Product Description

Polycarbonate (PC) is a carbonated polyester. Carbonic acid itself is not unstable, but its derivatives (such as light gas, urea, carbonate, carbonate) have a certain stability. According to the different alcohol structure, polycarbonates can be divided into lipids and aromatics. Lipid polycarbonate. For example, polyethyl carbonate, polysanyl methyl carbonate and its copolymers have low melting point and vitrification temperature and poor strength, and cannot be used as structural materials; however, using their biocompatibility and biodegradability characteristics, they can be applied in drug slow-release carriers, surgical sutures, bone support materials, etc. Polycarbonate is resistant to weak acid, weak alkali and neutral oil. Polycarbonate is not resistant to ultraviolet light and strong alkali. PC is a linear carbonated polyester. The carbonate groups in the molecule are alternated with other groups, which can be aromatic, aliphic, or both. Bisphenol A-type PC is the most important industrial product. PC is an almost colorless glass-like amorphous polymer with good optical properties. PC high molecular weight resin has high toughness, the impact strength of the cantilever beam notch is 600~900J/m, and the thermal deformation temperature of the unfilled grade is about 130°C. After glass fiber reinforcement, this value can be increased by 10°C. The bending modulus of PC can reach more than 2400MPa, and the resin can be processed into large rigid products. Below 100°C, the creep rate under load is very low. PC has poor hydrolysis resistance and cannot be used for repeated products that have been subjected to high-pressure steam. Polycarbonate The main performance defects of PC are that the resistance to hydrolysis is not high enough, it is sensitive to notches, resistant to organic chemicals, has poor scratch resistance, and will turn yellow when exposed to ultraviolet rays for a long time. Like other resins, PC is easily eroded by certain organic solvents. PC materials are flame retardant. Antioxidant.

Polycarbonate is colorless and transparent, General Grade Polystyrene heat-resistant, Polyamide impact-resistant, flame-retardant BI-level, and has good mechanical properties in normal use temperature. Compared with the performance close to polymethyl methacrylate, polycarbonate has good impact resistance, high refractive index, good processing performance, and UL94 V-2 flame retardant performance without additives. However, the price of polymethyl methacrylate is lower than that of polycarbonate, and large-scale devices can be produced by ontological polymerization. The wear resistance of materials is relative. If you compare Abs Material with PC material, it means that PC material has better wear resistance. However, compared with most plastic materials, the wear resistance of polycarbonate is relatively poor, which is at the lower middle level, so some polycarbonate devices used for easy-to-wear purposes require special surface treatment. Classify Anti-static PC, conductive PC, fiber-added fireproof PC, anti-ultraviolet and weather-resistant PC, food-grade PC, chemical-resistant PC.
