Release time:2020-09-30 14:08 Reading times:
Characteristics:
● Take polypropylene special resin as raw material, the non-woven are made by our unique high temperature melting and spraying process.
● The fiber diameter is small, the specific surface area is large, the porosity is high, it is smooth, soft, and has good anti-wrinkle ability.
● High filtration efficiency, good air permeability and low breathing resistance.
● The electret is stable, and the static electricity does not disappear in most applications.
● Good thermal insulation performance, water and oil absorption, and good flame-retardant performance.
● Non-toxic, tasteless, non-irritating, white and light.
