Chemicals and Gases

Material for protection against aggressive media for civil and military applications

The integrated ContiBarrierSystem® offers protection against toxins, chemicals and gases. Hazardous substances such as chlorine, chlorinated hydrocarbons and ammonia are unable to penetrate the barrier layer. A high resistance to acids and lyes, together with an excellent tear resistance, guarantees the highest possible level of safety. At the same time, the material is around 30 % lighter and thus much thinner and more flexible than previous materials.

Personal Protective Equipment - now with newly developed 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.

With regard to the U.S. market, ContiTech's elastomer-coated materials for protective suits also fulfill U.S. fire safety standards (NFPA).

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.
