Why mica tube is popular?

Since the 1990s, with the rapid development of highways, radial tires have generally been used in automobile tires. Mica tubes have become the first choice for radial tires due to their excellent wear resistance and adhesion, but their Young’s modulus is small and resistance And the thermal deformation is not obvious, which greatly shortens the service life of the tire.

Radial tires are gradually replaced by steel wires and polyester. Manufacturers of mica board said that in the next few years, in order to make up for the defects of mica board, major companies will generally modify mica board and develop new high-strength polyamine cords. Today, the strength of newly developed cords in Japan can reach 12CN/dtex. The company adopts modified mica board, which has the characteristics of low calorific value, light weight and durability, and is used as the frame material of radial tires.

Since the 1980s, BCF woven carpets have been favored by people and are suitable for various indoor performances. For traditional BCF woven carpets, mica board accounts for 58% and polypropylene accounts for 42%}}-8}. The BCF production process adopts a one-step method, and a flexible FMS production system has been developed to produce BCF in various colors. The post-processing adopts air deformation instead of mechanical deformation, and the processing speed is fast, which can form three-dimensional crimped high loose yarn. By rotating spinnerets with different cross-sectional shapes, the hollowness of the fiber can be increased, and excellent aromatic mica board fibers with high strength, coverage, expansion, durability, stain resistance, and easy cleaning can be obtained. Due to its high strength, light weight, and high temperature resistance, it is widely used in aircraft barrier networks, life rafts, parachutes, national defense and military textiles, and even part of it is used in aerospace technology. Manufacturers of mica board said that in civilian fibers, it also makes full use of the excellent toughness of nylon. After modification, water absorption can be reduced and dimensional stability can be improved. Used in fishing nets, the service life is 3-5 times that of cotton nets. It can also be used for pavement stone flow protection, fence nets, luggage nets, container transportation safety nets, medical pipelines, mesh elastic bandages, medical sutures, etc.
