Product Description:
CHS21 is a flexible, flame-retardant polyolefin heat shrinkable tubing. It is low smoke generating, abrasion resistant and in case of burning produces no dioxin. CHS21 has excellent electrical and physical properties, including excellent acid fastness and corrosion resistance. (CHS21 Clear is not flame retardant)
