TPE vs TPV

TPE vs TPV

TPE vs TPV

(OP)
Hi,

I am trying to over mold Polypropylene with a rubber like material and have narrowed it down to TPE (thermoplastic elastomer) and TPV (thermoplastic vulcanizate). I do not know the real differences and have some questions:

1)Can they both be overmolded onto polypropylene?
2)Which one is generally cheaper
3)Can I get them in any shore durometer? (I'm trying to achieve a soft quishy overmold)
4)Are there color limitations to either TPE or TPV?

Thank you!

 

RE: TPE vs TPV

TPV is thermoplastic vulcanisate.

Most common brand is Santoprene.

It can be any thermoplastic and any rubber dispersed but by far the most common thermoplastic matrix is PP, so it is very compatible with PP

The raw materials suppliers should be able to provide data as it is a very common practice.

Regards
Pat

RE: TPE vs TPV

(OP)
Thanks... But between the TPV and TPE..is there a reason one would choose one over the other? (While trying to achieve a overmold).

i.e. (Is one cheaper? Is one easier to process? Is one superior in properties? etc..)

Regards,
Sunny
