LANXESS is a major global supplier of Ethylene-Propylene Rubbers EP(D)M. LANXESS offers all EP(D)M grades under the brand name Keltan®.

The general term "ethylene-propylene rubber" refers to two different kinds of polymers:

EPM represents a copolymer from ethylene and propylene monomers; EPM is entirely saturated and therefore requires vulcanization by radiation or products that release free radicals, such as organic peroxides.
 
EPDM denotes a terpolymer based on three monomers: ethylene, propylene and a non-conjugated diene; EPDM grades have a residual unsaturation in the side chains and can therefore be cured with sulfur and accelerators.
Its heat resistance is distinctly better than that of Natural Rubber, SBR and Butadiene Rubber.
The molecules of both EPM and EPDM have a completely saturated hydrocarbon backbone, through which excellent ozone resistance and very good resistance to heat and oxidation are achieved.

The versatility of Keltan® elastomer, high product quality, high supply reliability and high service level enables high performance for our customers, products and industrial solutions.

The Keltan® portfolio consists of a broad range of global grades with a diversity of properties that offer freedom in recipe formulations, product design and processing windows. This, in turn, allows our customers to optimize
between product performance and cost efficiency.
