In terms of the performance characteristics of thermoplastic vulcanizates (TPV), their primary applications lie in the following areas:
1. Sealing (building and automotive weatherstrips, sealing rings);
2. "Soft Touch"-providing a soft tactile feel (handles, grips);
3. Impact resistance, vibration damping, and flexibility (casters, buffer blocks; wires, cables, and hoses);
4. Plastics modification-enhancing the toughness and impact strength of materials.
Distinguished by performance attributes that set it apart from general thermoplastic elastomers, TPV finds its applications leaning more heavily toward industrial products:
1. High-temperature resistance: Standard fully vulcanized PP/EPDM grades can withstand temperatures up to 135°C, while engineering-grade TPVs-such as those introduced by DuPont-can endure temperatures exceeding 150°C;
2. Solvent and oil resistance: Due to the presence of a cross-linked rubber particulate phase within its structure, TPV typically exhibits superior resistance to solvents and oils.
