Sinopec PPR-MT75

Sinopec PPR-MT75

Sinopec PPR-MT75 is a high-performance random copolymer polypropylene resin manufactured by Sinopec Zhongyuan Refinery[cite: 2]. Formulated with a random distribution of ethylene co-monomers along the polypropylene chain, PPR-MT75 delivers exceptional transparency, good heat resistance, and superior melt-flow processability designed specifically for injection molding applications[cite: 2]. It is particularly suited for high-speed production of thin-wall packaging and food containers[cite: 2].

Key Features

• High Transparency and clarity for premium product aesthetics[cite: 2].
• Good Heat Resistance for hot-fill and thermal exposure applications[cite: 2].
• High Flowability (MFR ~74.5 g/10min) for easy processing and fast cycle times[cite: 2].
• Balanced Mechanical Performance with high flexural modulus and good impact strength[cite: 2].
