Viton, Ryton, Neoprene, teflon???!!
Viton, Ryton, Neoprene, teflon???!!
(OP)
I just need to know the advantages/disadvantages of using these four different Ploymers: Viton, Ryton, Neoprene & teflon. from the view point of compressibilty, heat/cold resistance, chemical reaction/stability with other chemicals, etc..

RE: Viton, Ryton, Neoprene, teflon???!!
Neoprene is a trade name for polychloroprene. Max continuous temp 95C, intermittent 125C,Fair to excellent resistance to your list except benzene (rated unsuitable).
Ryton - never heard of it but if you google ryton polymer and click on the Chevron Philips link you will find an information sheet.
RE: Viton, Ryton, Neoprene, teflon???!!
Teflon is polytetrafluoroethylene (PTFE), a plastic, while Viton is a fluoropolymer elastomer (rubber) with varying compositions somewhat similar to PTFE.
I had never heard of Ryton either, so you learn something new every day. It seems like it's a plastic material, like Teflon, while neoprene and Viton (FKM) are rubbers/elastomers.

RE: Viton, Ryton, Neoprene, teflon???!!
All of the properties you are interested in could be googled, or look them up on matweb.com. Chemical resistance can be a little tougher to figure out, if you tell us exactly what chemical, we could tell you a bit more. Generally, chemical resistance is best with Teflon, then Viton, then PPS, then neoprene, though there are some gotchas in that list.

Thanks for pointing out the difference between Teflon and Viton.
