ChemMax™ 4 fabric uses a combination of multiple polymer films laminated to spunbonded PP substrate to create a high barrier against a wide range of hazardous chemicals. Tough and durable, ChemMax™ 4 can be used multiple times if undamaged and uncontaminated. The high-tech European-manufactured extrusion fabric construction results in a smoother, softer, more flexible and more consistent finish than bonded or glued competitors and with none of the ‘pinching’ or crushed bond points seen in competitor fabrics.ChemMax™ 4 is tested against a full range of chemical warfare agents for anti-terror and civil defence operations. Combined with a double-zip and storm flap front fastening design, cushioned double-layer knee pads and Lakeland's Super-B style coverall for superior fit, wearability and durability, this makes ChemMax™ 4 the pinnacle for Type 3 & 4 high hazard chemical protection. Note that ChemMax™ 4 Plus is available as standard in yellow, with green and khaki available on request - minimum order quantities may apply.
