Do you know high temperature resistant properties of all kinds of thermoplastic elastomer TPE ?

For plastics and hard rubber,we usually use HDT Tester (VEKA temperature) to determine the High temperature tolerance.there are two calibrated parameters:one is Heat deflection temperature,the other is Vicat softening temperature. Classically, Heat deflection temperature is lower than Vicat softening temperature.

But for thermoplastic elastomer(TPE) industry,because of many kinds of TPE,many formulations,different adjustable hardness and property.there isn't any occupation standard to test the property of High temperature resistance.The following table, i make stocktaking of all types of thermoplastic elastomer TPE (including silica gel) for the high temperature resistance.

In the table, Silica gel has excellent high temperature resistance.However, silica gel is cross-linked elastomer which structure is different than thermoplastic elestomers(TPE) and thermoplastic elastomer TPE structure is different,I think the biggest difference is Silica gel can not be recycled but TPE can be.TPUE-SH in the table is a new products developed by our company in 2016 which is a thermoplastic elastomer has high temperature resistance.

TPUE-SH (thermoplastic elastomer) has excellent high temperature resistance(160-200℃), can be processing directly by injection molding machine. Because it is thermoplastic material, it can be completely recycled. TPUE-SH has excellent resilience,Good resistance to permanent deformation, texture smooth surface, excellent scratch resistant performance.what is more,TPUE-SH can be adhesion to ABS, PC, PC+ABS (overmolding) and replace silica gel/rubber.which also can be used in seals,push-button and some soft plastics has high requirment on high temperature resistance.
