Product Description
Protective membrane material (PMM)
The protective membrane material is used to manufacture highly
effective personal protective equipment for human skin. The unique
structure of the material lets the moisture pass through and
prevents the harmful chemicals from ingress to avoid the exposure
of vapors and mists of hazardous chemicals, solid particles, as
well as biological contamination.
PMM complies with the Unified sanitary, epidemiological, and
hygienic requirements.
PURPOSE
Protective membrane material (PMM) is the specific type of
protective material of unique composition that reliably protects
the skin against the health effect of exposure to highly toxic and
chemically hazardous substances as vapors, aerosols, drops, or
solid particles, as well as biological contamination. The basis of
this material is a polyamide imide-based selectively permeable
membrane (SPM) laminated (sealed using a special technology) on
both sides with woven polyester interfacing. Due to its high vapor
permeability, SPM is breathable, allowing the moisture to get out
and preventing hazardous chemicals from getting in. This property
keeps the skin dry, protecting against the exposure of aggressive
media. Thus, the protective membrane material has high
physiological and hygienic characteristics to ensure comfort to
those wearing protective clothing.
As far as the pollutant-free woven interfacing is used as a
liner, the membrane material achieves higher strength and
durability in case of the temperature jump, higher stability to
deformations and damages during operation, which increases its
service life.
PMM with the selectively permeable membrane ensures the
following:
higher protection properties;
comfort for the protective clothing user due to the material
vapor permeability.
