Thermoplastic Vulcanizate (TPV)
Thermoplastic Vulcanizate is a vulcanized thermoplastic elastomer developed using resin and synthetic rubber technology. TPV is derived from olefin-based rubber and olefin-based resin and it does not require compounding or vulcanization processes like rubber does. Similar to a general purpose resin, it can be moulded and its natural grade can be easily coloured.
There are various grades of the elastomer available, ranging from flexible grades like vulcanized rubber to semi hard grades such as low density polyethylene. These have unique characteristics to suit individual applications.
- Superior lightness
- Rubber elasticity
- Heat resistance
- Cold resistance
- Weatherability, Ozone resistance
- Chemical resistance
- Electrical insulation performance
In addition, the thermoplastic elastomer features a number of excellent secondary processability characteristics, including:
- Coating performance
- Thermal adhesiveness
- Vacuum forming performance
- Interior and Exterior Automotive parts
- Building materials
- Appliance parts
- Sporting goods
- Consumer goods
TPV is the lightest general purpose elastomer material with a density of at most 900 kg/m3. By using TPV instead of ordinary vulcanized rubber, product weight can be reduced by about 30%
TPV is ideal for use in high temperature applications with a heat resistance superior to other elastomers.
TPV has outstanding rubber elasticity at high temperatures, with deformation recovery superior to vulcanized rubber in long-term compressing set testing.
Excellent resistance to water, acids, alkalis, alcohols, acetone and vegetable oils. However, care must be taken because it is susceptible to attack by aromatic organic solvents, gasoline, and mineral oil etc.
The B (Black) Grade of TPV has outstanding weatherabilty and is suitable for outdoor use. Both the B and N (Natural) grades have superior ozone resistance.
Similar to polyethylene and polypropylene, TPV has outstanding electrical insulation performance.
