ZHTM thick-walled heat shrink tubing
ZHTM thick-walled heat shrink tubing, a flexible, low-toxicity shrink tubing for fire safety applications. This material exhibits excellent fire safety properties combined with low smoke emission and low development of acidic gases, while maintaining good mechanical and fluid-resistant properties.
Applications for ZHTM
Used for insulation and protection of cables, harnesses, and electrical and electronic components in confined spaces, such as in maritime applications, public transport systems, and offshore installations, to mitigate toxicity risks, or where equipment would be irreparably damaged by aggressive products during combustion.
