YUPLENE BX3920 is an automotive-grade propylene impact copolymer engineered to deliver exceptional impact strength, making it an ideal material for demanding auto parts applications. As a trusted supplier in the polymer industry, Suzhou Yifuhui New Material Co., Ltd. ensures that every batch of BX3920 meets the strict quality standards required by global automotive manufacturers. With our extensive experience in international trade and a strong supply chain network, we provide this high-performance copolymer to clients across North America, Europe, Southeast Asia, and beyond.
This product combines the rigidity of polypropylene with the toughness of elastomeric modifiers, resulting in excellent low-temperature impact resistance and dimensional stability. Whether you need durable bumpers, interior trim, or under-the-hood components, YUPLENE BX3920 offers reliable performance that reduces part failure and extends product lifespan. Its optimized molecular structure ensures consistent melt flow, enabling efficient injection molding and extrusion processes.
Key Features & Benefits
- Superior Impact Strength: With an Izod impact strength exceeding 500 J/m (notched) at room temperature, BX3920 withstands high stress and low-temperature impacts without cracking.
- Excellent Rigidity-Toughness Balance: Maintains high stiffness while providing outstanding flexibility, suitable for structural and aesthetic auto parts.
- Good Processability: Melt flow rate (MFR) of 2–10 g/10 min (customizable) ensures easy filling of complex molds and short cycle times.
- Thermal Stability: Withstands continuous use temperatures up to 85°C, with peak exposure up to 110°C.
- Chemical Resistance: Resists oils, greases, and common automotive fluids, reducing degradation over time.
- Low Warpage & Shrinkage: Designed for tight tolerances and consistent part dimensions.
- UV & Weather Resistance: Optional UV stabilizer packages available for exterior applications.
- Customizable Colors: Available in natural, black, or any RAL color upon request.
