ContiTech AG Protective Cloth for Optimum Protection Against Chemicals and Gases ContiBarrierSystem®

Greater safety, comfort and economy – these are the key advantages of the newly developed protective cloth material with ContiBarrierSystem®. When used in chemical protection suits, the new material design offers much greater protection from chemicals and gases. Hazardous substances such as chlorine, chlorinated hydrocarbons and ammonia are unable to penetrate the barrier layer. A high resistance to acids, lyes and aggressive chemicals, together with an excellent tear resistance, guarantees the highest possible level of safety for the wearer. At the same time, the material is around 30 % lighter at 450 g/m2 instead of the usual 700 g/m2, and thus much thinner and more flexible than previous materials. This doesn't just make it easier and more economical to work and process the material; it also increases the comfort for the wearer, meaning they can now move better and for a longer time. A mere 0.30 to 0.40 mm thick, the new protective cloth material consists of ten different layers. The inner and outer layers are made of elastomers. Depending on the customer’s requirements and area of application, different elastomers (fluorocarbon, chlorinated sulfonate polyethylene, butyl rubber) can be used both on the inside as well as on the outer layers. The fabric reinforcement materials can also be varied according to individual requirements. Two polymer layers have been integrated, independent of one another, into the protective clothing material via special adhesive layers. These make possible an exceptionally high level of impermeability and optimum safety, even if one barrier layer is destroyed or damaged.
