Abstract
The paper notes a crucial role of personal protective equipment (PPE) of skin integument during work with hazardous substances and liquidation of emergency at industry and transport enterprises. Earlier, two- and three-layer materials were used in the country and abroad to manufacture PPE of the isolating type. Currently, the leading companies manufacturing these means overseas for emergency PPE developed new four- and five-layer materials. These suits are present in the Russian market of PPE, however, their cost is quite high. For the first time in the country, the KazKhimNII JSC developed innovative multilayer LTL-1-2 material and its elastomer-based analogues. The universality of protective properties is due to selection of elastomers with different properties, specially developed formulations, and preparation method of composite materials. By protective properties, new isolating matters are not inferior to the best foreign materials of the highest level of protection. The developed innovative multilayer materials are designed to manufacture multifunctional isolating suits for personnel of industrial enterprises, objects of the Roscosmos State Corporation, and emergency response teams.
