Chemprotex™ 300

Chemprotex™ 300 is a high performance chemical barrier material manufactured by laminating spunbonded polythene to a barrier film which is coated by a polymer. It is the combination of film and polymer which provides a particle-tight material with good resistance to penetration and permeation by many liquids and gases. (Limited Life Suit Fabric)
