Rubber-plastic composite materials
Rubber-plastic composites are high-performance polymer materials created by blending rubber and plastic through advanced physical blending or chemical cross-linking technologies. They perfectly combine the elasticity, flexibility, and sealing properties of rubber with the strength, rigidity, and ease of processing of plastic, creating a combination of properties unattainable by any single material. They are ideal for demanding working conditions and lightweight designs.

Key Product Highlights

· Synergistic Performance, Surpassing Single Material Performance

It combines the structural strength and creep resistance of plastic with the shock absorption, cushioning, and elastic recovery capabilities of rubber.

· Designable Performance: By adjusting the composition, ratio, and processing of rubber and plastic, the material's hardness, elastic modulus, oil resistance, and other indicators can be precisely controlled.

· Excellent Environmental Adaptability: Wide temperature range and media resistance (excellent resistance to oil, fuel, chemicals, ozone, and weathering).

· Convenient Processing, Doubled Efficiency: No vulcanization required, allowing for rapid molding through injection molding, extrusion, blow molding, and other methods, with extremely short production cycles and reusability.

· Lightweight and Long-Lasting Durability: Reduce weight and costs, and extend fatigue life.
