Calmont Wire and Cable

is distinguished by its extreme limpness and flexibility. It is the most limber of all the ultra-fine stranded constructions offered by Calmont. Silicone rubber insulation compounds are inherently soft and pliable, yet resist the plastic flow that characterizes many insulation systems.

Silicone compounds can be tailored for a variety of applications such as extreme low temperature flexibility, extreme heat resistance, optimum radiation and flame resistance, strength and purity.

FEATURES	APPLICATIONS
Resistant to temperature extremes Excellent electrical characteristics Easily stripped Light weight Corona resistant High radiation resistance	Pliable and flexible even in the high voltage and high altitude conditions of Aerospace. Extremely suitable for biomedical usage where flexible instrumentation cables are needs. A type of Siliflex is available that will meet FDA standards. Magnetic disc drive and print head cables, where flexibility and low noise are needed.
