PP Orient Energy T30H Resin

Material Introduction: PP Orient Energy T30H is high‑flow homopolymer polypropylene, specially designed for high‑speed injection‑molding thin‑wall food containers and daily‑use articles. It meets food‑contact compliance such as GB 4806.6 with good cost‑performance, while its low‑temperature toughness is relatively weak.

Main Applications

Extruded flat yarn: woven bags, packing straps, ropes, carpet base fabrics.

Injection‑molding: household goods, toys and general daily‑use products.

Performance Parameters

Performance Category	Test Item	Test Condition	Reference Value	Unit	Reference Standard	Remarks & Interpretation
Basic Properties	Melt Flow Rate(MFR)	230℃/2.16 kg	2.5‑3.5	g/10 min	ASTM D1238	Homopolymer PP grade.
	Density	‑	0.90‑0.91	g/cm³	ASTM D1505	‑
Mechanical Properties	Tensile Yield Strength	‑	≥30‑32	MPa	ASTM D638	‑
	Flexural Modulus	‑	≥1100‑1200	MPa	ASTM D790	‑
	Izod Impact Strength	23℃	≥32‑39	J/m	ASTM D256	Room‑temperature impact.

Injection‑Molding Process Parameters

Process Item	Suggested Range / Description	Remarks
Drying treatment	Generally unnecessary; dry at 80℃ for about 1 h 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℃	‑
Melt temperature	‑	220‑280℃
Mold temperature	20‑70℃，recommended 40‑60℃	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 & complex parts, up to 180 MPa(1800 bar) except partial thin‑wall packaging containers.	‑
Holding pressure	30%‑60% of injection pressure	Prevent sink mark and excessive shrinkage; holding time accounts for approx. 30% of cycle time.
Back pressure	5‑20 MPa(50‑200 bar)	‑
Injection speed	Medium injection 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.
Runner & Gate	Pin‑point gate or multi‑point gate; heated hot‑runner, insulated hot‑runner. Gate shall be set at thick‑wall position of product, otherwise severe shrinkage defect easily occurs.	Mold‑design suggestion.
