SABIC, founded in 1976, is the third largest chemical enterprise in the world. As the "exclusive technology gathering place" within SABIC group, special materials division is committed to developing advanced technology, solving industry challenges, and promoting global changes in transportation, communication, work and life.Due to the non crystallinity of polycarbonate, the packing between molecules is not compact enough. The organic solvents of aromatic hydrocarbon and chlorinated hydrocarbon can make it swell or dissolve, which is easy to cause solvent cracking. The alkali resistance is poor.SABIC is the world's leading diversified chemical company, headquartered in Riyadh, Saudi Arabia. SABIC has manufacturing facilities all over the world, including the Americas, Europe, the Middle East and the Asia Pacific region. Its products cover chemicals, general and high performance plastics, agricultural nutrients and steel. SABIC has operations in more than 50 countries around the world, with about 33000 employees, and has set up innovation centers in five key regions, namely, the United States, Europe, the Middle East, Southeast Asia and Northeast Asia, with abundant scientific research resourcesPC electrical properties: polycarbonate has low molecular polarity, high glass transition temperature and low water absorption, so it has excellent electrical insulation performance, which is close to or relative to pet which has been considered as excellent electrical insulation performance. The electrical insulation of polycarbonate is closely related to temperature, humidity, electric field frequency and product thickness.PC耐老化性和耐燃性 聚碳酸酯的耐熱老化性能也相當好,若將其薄膜放置空氣中長時間加熱,其性能變化很小。聚碳酸酯是可燃的,火焰呈淡、冒黑煙;氧指數(shù)僅25%,離開火焰自熄。一般加入鹵化物、三氧化二、氧化、和等改性提高阻燃性。盡管PC具有許多優(yōu)能,然而由于PC分子鏈的高剛性和大的空間阻位使其具有較高的熔體粘度,因此加工困難,易開裂,耐溶劑性和耐磨損性較差,因此對PC改性研究成為PC應用研究重要的課題,目前聚合物合金化成為PC改性重要途徑,國外已有大量性能優(yōu)良PC合金投入市場,隨著PC合金材料的研究不斷進展,PC的應用范圍不斷擴大, PC開發(fā)前景的應用領域,寬波透光的光學器械,作為一種透明性能良好的工程塑料,PC作為光盤基材在全球大量使用, 不僅可以制備CD、VCD、DVD光盤,還可以適用于高密度記錄光盤的基材, PC片材特別適宜于制作眼鏡鏡片,在PC分子鏈中引入硅氧基團,可以提高其硬度及耐擦傷性。PC作為高折射率塑料,用于制作耐高溫光學纖維的芯材
