EPDM Ethylene Propylene Rubber

It consists of two types: EPM, which is a copolymer of ethylene and propylene, and EPDM, which is a terpolymer (formed from three monomers) of ethylene, propylene, and a small amount of diene. This diene provides the unsaturation necessary for the rubber to be vulcanized with sulfur. The material is used in a variety of products such as O-rings, gaskets, window seals, door seals, and other rubber seals, cable insulation, roller coatings, bellows, conveyor belts, hoses, rubber plugs, and rubber sheeting.

For example, we use EPDM for our rubber feet and cable glands, as outdoor environments are perfectly suited for EPDM.

Why not mold a flat sheet in EPDM that we can then punch or water-cut to the correct dimensions? We can create flat gaskets without manufacturing mold tools.

It possesses good elasticity, like other rubber types, but has additional properties that make it particularly suitable under certain prevailing conditions. EPDM can withstand both lower and higher temperatures compared to other rubbers, with higher temperatures achieved by incorporating peroxides into the vulcanization system. Thanks to its properties, it is also a unique sealing material that is exceptionally resistant to factors such as aging. In injection molding, it is one of the most common materials. We work with hardnesses ranging from 40º Shore to 90º Shore and in several different colors such as gray, blue, and black. Black is, however, the most common.
