Product Description
Thermoplastic Vulcanizate (e.g., EPDM/PP based) produced via dynamic vulcanization, combining the elasticity of rubber with the processability of plastics, featuring high performance and recyclability.
Key Characteristics
1. Excellent Elasticity & Sealing: Compression set and rebound接近传统 vulcanized rubber.
2. Outstanding Heat & Weather Resistance: Wide continuous service temp range (-60°C to 135°C), resists UV and ozone aging.
3. Good Oil & Chemical Resistance: Resistant to many oils, solvents, and chemicals.
4. Easy Processing & Recyclable: Can be processed via injection, extrusion, etc.; scrap is recyclable.
5. Low Density & Lightweight: Lower specific gravity than most rubbers, beneficial for weight reduction.Main Applications
Automotive: Seals, bellows, air ducts, gaskets.
Construction: Window/door seals, expansion joints.
Industrial/Consumer: Tool handle overmolds, hoses, gaskets, seals.
Others: Appliance seals, sports equipment grips.Processing Method
Injection Molding, Extrusion, Blow Molding
Key Certs/Standards
ROHS, REACH, UL, Can meet automotive industry standards (e.g., materials for TS16949 system).
