Polycarbonate (PC) has been widely used in home appliances, automobiles, electronic appliances and other fields due to its excellent optical transparency, excellent impact resistance and heat resistance. In today’s era of rapid technological advancement and constantly improving quality of life, consumers have increasingly stringent requirements for aesthetics and safety, which also puts higher standards on the transparency and flame retardant properties of PC materials.
As the concept of environmental protection is increasingly popular, relevant laws and regulations are also being strengthened. For example, in recent years, the EU’s restrictive policies on perfluorinated or polyfluoroalkyl substances (PFAS) have been continuously tightened. The European Chemicals Agency (ECHA) has proposed a ban on the production and use of PFAS, and the development of more environmentally friendly flame retardant systems is imminent.
Adhering to the mission of “chemistry, making life better”, Wanhua Chemical has developed a new environmentally friendly flame retardant system without bromine, chlorine and PFAS restricted substances for different use scenarios based on adjusting the molecular structure of traditional polycarbonate with its unique material technology and production technology. It has launched the Clarnate® transparent flame retardant series PC material – FR3730T & FR3730H, which has the following unique performance advantages while ensuring the same performance as ordinary PC products in terms of light transmittance, haze, etc.
The Clarnate® transparent flame retardant series of PC products has achieved mass production, providing downstream customers with a variety of flame retardant grades of PC materials ranging from 1.5mmV0 to 3.0mmV0. This feature has made it widely favored and recognized in many fields such as electronics and electrical appliances, optical lighting, and rail transportation.
In the future, Wanhua Chemical will continue to devote itself to the research and development of high-performance materials with the concept of continuous innovation, and will strive to launch higher-demand transparent flame-retardant PC materials to meet the diverse needs of the market and continuously promote the development and progress of the industry
