  • Polycarbonate sheet with improved fire retardant performance
    Patent number: 6649677
    Abstract: It has been discovered that the fire resistance properties of polycarbonate sheet can be greatly enhanced by significantly reducing the viscosity of the resin used to manufacture the sheet. Moreover, the fire resistance of the sheet can be further enhanced by carefully controlling the content of phosphorous-based stabilizer, in combination with the processing release agent, within a specific range.
    Type: Grant
