Arnitel® CM620-S

Technical Datasheet | Supplied by DSM
Arnitel® CM620-S by DSM is an unfilled and flame retardant, high performance, thermoplastic copolyester grade. It is a lighter, smarter, greener alternative to conventional rubbers thus, reducing environmental impact. It offers a unique combination of flexibility, strength and excellent processing characteristics. It exhibits excellent chemical resistance. It is processed by injection molding and extrusion. Arnitel® CM620-S is suitable for automotive, auto electronics & electricals, wire and cable applications. It allows for reliable solutions due its high temperature resistance (class T3 and T4, Class D (150°C) enabling thin and ultra thin wall designs, class E (175°C) >20 mm2 thick and thin wall). It provides sustainable and cost effective solutions (up to 50% lower system costs versus ETFE/FEP, 40% weight down versus XL PO at similar costs). The recommended dryers are dehumified dryer and vacuum dryer with N2 purge.
