Teflon waterproof and breathable membrane is made through special processes such as mixing, extrusion, extrusion, calendering, and biaxial stretching.
Due to the characteristics of ptfe fibrillation, when performing unidirectional stretching (i.e. longitudinal stretching), the ptfe polycrystalline aggregates begin to extend and form some fibrils. The fibrils are parallel to the stretching direction. At the same time, the fibrils The length increases.
The cross-section of ptfe fibrils is wide and thin, its maximum width is about 100nm, and the smallest fibril is ?0.5??1.0nm.
? Undertake various filter material coating processing services. Our company will perform coating processing according to the coating substrate provided by the customer or the coating substrate specified by the customer.
The key to its Teflon waterproof and breathable membrane technology is the optimized combination of speed ratio, pressure ratio, operating temperature and other parameters. Our company can realize online control of air permeability, thickness and void ratio according to the ratio and pore-forming medium. To meet the different needs of users.
We have a professional polymer R&D team with strong R&D capabilities and a number of invention patent certificates and practical patent certificates.
It has a full set of advanced production equipment, an advanced clean room and an independent composite slitting workshop to ensure the production quality of ptfe membrane.
