  • Polycarbonate solid surface composition
    Patent number: 6696509
    Abstract: The present invention comprises a polycarbonate solid surface product through utilization of polycarbonate flakes. The polycarbonate flakes offer unique shapes and improved ultra-violet stability to the product. The polycarbonate flakes are also a source of consistent clear particulate and provide for increased mechanical properties in some areas over prior art 100% polyester products. Additional, fire retardant polycarbonate offers fire retardancy in a clear chip unlike opaque ATH filled polyester chips, or UV sensitive polyester that has been halogenated.
