DESCRIPTION
AlphaTex® 4201-2-SS is a woven, alkali-free, aluminosilicate fiberglass impregnated with a specially formulated
silicone elastomer at 25% by weight with great flame resistance, abrasion, flex, tear, and puncture toughness. AlphaTex® 4201-2-SS is designed for higher mechanical strength at elevated temperatures via high silica, alumina, and calcium oxide content and superior protection against corrosion under insulation potential with lower leachable sodium ion contamination versus competitive products on the market today.
ADVANTAGES
Greater thermal stability, lower propensity to contribute to corrosion under insulation, weather resistant, fluid resistant, UV resistant, low flame-smoke-and-toxicity, easily sewn, and has a thin lightweight profile.
APPLICATIONS
This product is the next generation in high-temperature removable pads, flange covers, and valve covers.
