Heat-Shrinkable Heavy-Wall Tubing

This new low fire hazard material has been developed using the latest polymer technology to provide low smoke, low toxicity and low acid gas generation while being highly flame retardant and having a low calorific value.
ZCSM tubing is halogen-free and flame-retardant. A range of established tests, such as flame propagation tests, limiting oxygen index and temperature index have been carried out to assess the flame retardation properties of this material
Corrosion damage depends on the amount of acid gases generated when a material is burned, and therefore on the level of halogens and other acidic components in the insulation material. Pyrolytic analyses show only trace quantities of these substances in the ZCSM tubing. The low toxicity index rating derived from measurements of these and further Combustion products provide additional evidence of the material’s suitability for meeting special requirements of this kind
