What is Thermoplastic Vulcanizate (TPV)?

Thermoplastic Vulcanizate (TPV), also known as elastomeric alloy (EA), is classified as polyolefin thermoplastic elastomer family. TPVs are usually the combinations of polyolefin (Polypropylene or Polyethylene) and elastomer (SBR, NR, EPDM, NBR or Butyl). They vary with different composition of hard and soft segments. Most of the TPVs are compounds of PP and EPDM rubber.

TPV is produced in a reactive compounding process. During the dynamic vulcanization process of TPV production, completely cured elastomer particles (micron size crosslinked elastomer particles) homogenously distributed in a continuous matrix of polyolefin. This gives TPV compounds unique rubber-like properties, with the advantage of thermoplastic processing techniques.

TPV Features:
Resistance to chemicals and weathering
Acid, alkali, hydrolysis resistant and exhibit greater oil resistance than other TPEs
Good weather resistance.
Good anti-aging and anti-ozone properties.
Low compression set
The lowest compression set of any other thermoplastic elastomer
Flex fatigue resistance
Soft flexible touch with good fatigue and energy damping properties
High Resilience
Excellent tensile strength, tear strength and resilience
Clean scrap can be recycled and maintain over 95% of property even when recycled up to 5 times
Easy to process, no vulcanized is needed
Can be processed by injection, extrusion and blow molding
Heat resistant up to 135℃, sustain temperature ranges from - 40℃ to 135℃

TPV Applications:
TPV is mainly used in automotive industry, such as CVJ boots air bag cover.
And with its melt flow ability, it also used for building and construction, such as glazing seal, weather strip.
