PP Formosa Plastics 1024 Resin

Material Introduction: PP Formosa Plastics 1024 is homo‑polypropylene. It is characterized by high rigidity, high heat resistance and excellent transparency.

Main Applications

Transparent packaging & containers: bottles (especially blow‑molding), food‑contact containers.

Sheets & boards: transparent thermoforming sheets such as display boxes and file folders.

Daily & office supplies: plastic containers, kitchenware, furniture and office articles.

Performance Parameters

Performance Category	Test Item	Test Condition	Reference Value	Unit	Reference Standard	Remarks & Interpretation
Basic Properties	Density	‑	0.900‑0.910	g/cm³	ISO 1183	Typical homopolymer PP density.
	Melt Flow Rate(MFR)	230℃/2.16kg	1.8	g/10 min	ISO 1133	Low‑flow grade for blow‑molding & sheet extrusion.
	Molding Shrinkage	‑	1.3‑1.7	%	Internal method	Mold‑design reference.
Mechanical Properties	Tensile Yield Stress	‑	39.2	MPa	ISO 527‑2	High‑strength homopolymer.
	Elongation at Break	‑	200	%	ISO 527‑2	Good ductility.
	Flexural Modulus	‑	1570	MPa	ISO 178	High‑rigidity grade.
	Izod Notched Impact Strength	23℃	78 or 9	J/m or Kg·cm/cm	ISO 180	Unit dual‑recorded.
	Rockwell Hardness	R‑scale	110	‑	ISO 2039‑2	High‑hardness property.

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	30‑50℃ or 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.
Runner & Gate	Cold runner typical diameter:4‑7 mm. Gate diameter:1‑1.5 mm. Round gate & runner preferred. All gate types available, hot runner applicable.	Suitable for transparent part molding.
