ADVANTAGES Value for money Mechanical strength Excellent flexibility Good puncture and tearing resistance Suitable for cold environments Good puncture and abrasion resistance No risk of proteinrelated allergies Good flexibility Good thermal resistance Excellent chemical resistance Flexible and elastic High chemical resistance RESTRICTIONS Not suitable for handling hot parts Risk of allergies caused by the proteins in the natural latex Not recommended for cold environments Poor mechanical properties Poor mechanical properties The permeation time for a given chemical product, i.e. the time taken for the chemical to penetrate the glove, at a molecular level; in some cases, there is no visible deterioration of the glove. 1. PERMEATION TIME The degradation index of the glove in contact with a given chemical product, i.e. the degree of deterioration of the glove shown by an alteration of its physical properties (e.g. softening, hardening, etc.). 2. DEGRADATION INDEX SELECT THE MOST APPROPRIATE CHEMICAL GLOVE FOR YOUR NEEDS USING THE THREE STAGES BELOW: CHEMICAL PROTECTION To address these varied risks, Mapa Professional provides a wide range of protective gloves made from various polymers - including latex, nitrile, polychloroprene, butyl and fluoroelastomer - each providing specific protection based on the end user’s needs. Chemical hazards are not limited to the chemical industry - they are present in many sectors like manufacturing, agriculture, healthcare, cleaning, construction, mining, pharmaceuticals and automotive. In these environments, workers are frequently exposed to substances that can be more or less aggressive, including oils, acids, solvents and other hazardous chemicals. To characterise the performance of the elastomers and plastics used to manufacture safety gloves, tests are carried out to determine the behaviour of these materials when confronted with the various families of chemical products. Mapa Professional takes these different parameters into account to determine the relative performance of the different families of gloves and hence help you make the best possible choice.
