High Clarity Grade 
High Clarity Grade 
RPP General Grade (PPR-MT45 Equivalent)
Sinopec / PetroChina Official Grade
RPP (Random Copolymer Polypropylene) is a premium material known for its exceptional transparency and gloss. Our General Grade, equivalent to Sinopec PPR-MT45, is highly optimized for high-speed injection molding. It offers a perfect balance of clarity, heat resistance, and impact strength, making it the top choice for medical devices and high-end housewares.
Key Advantages:
- Superior Transparency: Haze as low as 9%, comparable to glass.
- Odor-Free: Ideal for food contact and medical applications.
- Fast Cycle Times: High MFR (45) for efficient injection molding.
