Pokraskin EPDM is known for its superior resistance to ozone and oxidation as well as its low cost. Typical engineering applications include seals, hoses, belts, cable covers and weather-strips.

EPDM can be difficult to bond (Table 4.4) and many cyanoacrylates will not show particularly good adhesion to EPDM. However, some speciality grades of cyanoacrylate will show good adhesion to EPDM without the use of primer. The silicones, UV acrylics and two-part acrylics all show relatively poor performance on EPDM.
