ChemMax® 3

Advanced Chemical Protection for Industry, Emergency Response and Law Enforcement. ChemMAX® 3 is soft, flexible and tough with an extensive chemical barrier - use with Permasure® to instantly calculate Safe-Use Times

ChemMAX® is Lakeland comprehensive range of coveralls for Type 3 & 4 protection against hazardous chemicals.

ChemMAX® 3 fabric features a UK-manufactured multi-layer barrier construction to provide protection against a wide range of hazardous chemicals. Co-extruded fabric technology means a smooth and flexible fabric that is free from the crushing and pitting suffered by adhesive or heat laminated barrier fabrics – so thickness, permeation and protection is uniform throughout the fabric surface.

NOTE: Permeation test data relates to "Normalised Breakthrough" which measures the time for the permeation rate to reach a specific speed (In CE EN 6529 testing, 1.0µg/min/cm2 and in US ASTM F739 testing, 0.1µg/min/cm2). This does not indicate when the chemical first breaks through the fabric and is not an indication of how long the suit can be safely used as the chemical may have permeated through the fabric before the Normalised Breakthrough time. This might be critical in cases of chemicals with high toxicity.
