TPV

產(chǎn)品詳情

Thermoplastic Vulcanizate (English: Thermoplastic Vulcanizate), TPV for short, Chinese name for Thermoplastic Vulcanized Rubber (English Thermoplastic Rubber), TPR for short, but this name is easily confused with other types of thermoplastic elastomers Together, because usually thermoplastic elastomers are also called thermoplastic rubbers, especially styrenic elastomers. At least in China at present it seems that "TPR" has become its proper name. The mention of TPR means SBS, SEBS Such styrene-based elastomers are thermoplastic elastomers based on the base material, which is inseparable from the large consumption of styrene-based elastomers in the field of consumer and end consumer products.

In terms of the performance of thermoplastic vulcanizates, it has applications in the following areas:

1. Sealing (construction / auto seals, seals)

2.SOFT TOUCH, soft feel (handle, grip)

3. Impact resistance, shock resistance; flexibility (casters, buffer blocks; wires, cables, hoses)

4. Plastic modification to improve the toughness and impact resistance of the material.

Since the properties of thermoplastic vulcanizates are different from general thermoplastic elastomers, its applications are more inclined to industrial products:

1. In terms of high temperature resistance, conventional fully vulcanized PP / EPDM can reach 135, and the engineering thermoplastic vulcanizate introduced by DuPont can withstand more than 150;

2. In terms of solvent resistance and oil products, TPV is generally more resistant to solvents and oils because it has a crosslinked rubber particulate phase.
