A semi-amorphous ethylene-propylene-diene terpolymer (EPDM) grade designed for molded and extruded applications. It is ideally suited for general-purpose gaskets and moldings, extruded profiles, and hoses. The combination of medium viscosity and low crystallinity allows for good balance of processability, low temperature properties, and product performance.

用途:

Molded automotive and industrial parts
Hose and tubing
Extruded profiles including weatherstrips
Belts
General purpose gaskets and moldings

优势:

The combination of medium viscosity and low crystallinity allows for good balance of processability, low temperature properties, and product performance.
