PTFE bubble point membrane composite material is a membrane with screening function.
Polytetrafluoroethylene is a linear polymer. Due to its high polymer chain and low cohesive energy, there is no suitable solvent to prepare the casting liquid. It can only be sintered, cut, stretched or extruded to form a film. .
The intergranular region forms pores and becomes a microfiltration membrane.
If combined with polyethylene mesh, it can be made into a high-strength microfiltration membrane.
It has good chemical stability, is resistant to strong acids, strong alkali, strong oxidants and organic solvents, and can be used at high temperatures.
Although a certain amount of colorant is added to the ptfe bubble point film composite material, it still has good electrical insulation and is suitable for the insulation and classification identification of wires, cables, and electrical devices.
Because it has high tensile strength and insulation, it can be used in a wide range of temperatures (-180℃~250℃), its porosity can reach more than 85%, and its pore diameter is 0.2-3um, which can effectively insulate The water point and waterproof grade can reach IPX7 or above, and it has the best legibility during use. Therefore, it is an indispensable product in aviation, navigation, aerospace, communications, electronics, military, weapons and other industries.
After years of painstaking research and development, Suzhou New Material Technology Co., Ltd. not only has strong R&D strength, complete testing methods and domestic advanced experimental equipment, but also attracted a large number of outstanding technical talents.
