Santoprene NSF-61 grade is a Thermoplastic Elastomer (TPE) made from a cross link mixture of EPDM rubber and Polypropylene. This combination offers excellent flexibility and durability that are consistent with natural rubber.
1) Santoprene is polypropylene cross linked with EPDM rubber. Not to be used as a modifier. If you want to modify another polymer, use Exxon Mobil Exxelor or other impact modifier. 2) Santoprene does *not* have PVC in it, or a flame retardant, unless you're looking at one of the specialty grades.
