Thermo Plastic Silicon
Vulcanizate - TPSiv is an alloy of Sillicone rubber with Engineering
Thermoplastic materials like Polyamide.
 |
TPSiv has high temperature elastomeric perfomance
of sillicone rubber with the thermoplastic behaviour of
engineering thermoplastics. |
|
TPSiv has good thermal properties and is a high perfomance
elastomeric material that can have a continuous temperature
as high as140ºC. |
|
It can exhibit good abrasion resistance. |
|
Their high performance at elevated temperatures make
them suitable for automative applications, where resistance
to oil and chemicals at higher temperatures are key property
requirements. |
It is therefore not surprising that they cost
much higher compared to the conventional TPOs (Thermoplastic Olefinic
Elastomers) or other thermoplastic elastomers. The high cost restricts
its usage only for very demanding applications. The Processing cost,
because of predrying for 6-8 hours at 80ºC, to eliminate moisture,
is also higher compared to the other Thermoplastic Elastomers.
However for demanding applications like tubing for petroleum industry,
TPSiv is the ideal choice.The supplier of TPSiv has increased development
activities and is exploring new applications and new marketing regions
like Japan and China. It would therefore not be surprising that
TPSiv would find more applications in the near future.
