Dow Tyrin® CM674 Elastomer Formulation (discontinued **)
Categories:	Polymer; Thermoplastic; Elastomer, TPE
Material Notes:	25% chlorine. Tyrin® chlorinated polyethylene thermoplastic resins offer the compounding and fabrication industries end product properties in a range of hardnesses, and behave much like flexible PVC in many uses. Can be calendered, injection molded, or extruded into tough, chemical and weather resistant products that can also provide built-in ignition resistance. Performance highlights include: inherent flexibility with plasticization; inherent chemical and ignition resistance; compatibility with PVC, PE, SAN, ABS, and other polymers, excellent low temperature properties, resistance to weathering, acceptance of fillers and heat/light stabilizers.
