A special type of protective material with a unique structure that provides reliable protection of the skin from chemically hazardous substances.
PMM is breathable providing comfort to those wearing protective clothing based on it.
Application of PMM
PMM clothes are made for:
- chemical and petrochemical industry
- handling hazardous chemicals
- pharmaceutical industry
- food-processing industry
- medical staff and patients
Due to its high vapor permeability, PMM is breathable, allowing the moisture to get out and preventing hazardous chemicals from getting in.
PMM conforms with the Unified sanitary, epidemiological, and hygienic requirements.
