iSuoChem CPP resin, Chlorinated PP

iSuo Chem Polyketone resin

So our engineer suggested polyketone resin + chlorinated EVA + CPP resin or polyketone resin + elastic rubber + Chlorinated PE, these two methods will be better with wax powder or abrasion resistant agent.

iSuoChem Chlorinated EVA

Until now, our company can supply TDS and the free samples of Polyketone resin (also called Ketone Resin), Chlorinated EVA (also called CEVA), and CPP resin for your test.
