EPDM 644 is 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. Main Characteristics: Medium diene Medium molecular weight Applications: General purpose gaskets and moldings Extruded profiles and hoses Notes: Can be used in contact with all foods except water in oil emulsions, high or low fat, and low moisture fats and oil. Adhesives only. Complies with U.S. FDA 21 CFR 177.2600 U.S. FDA 21 CFR 177.1520 U.S. FDA 21 CFR 175.105 U.S. FDA 21 CFR 177.1210 Consult the regulations for complete details.
