This strip is manufactured from black EPDM (ethylene propylene diene monomer, a type of synthetic rubber). Suitable for two panels, one up to 2.5mm thick, the second up to 5mm thick. The overall width is 28mm and the overall height is 18.2mm. Supplied in 50m lengths.

EPDM gasketing has a low residual displacement after the compression has been removed and can tolerate a wide range of temperatures. UV, oxygen and ozone have little effect on EPDM gasketing, which makes it suitable for outdoor applications, and it tolerates water, salt fluids, steam, alcohol, glycol and weak acids or alkalis but not oils or hydrocarbon-based solvents.
