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. |
