Waterproof and breathable three-layer and five-layer composite material

The three-layer and five-layer composite material is a high-performance polymer with high water pressure resistance. At the same time, the micropores can smoothly discharge sweat vapor. The PTFE membrane with appropriate pore size can block bacteria and viruses. Its strength **, stable properties, good biocompatibility, good thermal stability, and easy to form.

The abrasiveness of dust to the filter material is called the abrasiveness of dust, which is related to the shape, size, hardness, dust concentration and airflow speed of the dust.

Common dusts such as aluminum powder, silicon powder, coke powder, carbon powder, etc. are highly abrasive dust. For dust with high abrasiveness, when choosing to make a filter element, you must use a filter material with good wear resistance, such as High-strength, fine-denier polyester fiber non-woven fabric, or impregnated polyester fiber non-woven fabric to increase the wear resistance of the filter material.

The three-layer and five-layer composite material is an environmentally friendly material. It is made of polytetrafluoroethylene (ptfe) material through special processes such as mixing, extrusion, extrusion, calendering, and biaxial stretching.

The pore size of the material is small and the distribution is concentrated. Surface filtration is achieved to achieve a dust removal efficiency of 99.9%~99.999%. For some extremely small particles with a diameter of 0.1um-0.3um, it can better prevent fine dust from entering the filter material.

PTFE waterproof and breathable membrane can operate at a continuous operating temperature of 240°C and an instantaneous temperature of 260°C.
