Composite Heat Release Technology for Firearm Barrels Overview and key characteristics of Composite Heat Release

Vehicle Light Heat Sinks Therma-Tech™ provided lighter weight solutions with required thermal conductivity for automotive light heat sinks

Geon™ Bold vinyl solutions are dark, richly colored materials that stand up to the elements, especially heat build up, without losing their intensity or performance for windows, fencing, decking, and siding. Caption: This prototype heat sink for an LED ceiling light was molded in PVC from 3D printed inserts produced at the PolyOne Innovation Center in Avon Lake, Ohio.

If the heaters are on continuously, there is not enough heat being produced from shear. To increase shear heating, increase the screw rpm and back pressure. Increasing the back pressure increases shear heating of the material.

These additive solutions create a char or gas that reduces oxygen at the source of flame, leading to components that become self-extinguishing, and potentially lowering the heat release rate over time. Fire time to ignition is increased while heat release and fire spread are reduced, resulting in enhanced fire safety for life and property. TARGET APPLICATIONS • Aerospace • Appliances • Automotive, including electric vehicles • Building & construction • Electrical & electronics • Public transportation • Recreational vehicles, bikes & scooters • Wire & cable IMPACT • Reduce spread of fire and heat release • Limit quantity of smoke to allow people to find their way to safety more easily • Limit toxicity and acidity of gases so people are less likely to be overcome by fumes • Enhance char formation, avoiding droplets which can proliferate fire • Meet regulation and legislation requirements Copyright © 2024, Avient Corporation.
