PP Daxie Petrochemical 1102K Resin

Material Introduction: PP Daxie Petrochemical 1102K is spinning‑grade homopolymer polypropylene resin with high molecular weight and good melt strength.

Main Applications

Woven products: woven bags, bulk containers (FIBC), tarpaulins, color‑strip tarpaulins, carpet backing base fabrics and ropes.

Films: textile film yarns, packaging bags.

Injection‑molded products: mainly for extrusion processing, also applicable for small injection‑molded parts such as household gadgets and plastic bottle caps.

Injection‑Molding Process Parameters

Process Item	Suggested Range / Description	Remarks
Drying treatment	Generally unnecessary; dry at 80℃ for 1‑2 h under poor storage condition	‑
Barrel rear zone(feed section)	160‑180℃	Prevent thermal degradation.
Barrel middle zone(compression section)	180‑200℃	‑
Barrel front zone(metering section)	200‑220℃	‑
Nozzle temperature	200‑210℃	‑
Mold temperature	40‑60℃，recommended 50℃	Low temperature may result in poor surface quality, weld‑lines and flow‑marks; high temperature will cause warpage.
Injection pressure	70‑100 MPa	Higher pressure available for thin‑wall or complex‑structure parts.
Holding pressure	50%‑60% of injection pressure	Prevent shrinkage cavity and excessive shrinkage.
Injection speed	Medium speed	High‑speed injection improves appearance yet may induce internal stress; low‑speed injection benefits venting.
Screw speed	50‑100 rpm	Avoid excessive shear heat leading to material degradation.
