Buna® EP production technologies: two versatile processes

Buna® EP copolymers are made by copolymerization of ethylene and propylene using Ziegler-Natta catalysts. These catalysts are formed in-situ by reaction of vanadium salts and aluminum alkyl halides.

LANXESS is the only manufacturer worldwide that offers both solution and suspension (slurry) technology.

The combination of two different processes enables LANXESS to produce a very wide range of EP rubber products from very high molecular weight and high ethylene grades produced in suspension to amorphous, moderate molecular weight grades. Both processes offer distinct advantages.
