1.product features
◆ take polypropylene special resin as raw material, the non-woven are made by gellec unique
high temperature melting and spraying process.
◆ microfiber, lager specific surface area, high porosity, smooth, soft, good folding resistance.
◆ high filtration efficiency, good air permeability, small respiratory resistance.
◆ the electret is stable, the static electricity does not disappear in most applications,
and the filtration performance is stable.
◆ has good thermal insulation performance, water and oil absorption,
has a good flame retardant performance.
◆ non-toxic, tasteless, non-irritating, white and light.
