< , Carbonate can be divided into a series of grades according to functional characteristics, such as general grade Transparent grade, medical and food grade, flame retardant, heat-resistant, cold-resistant, weather-resistant, lubricated, glass fiber reinforced inorganic filled electromagnetic shielding, anti-static and composite grades.
< , Each grade can be further subdivided into more specific grades based on the resin melt index or the different components of the mixed modified additives.
< , Some large manufacturers can provide dozens of grades and hundreds of brands of products. The application and development of polycarbonate is developing in the direction of high-composite and high-function specialization and serialization. At present, various special grades and grades have been launched for various products such as compact discs, automobiles, office equipment, box packaging, medical lighting films, etc.
< , Polycarbonate sheets have good light transmittance, impact resistance, ultraviolet radiation resistance, dimensional stability of products and good molding and processing properties.
