PROLAST-O® — High performance FFPM seals

In specific application areas with agressive media and high temperatures, standard elastomers like NBR, Viton® or EPDM cannot stand up to the requirements any more. 

Perfluorelastomers are  top-class materials. They are extremely resistant against acids, amines, bases, ultra-pure de-ionized water, vapour, solvents and detergents. Even at high temperatures, seals made of Prolast-O® remain operational and therefore prolong the maintenance intervals and increase safety. 

With our many years of experience and our vast stock of tools we can produce the required seal within a short time.
