T823.0 ETFE2183 COMPOUND 25% GLASS FIBER

Engineered with short fiber reinforcements to provide precise levels of electrical conductivity

Our expanding portfolio of offerings includes colorants, advanced composites, functional additives, engineered materials, and Dyneema®, the world’s strongest fiber™. Our innovations cover a broad range of products in several end markets, from insulator rods in power distribution to life saving vests and protective materials for the military and law enforcement agencies manufactured using Dyneema® fiber. As the world continues to shift from operating in a linear economy to a circular economy and to a lower carbon footprint, Avient is proud to be a part of the solution.

Carbonateds Black colorant created without the addition of carbon black pigments.

Based on the raw materials used and manufacturing practices, these materials have a different product carbon footprint (PCF). LSR will generally withstand high levels of exposure to cleaning and disinfecting chemicals, but is susceptible to attacks by concentrated solvents (gasoline, mineral spirits) and acids (sulfuric acid, carbonic acid, citric acid found in car batteries, sodas and juices).¹
