UV resistant PC 2825 has low water absorption and good transparency

Description :

　　Main advantages of PC:

　　1. High mechanical strength. Its impact strength is one of the highest among thermoplastic materials, even higher than aluminum and zinc, known as the "plastic metal"; High elastic modulus, minimally affected by temperature; Outstanding creep resistance, even at higher temperatures and longer periods of time, the creep amount is very small, better than POM; Other aspects such as toughness, flexural strength, and tensile strength are also superior to PA and other general plastics. The low-temperature mechanical strength of PC is very valuable. So within a wide temperature range, it has strong low-temperature impact resistance, good cold resistance, and a low brittleness temperature of up to -100 ℃;

　　2. Excellent thermal and weather resistance. The heat resistance of PC is higher than that of general plastics, with a thermal deformation temperature of 135-143 ℃,

　　Long term working temperature up to 120-130 ℃, it is a commonly selected plastic for heat-resistant environments. Its weather resistance is also very good. Some people have conducted experiments where PC components were placed outdoors with large temperature changes and exposed to sunlight and rain. After three years, the color was only slightly yellow, but the performance remained unchanged;

　　3. High molding accuracy and good dimensional stability. The molding shrinkage rate is basically fixed at 0.5%~0.7%, and the shrinkage in the flow direction is basically consistent with the vertical direction. High dimensional reliability over a wide range of operating temperatures.

　　Characteristics of PC

　　1. It is hard and resilient, with high impact resistance, high dimensional stability, wide range of operating temperatures, good electrical insulation, heat resistance, and non toxicity. It can achieve the expected effect through injection molding and extrusion molding, so its development is very rapid. Currently, the world's annual consumption has exceeded 300000 tons.

　　2. Polycarbonate is a transparent, slightly or white, rigid and tough polymer. When burning, it burns slowly and then extinguishes slowly after leaving the fire. The flame forms black smoke and carbon bundles. After burning, it melts and foams, emitting a foul odor of flowers and fruits.

　　3. Polycarbonate has excellent performance and good light transmittance, with a transmittance of nearly 90%. The relative density is 1.20, which is larger than polyolefins, smaller than polyformaldehyde and polyvinyl chloride, and similar to polymethyl methacrylate.

　　The three major application areas of PC are glass assembly industry, automotive industry, and electronics and electrical industry, followed by industrial machinery parts, optical discs, packaging, computer and other office equipment, medical and health care, film, leisure and protective equipment, etc. PC can be used as door and window glass, and PC laminated panels are widely used for protective windows in banks, detention centers, and public places, as well as for aircraft cabin covers, lighting equipment, industrial safety barriers, and glass. PC boards can be used for various signs, such as fuel pump dials, car instrument panels, warehouse and outdoor commercial signs, dot type sliding indicators. PC resin is used for car photography systems, instrument panel systems, and interior decoration systems, as front lampshades, reinforced car front and rear bumpers, reflective mirror frames, door frame covers, operating rod sleeves, blocking plates. PC is used as junction boxes, sockets, plugs and sleeves, gaskets, TV conversion devices, communication cable connectors under telephone line brackets, switch boxes, telephone exchanges, distribution panel components, relay housings. PC can be used as low load parts for household appliance motors, vacuum cleaners, hair washers, coffee makers, toasters, power tool handles, various gears, worm gears, shaft sleeves, etc. Guidelines and refrigerator shelves.

　　The purpose of PC:

　　The excellent comprehensive performance of PC makes it occupy an important position in the fields of machinery, instrumentation, automobiles, electrical appliances, textiles, chemicals, food, etc. Finished products include: food packaging, dining utensils, safety helmets, pump blades, surgical instruments, medical equipment, insulation materials, gears, car lamp shades, high-temperature lenses, peephole mirrors, electrical connectors, and laser discs, laser discs, etc.
