We are not limited to the four common elastomers mentioned above but can work with almost any elastomer you might
require such as, ethylene propylene (ERDM), ethylene acrylic (EA), chloroprene (CR), high/low temperature nitriles,
conductive rubbers, carboxalated rubber etc. We have a state of the art laboratory and can modiy elastomers in many
to include temperature, abrasion, high rpm, durometer etc. |
