) guarantees the finished fittings can withstand continuous internal water pressure over long service lifespans.
Visual consistency matters for branded plumbing components and consumer-facing applications. Low yellow index values (≤4.0) ensure the final plastic components maintain a clean, consistent visual appearance. Strict limits on black speck particles prevent visual defects in the finished pipe surfaces.
Quality Control and Export Documentation
Industrial buyers require absolute certainty regarding material specifications before feeding resin into an extrusion line. BASTONE Petrochem eliminates sourcing risks by providing comprehensive technical documentation for every order. Clients can request the official Technical Data Sheet (TDS) and Safety Data Sheet (SDS) for PP DY-ZK0640P during the initial quotation phase.
Pre-shipment inspections verify that the packaging remains intact and the lot numbers match the factory-issued COA. PetroChina maintains strict appearance controls at the Dushanzi plant, limiting color and black speck particles to ≤10 pcs/kg. Our logistics team confirms these parameters align with your purchase order before authorizing container loading at the port of departure.
Consistent pellet quality prevents costly downtime and reduces scrap rates in downstream manufacturing. Off-size particles are strictly limited to ≤10 g/kg, ensuring smooth feeding through hopper systems and consistent melting in the extruder. BASTONE protects your production efficiency by delivering exactly what the specification sheet promises.
Why Source Through BASTONE
BASTONE Petrochem operates as an authorized distributor for China's top three petrochemical producers, including PetroChina and SINOPEC. Buyers purchasing KUNLUN brand resins through our platform receive full Certificate of Analysis (COA) documentation traceable directly to the Dushanzi production batches. Factory-direct allocations give our clients a distinct pricing advantage in the global market.
Procurement teams secure cost-effective supply chains without sacrificing material quality or documentation standards. Sourcing chemical raw materials internationally requires strict logistics control and adaptable trade terms. Zhejiang Bastone Technology Co., Ltd manages the entire export process, coordinating bulk container loading, customs clearance, and ocean freight.
We adapt packaging and shipping schedules to match your exact inventory requirements, ensuring continuous factory operations. Our parent company manufactures specialty chemicals and operates a dedicated R&D center in Hangzhou. Technical depth separates BASTONE from standard trading houses. When procurement managers face formulation adjustments or need to qualify alternative polymer grades, our supply chain specialists provide data-backed recommendations based on actual factory performance.
