First, Phosphate flame retardant used in building materials industry
Polycarbonate sheet has good light transmittance, impact resistance, UV radiation resistance and dimensional stability of the product and good molding processing performance, making it has obvious technical performance advantages over the inorganic glass traditionally used in the construction industry. China has more than 20 hollow board production lines for polycarbonate building materials, and it needs to use about 70,000 tons of polycarbonate annually, and it will reach 140,000 tons by 2005.

 
Second, automobile manufacturing
Polycarbonate has good impact resistance, thermal distortion resistance, and good weather resistance, high hardness, so it is suitable for the production of various parts for cars and light trucks, mainly in the lighting system, dashboard, heating plate, in addition to Froster and polycarbonate alloy bumper. According to the data from developed countries, polycarbonate is used in the proportion of 40% to 50% in the electronics, electrical and automobile manufacturing industries. The proportion of China’s use in this area accounts for only about 10%. Electrical and electronic and automotive manufacturing are the pillars of China’s rapid development. Industry, the future demand for polycarbonate in these areas will be enormous. It is estimated that in 2005, the total number of automobiles in China will reach more than 3 million, and the demand will reach 30,000 tons. Therefore, the application of polycarbonate in this field is extremely promising.
Third, medical equipment
Since polycarbonate products can withstand steam, cleaning agents, heating, and high-dose radiation sterilization without yellowing and physical degradation, they are widely used in artificial kidney hemodialysis equipment and others need to operate under transparent and intuitive conditions. Need repeated sterilization of medical equipment. Such as the production of high-pressure syringes, surgical masks, disposable dental appliances, blood separators and so on.
Fourth, the use of phosphate flame retardants in aviation, aerospace applications
With the rapid development of aviation and aerospace technology, the requirements for various components in aircrafts and spacecrafts have been continuously improved, making the application of PCs in this field increasingly increasing. According to statistics, there are 2,500 polycarbonate parts used on only one Boeing aircraft, and about 2 tons of polycarbonate is used for a single aircraft. On the spacecraft, hundreds of different configurations of fiberglass-reinforced polycarbonate parts and astronauts’ protective equipment were used.

 
Fifth, the packaging field
New growth points in the packaging sector are various types of water bottles that can be re-sterilized and used. Due to its light weight, good impact resistance and transparency, and the advantages of using hot water and corrosive solutions for washing without deformation and maintaining transparency, PC bottles have completely replaced glass bottles in some fields. It is predicted that with the increasing emphasis on the quality of drinking water, the use of polycarbonate in this area will increase at a rate of more than 10%, and it is expected to reach 60,000 tons in 2005.
Sixth, electronic appliances
Due to its good and constant electrical insulation over a wide range of temperature and humidity, polycarbonate is an excellent insulating material. At the same time, its good flame retardance and dimensional stability make it a broad application field in the electronic and electrical industries. Polycarbonate resin is mainly used for the production of a variety of food processing machinery, power tool housing, body, bracket, refrigerator freezer drawer and vacuum cleaner parts. In addition, polycarbonate materials also show extremely high use value for important components such as computers, video recorders and color televisions with high parts accuracy requirements.
Seventh, the use of phosphate flame retardant optical lens
Polycarbonate occupies an extremely important position in this field because of its unique characteristics of high light transmittance, high refractive index, high impact resistance, dimensional stability and easy processing and molding. Optical lenses made of optical grade polycarbonate can be used not only for cameras, microscopes, telescopes, and optical test instruments, but also for film projector lenses, copier lenses, infrared auto-focus projector lenses, laser beam printer lenses, and each The prisms, multi-faceted mirrors and many other office equipment and home appliances have a very wide application market. Another important application area of ​​polycarbonate in optical lenses is as a lens material for children’s eyeglasses, sunglasses and safety glasses and adult eyeglasses. The average annual growth rate of polycarbonate consumption in the world’s optical industry has been maintained at more than 20%, showing great market vitality.
Eight, disc
With the rise of the information industry, optical discs made of optical grade polycarbonate are being used as a new generation of audio and video information storage media and are rapidly developing at an extremely fast pace. Due to its excellent performance characteristics, polycarbonate has become the main raw material for the world’s optical disc manufacturing industry. The amount of polycarbonate consumed by the world’s optical disc manufacturing industry has exceeded 20% of the total consumption of polycarbonate, and its average annual growth rate exceeds 10%. China’s optical disc production has grown rapidly. According to figures released by the State Press and Publication Administration, there were 748 disc production lines nationwide in 2002, which consumed about 80,000 tons of optical grade polycarbonate and were all imported. Therefore, the application prospect of polycarbonate in the field of optical disc manufacturing is extremely broad.
