Description

Chemical protective glove chloroprene

Description:

Permeation level: 3

Heavy-duty design

Permeation is the process by which a chemical moves through the material of a protective glove on a molecular level. The time from the initial contact between the chemical and the glove to the permeation of the material is the breakthrough time.

Important information:

The information given is based on experience and laboratory conditions and is designed as a guide. However, the actual suitability of a glove depends on the individual conditions of its use and must be confirmed by an appropriate test under operational conditions. Given the variety of materials and chemicals used, the possibility of incompatibility or usage problems for the wearer cannot be excluded in individual cases. We would be happy to advise you about optimum solutions.
