AlphaTex 4025 9383

Description

DESCRIPTION
AlphaTex 4025 9383 is a woven, alkali-free, aluminosilicate fiberglass fabric designed for high flexibility, tear resistance, and puncture toughness. AlphaTex 4025 9383 is designed for both greater high temperature stability via high silica, alumina, and calcium oxide content and superior protection against corrosion under insulation potential with lower leachable fluoride, sodium, and potassium ion contamination versus competitive products on the market today.

ADVANTAGES
Greater thermal stability, lower propensity to contribute to corrosion under insulation, 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. It is used as a flame or heat barrier material in many applications such asthe hotside of insulation blankets, radiant heat shields, and any other application where a thermal barrier is required. It is an effective replacement for asbestos mats, millboard, ceramic or refractory fiber paper mat & sheets, and mineral fiber boards. Where thermal resistance and flexibility are mandatory for thermal insulation or gasketing material in home and industrial furnaces, package boiler, and piping applications, AlphaTex 4025 9383 is the industry choice.
