PP Random Copolymer | >90% Transparency Food Grade MFI 1-30

Product Description

Product Description

PP resin injection molding(random copolymer) for crisper, petri dish, clear cup

Product Introduction

High-clarity random copolymer PP engineered for transparent injection molding applications. This low warpage resin delivers superior dimensional stability and meets stringent food contact PP compliance standards. And as a proven living hinge grade, it enables durable, flexible designs for consumer packaging and industrial components.

Basic Properties (ASTM Test Standards)

●Density: 0.90-0.91 g/cm³

●Melt Flow Index (MFI): 1-30 g/10min (230°C/2.16kg)

●Transparency: High (superior to homopolymer PP)

●Stiffness/Toughness Balance: Medium-high impact strength

Advanced Engineering Properties

●Low-Temperature Impact Resistance: Maintains toughness at -20°C (ideal for cold-environment parts)

●Chemical Resistance: Resistant to alcohols, acids/bases; avoid aromatics/chlorinated solvents

●Heat Deflection Temp (HDT): 90-110°C (0.45MPa)

●Dimensional Stability: Low shrinkage (±0.8-1.5%), reduces injection molding warpage
