Product Description

Extremely High Temperature Resistant Fiberglass Yarns



Insultherm® is an extremely high temperature resistant sleeve commonly used as thermal protection for wires, cables and hoses that are subjected to continuous and extreme high temperature environments, such as engine manifolds and exhaust systems.

Insultherm® is braided from fiberglass yarns and saturated with high temperature resins that improve the product's stability and minimize irritating fiberglass dusting during cutting and installation. The sleeving is tough and durable, maintaining its tight structure under extreme vibration, abrasion, mechanical stress and temperature variations.

Insultherm® is available in a wide range of diameters. It cuts cleanly with scissors and installs easily over a variety of applications to either deflect or retain heat in environments up to 1,200°F.
