We are a manufacture specialized in producing composite nonwoven products and developing new products. At present following products are available: 1. Breathable, waterproof and heat-insulated material used as roof membrane on wooden house; 2. breathable and waterproof material applied in food and pharmaceutical product; 3. Elastic nonwoven used in bodybuilding. We have got three national patents for our products and so far our products have been export to many countries like Italy, Russia, Greece, and Poland etc. Compounded of microporous film and nonvowen, breathable waterproof membrane enjoys excellent wind-protection, waterproof, air permeability and tensile strength. With pressure difference of surrounding, the material will breathe automatically. In other words, fresh air can go into the inner space while surplus moisture gives off through the pores so as to avoid the formation of condenser water. Its wind-protection and air permeability provide an ideal condition for preventing buildings from outer influence and loss of heat, breathable waterproof membrane can be used to substitute other expensive roof materials due to its high quality long live but low price. FMFB 130 Breathable waterproof Membrane is a second-generation breathable membrane, conforming to the high performance and professional standard.
