5G communication is inseparable from modified plastics. Modified plastics can be widely used in 5G base stations and smart terminals. It can be said that modified plastics are the core materials necessary for the realization of 5G technology. At the same time, the high-frequency and high-speed transmission of 5G enables low dielectric constant Modified plastics have become a new modification trend, and the modification of plastics is inseparable from the following additives.
1. Low dielectric glass fiber
Glass fiber mainly plays a reinforcing effect in modified plastics and increases the overall strength of the material. 5G modified plastics will be reinforced and modified with glass fibers with low dielectric constant. Manufacturers of low-dielectric glass fiber include Chongqing International Composite Materials and Taishan Glass Fiber.
2. Low dielectric filler
In order to meet the requirements of high-frequency communication, modified plastics will be modified to low dielectric constant. The fillers that can reduce the dielectric constant of plastics include hollow glass beads, cage silsesquioxane, mesoporous silica, soil removal, etc. Hollow glass microbeads are thin-walled, closed microbeads made of sodium borosilicate material through a special process; the cage-shaped hollow structure of cage-shaped silsesquioxane is equivalent to adding nano-bubbles into the resin matrix. The dielectric constant of the material can be lowered. Hollow glass microsphere manufacturers include 3M, Zhongke Yali, etc.
3. High dielectric filler
In order to meet the miniaturization design of electronic products, it is necessary to increase the dielectric constant of plastics. At present, functional fillers used in high-dielectric polymer matrix composites mainly include metal conductors, ferroelectric ceramics, organic semiconductors, etc., such as titanium dioxide, titanic acid, etc. Strontium, calcium titanate, barium titanate, barium strontium titanate, etc. Manufacturers of such additives include Shanghai Dianyang, Panzhihua Iron and Steel Titanium Industry, Lomon Billions, Fanhua Chemical, Wuxi Longao Electronics, etc.
4. Low dielectric flame retardant
At present, flame retardants include halogen-based flame retardants and halogen-free flame retardants. However, due to environmental protection requirements, halogen-free flame retardant modified plastics are an inevitable requirement and development direction. At present, some phosphorus-containing flame retardants have efficient resistance to Flammability and good dielectric properties, halogen-free and environmentally friendly, can be used in high-frequency materials. Low dielectric flame retardant manufacturers include Fuslin, Xianglin Chemical and other enterprises.
5. Anti-aging agent
Base stations are used more outdoors, so a lot of weather resistance and antioxidant additives are needed. There are many kinds of aging, so there are also many kinds of anti-aging agents. Anti-oxidants, anti-UV agents and light stabilizers are all kinds of anti-aging agents. Anti-oxidants can delay or inhibit the oxidative degradation of plastics. Anti-UV agents It mainly prevents the molecular chain from breaking due to ultraviolet radiation, and the plastic aging and yellowing. Anti-aging agent manufacturers are Li Anlong, Liansheng Technology, Guangzhou Zhiyi Chemical, Baoding Lekai, etc.
6. Low dielectric toughener
The filling and modification of inorganic powder reduces the mechanical properties of the composite material and deteriorates the processability. Therefore, it is necessary to add a toughening agent. Low-dielectric toughening agents include POE, SEBS, etc. POE manufacturers include ExxonMobil, Dow Chemical, Mitsui and LG, and SEBS manufacturers include Sinopec, Taiwan Rubber, Ningbo Keyuan, etc.
The function of the lubricant is to reduce the friction between the materials and the surface of the material and the processing equipment, and improve the molding processability of the modified composite material. The low-dielectric lubricants include PE wax, PTFE micropowder, etc. Such lubricant manufacturers include Xiduocun, Ge Rui, Shanghai Tuoju, Nanjing Tianshi and so on.
