Recently, U.S. companies have developed and manufactured a special high-temperature flame retardant for PC, which has the following characteristics:
1. It does not contain bromine and chlorides, has high solubility in PC, and has a small amount, is easy to process, and has no specific requirements for material production and processing technology;
2. V0 flammability rating can be achieved when 1% is added;
3. Do not need to granulate, direct molding after mixing, especially suitable for transparent pc applications;
4. Through the use of general-purpose Pc resin, adding this flame retardant to achieve the use of pc flame retardant special materials;
5. Users can save a lot of cost;
6. Higher flame retardant requirements can be achieved by adding anti-low-strength flame-retardant synergists. At this time, extrusion granulation is required and the parts are not transparent. If the user has conditions for self-granulation processing, the cost can be saved by about 2,000 yuan per ton.
