Material Introduction: PP Orient Energy PPH‑Y26 is fiber‑grade homopolymer polypropylene. Mainly applied for fiber products according to industry common knowledge.

Main Applications

Fiber & non‑woven fabrics: polypropylene filament, long fiber, short fiber, non‑woven fabrics for medical hygiene materials and household articles.

Home textiles: fiber products such as garments and blankets.

Other applications: injection‑molded articles including household utensils and thin‑wall products.

Performance Parameters

Performance Category	Test Item	Test Condition	Reference Value	Unit	Reference Standard	Remarks & Interpretation
Basic Properties	Melt Flow Rate(MFR)	230℃/2.16kg	25‑26	g/10 min	ASTM D1238, ISO 1133	High‑flow fiber‑spinning homopolymer PP.
	Density	‑	0.90‑0.91	g/cm³	ASTM D792, ISO 1183	Typical PP density range.
Mechanical Properties	Tensile Yield Strength	‑	≥34.5	MPa	ASTM D638, ISO 527	High tensile strength for fiber spinning.
	Flexural Modulus	‑	≥1470	MPa	ASTM D790, ISO 178	High‑rigidity grade.
	Elongation at Break	‑	＞200	%	ASTM D638, ISO 527	Good ductility.
Thermal Properties	Heat‑Distortion Temperature(HDT)	0.45 MPa, non‑annealed	≥100	℃	ASTM D648, ISO 75	Heat‑resistance reference.
Other Properties	Isotactic Index	‑	≥96	%	‑	High isotacticity for fiber processing.

Injection‑Molding Process Parameters

Process Item	Suggested Range / Description	Remarks
Drying treatment	Generally unnecessary; dry at 80℃ for 1‑2 h if damp under poor storage condition	PP low‑moisture‑absorption feature.
Barrel rear zone(feed section)	160‑200℃	Prevent thermal degradation.
Barrel middle zone(compression section)	180‑220℃	‑
Barrel front zone(metering section)	200‑240℃	‑
Nozzle temperature	200‑240℃	‑
Mold temperature	40‑80℃, recommended 50℃	Crystallization mainly determined by mold temperature. Low temperature: poor surface, weld‑line and flow‑mark risks; high temperature will cause warpage.
Injection pressure	80‑140 MPa(800‑1400 bar)	Higher pressure for thin‑wall or complex‑structure parts.
Holding pressure	30%‑60% of injection pressure	Prevent sink mark and excessive shrinkage; holding time accounts for ~30% of cycle time.
Injection speed	Medium speed; high‑speed injection required for thin‑wall packaging containers.	‑
Screw speed	High screw speed(linear velocity 1.3 m/s) is permitted	Complete plasticization before cooling phase finishes.
