High quality solutions in rubber, polyurethane and silicone.
Neoprene, Nitrile, EPDM, Viton and Natural are all commonly known grades of rubber. This page is intended to illustrate the wide range of grades available and the many variations they have. All of the product areas listed on the left hand menu are manufactured using one of these compounds. This list is by no means definitive and should not be used as a complete solution, but should illustrate as a guide to the main compound choices available to suit your requirement whether you need a moulding, a seal or an expansion joint.
