High heat resistant PC plastic is a kind of polymer plastic that we all encounter and use in our daily life. It is a part of synthetic resins. Because of its excellent properties, it has become a relatively common engineering material in engineering. Today we will briefly introduce some knowledge of high heat resistant PC plastics.

First of all, let's take a look at some of the physical properties of high heat resistant PC plastics. The density of this PC plastic raw material is between 1.18 and 1.12 grams per cubic centimeter. When the temperature is below minus 45 degrees, or above 135 degrees Celsius above zero, the PC raw material will be deformed. Based on these properties of PC raw materials, if it is used at ordinary room temperature, it is said that its performance is still very stable and very useful. If it is used outdoors, it is necessary to add some other chemical components to enhance its stability and heat resistance.

According to the different scope of use of this high heat resistant PC plastic raw materials, it can be divided into several categories, 1, can be divided into anti-static PC raw materials, the second category can be made into conductive PC raw materials. Also, it can be made into a fireproof PC raw material, if it is outdoors, it can be made into a UV resistant PC raw material with low climate requirements, and even a PC raw material for food. It can be said that on the basis of his original performance, it is still very widely used by adding other methods.

The performance of this high heat resistant PC plastic raw material is still very good. It has relatively high light transmittance, easy dyeing, high impact resistance, relatively fixed and so on. These characteristics are a very important reason why it is widely used in the field of general engineering.

High transparent high temperature resistant PC raw material resin, its outstanding performance is high impact resistance, small horizontal shrinkage, excellent dimensional stability of the product is small creep resistance, while the temperature is above 120 degrees Celsius, can operate at a high temperature of 100~110 for a long time, and environmental protection meets the requirements of ROHS. In the five general engineering plastics medium-term transparency is relatively good, excellent coloring, suitable for a variety of products, due to the development of the domestic economy, this PC to oh is also a very fast growth rate. Due to the outstanding comprehensive performance of Pc raw materials, it is often used in auto parts, fireproof electronic equipment shells, optical disc materials, aerospace, mobile office supplies, building supplies.

At present, according to the annual output, the main producing areas of PC resin particles are concentrated in the United States, Europe and Japan. The total annual reserves of these three major producing areas account for about 90% of the world's total PC production. One is the concentration and monopoly of high-end PC materials. The production capacity of four major companies such as Bayer, GE(now the basic innovation company), Dow Chemical and Teijin Co., Ltd. accounts for about 80% of the world's total production capacity. And the production technology of high-performance PC materials in some cutting-edge fields is also mainly mastered by these companies, which jointly dominate and lead the PC raw material market. Second, the development of industrial production in Asia, especially the development of China, the demand for PC raw materials is gradually increasing, and the demand for engineering plastics is becoming more and more strong, so some large manufacturers have begun to slowly focus on the production layout planning in the Asia-Pacific region.

In recent years, due to the continuous development of China's economy, especially the sharp demand in the field of IT electronics and the strong demand in the future pillar industry automotive field, coupled with the demand for raw materials in the western urban development and construction infrastructure, statistics show that China's demand for PC raw materials is growing rapidly in the Asia-Pacific region. Data fully show that in recent years, the annual growth rate of China's demand for polycarbonate has been maintained at about 15%, and in 2005 it reached about 700,000 tons of demand. Among them, 170,000 tons of IT electrical appliances, 100,000 tons of transparent sheets and plates, 40,000 tons of optical discs, 30,000 tons of pure buckets, and about 20,000 tons of lighting and its aviation parts. The driving force of its rapid growth is mainly from China, and it is expected that the domestic Pc demand will reach about 800,000 t in 2006.

High temperature resistant PC plastic -PC material ordinary transmittance is generally about 88%, but its highly transparent PC material its transmittance can reach 90%~92%, combined with its high refraction and high impact resistance characteristics, so that it occupies a very broad market space in the optical field, and due to its thermal deformation and good dimensional stability and other characteristics, can produce high-precision optical materials, Among them, the PC share of ordinary eye lenses has been stable at an annual growth rate of more than 20%, and showing a growing trend, today, like the high mobility PC developed by major PC manufacturers, the melt index can reach more than 100, suitable for very thin-walled products, can be as low as 0.3mm, typical applications include the optical disc industry, At the peak in 2002, China had a total of 750 optical disc production lines in the country, with a consumption of 80,000 tons. Due to the immaturity of current domestic technology, these special materials mainly rely on imports.

High temperature resistant PC plastic -PC raw materials have high impact resistance, thermal deformation temperature above 120 and excellent UV resistance linearity (suitable for outdoor), and its low odor characteristics can be used for the development and application of automotive parts. With the active demand for domestic vehicles in China in recent years, the application of PC materials in this field has great potential for expansion. Because this material can be used at a wide range of temperatures of -40 degrees and 180 degrees, electrical insulation is excellent; At the same time, the flame retardant level of this material can reach the level of 1.5mmV0, so that it has been widely used in the electronic and electrical industry. Polycarbonate sheet has good light transmission, impact resistance, resistance to ultraviolet radiation and the dimensional stability of its products and good molding processing, so that it has obvious technical performance advantages than the inorganic glass traditionally used in the construction industry.
