Meet demanding manufacturing requirements with this reliable durable polypropylene resin plastic, engineered to provide consistent material properties for diverse plastic production applications. The DALIANYOU T03 grade features a melt mass flow rate of 2.71 g/10min within the 2.5-3.5 specification range, ensuring optimal processing characteristics during injection molding and extrusion operations. This high-performance durable polypropylene resin plastic demonstrates excellent mechanical properties including tensile yield stress of 32.1 MPa and remarkable elongation at break of 481%, significantly exceeding the minimum 150% requirement for superior impact resistance and durability in finished products. Plastic manufacturers and product designers appreciate the consistent isotactic index of 97.1% that ensures uniform crystallization and the low ash content of 0.017% that maintains product purity while minimizing equipment wear during processing.

The material's technical specifications emphasize both processing efficiency and end-product performance. The balanced flow characteristics facilitate smooth mold filling while the exceptional elongation properties allow for the production of flexible yet durable components that withstand deformation and mechanical stress. This practical durable polypropylene resin plastic undergoes rigorous quality control with minimal colored granules (0 pcs/kg) and large/small granule variation (1 g/kg), ensuring consistent feeding and melting behavior in automated production systems. The combination of proven mechanical strength, processing stability, and consistent quality makes this durable polypropylene resin plastic particularly valuable for automotive components, household goods, packaging materials, and industrial parts manufacturers seeking material solutions that deliver reliable performance throughout the product lifecycle while maintaining cost-effective production efficiency.
