Composite Radiant Heat Shield – Reflect-Therm HLC - Atlantex Manufacturing Corp.Reclosable Radiant Heat Shield – Product Overview

Reflect-Therm HLC sleeve shields components from the damaging effects of radiant heat. Reflect-Therm sleeving is a high-performance composite sleeve specifically designed to reflect upwards of 90% of radiant heat away from critical components. Manufactured with a highly-reflective and heat-resistant fabric, Reflect-Therm HLC will not melt, burn, or support combustion, and is resistant to common automotive, marine, and industrial fluids.

Reflect-Therm sleeving allows users to minimize thermal transfer, maintain peak operating efficiency, and prolong the life of critical components in heavy industrial, performance automotive, and other demanding applications. Reflect-Therm products can be manufactured with a variety of closures, and can even be fabricated for suit nearly any application.
