In recent years, the research on flame retardant technology and the development and application of flame retardant products have attracted attention from all walks of life. China's fireproof material technology has also been greatly improved, especially in green, new and high-tech fireproof materials. Progress, the comprehensive performance of fire-resistant materials has been greatly improved. Today, Xiaobian takes everyone to discuss the types of commonly used PC flame retardants and their work efficiency.

Current PC flame retardants are mainly divided into bromine, organic phosphorus, silicon, sulfonate and boron. The amount of bromine flame retardants added is relatively large: generally about 10% -30%, and most decomposition temperatures are relatively low. Organophosphorus flame retardants are generally used in PC / ABS alloys. The boron-based flame retardant is usually used in combination with polysiloxane to achieve a better flame retardant effect. Xanthate flame retardants have higher efficiency. PC has reached UL 94 V-0 level with very little addition. If you want to achieve higher flame retardant properties, you need to use them with other flame retardants. Although PC itself has certain flame retardancy, in order to improve its flame retardancy, we can modify the flame retardant of PC. PC flame retardant has significant characteristics and advantages such as high active purity, high flame retardant efficiency, low addition amount, and good dispersibility. It is especially suitable for PC / ABS alloy flame retardant systems. It can be added alone or in combination. More prominent.
