ChemMAX® 2

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

ChemMAX® 2 uses Dow Saranex® 23P barrier film – soft, flexible and tried and tested around the world over decades. See Lakeland’s guide to the selection of limited life coveralls for hazardous chemical protection.

ChemMAX® 2 fills the gap between the limited ranges offered by competitors and offers an extremely soft and flexible fabric with a more competitive option for many applications requiring chemical protection. Tests indicate ChemMAX® 2 offer equivalent or better permeation barrier than more expensive alternatives for 63% of chemicals tested! In additions it’s mechanical strength properties are equal or better according to most CE measures.

This means in many applications where more expensive competitors are used ChemMAX 2 is a realistic alternative… and it is lighter, softer and more flexible so will enhance comfort levels… and will reduce cost as it is considerably less expensive.

The table above shows the result of standard CE certification required mechanical strength tests on fabrics and seams to provide a general profile of the garment mechanical properties. These are a reflection of controlled lab tests and actual performance of nonwoven fabrics and films may vary. For more detail on each of these tests please see the page at CE Certification and Marking.

Chemicals are tested at a concentration of 100% or saturation unless otherwise stated.

Beware! Chemical testing according to EN 6529 is conducted at 25% oC +/- 5oC. permeation rates may vary considerably at higher ambient temperatures

Material Safety Data Sheets on many commonly used chemicals can be found here.​​ 

(Lakeland make no claim or guarantee that the information on these sheets is correct).

Normalized breakthrough times are a reflection of controlled laboratory tests according to EN6529 (or previous versions EN 369 & EN 374-3). “Normalized Breakthrough” is defined as the time to reach a measured PERMEATION RATE of 1.0µg / min / cm2. This DOES NOT indicate the time to any measured breakthrough of a chemical nor that NO TRACE of the chemical has permeated through the fabric in less than 480 Minutes. Further, results may vary according to lab, detection methods and sensitivity, and ambient conditions such as temperature.

These results are therefor not intended to indicate any guaranteed duration of “safe use” for any garment but rather to provide a basic guide to preliminary selection and to indicate chemical protective capabilities relative to each other

Chemical suit selection should also be made on the basis of design requirements as well as fabric chemical barrier
