Chemprotex™ 400

Chemprotex™ 400 is a high performance chemical barrier material manufactured by laminating spunbonded polythene to a barrier film with a protective outer coating. It is the combination of film and polymer which provides a particle-tight material with excellent resistance to penetration and permeation by a broad range of liquids and gases.
