Santoprene® (PP and EPDM)
Flouorosilicone Rubber
Polyurethane Rubber
Epichlorohydrine Rubber (ECO)
Polysulfide Rubber
Cholorsulfonated Polyethylene (CSM), (Hypalon®)


Most of these materials have been invented to provide better resistance than natural materials like wood or metal to wear and impact, chemicals, degredation from environmental sources such as moisture, temperature fluctuation and UV.

One of the properties of engineered plastics that make them it difficult to bond to, the surface slickness, is the result of the manufacturing process. Engineered plastics can be bonded to themselves and to other plastics and substrates including glass, ceramic, metal, stone, aggregate and concrete among others, but require careful preparation and BONDiTTM brand adhesives manufactured by RELTEK LLC. BONDiTTM products are among the few available that can be used to bond engineered plastics to substrates with differing coefficients of expansion (COE). BONDiTTM products are renowned for their resistance to harsh environments and for withstanding long term deployment without debonding.

Please see the discussions by substrate for our general recommendations for each substrate -- as they do differ, depending on several factors.
