High Flow, Wear resistant PC Pellets

PC raw material resin, its outstanding performance is high impact resistance, small lateral shrinkage, excellent dimensional stability of the product and low creep resistance, and the temperature resistance is above 120 degrees Celsius, and it can operate at a high temperature of 100~110 degrees Celsius for a long time, and Environmental protection meets the requirements of ROHS. Among the five general-purpose engineering plastics, the transparency is relatively the best in the medium term, and the coloring property is excellent. It is suitable for all kinds of products. Due to the outstanding comprehensive performance of PC raw materials, it is often used in auto parts, fireproof electronic equipment casings, optical disc materials, aerospace fields, mobile office supplies, construction consumables, packaging and medical fields, etc.

High fluidity PC--The transmittance of ordinary PC materials is generally about 88%, but the transmittance of its highly transparent PC materials can reach 90%~92%. The optical field occupies a very broad market space, and because of its thermal deformation and good dimensional stability, it can produce high-precision optical materials. Among them, the PC share of ordinary eyeglass lenses has been stable at an annual growth rate of more than 20%, and It shows a growing trend. Today, the high-fluidity PCs developed by major PC manufacturers can reach a melt index of more than 100, which is suitable for very thin-walled products, and can be as low as 0.3mm. Typical applications include the optical disc industry.

High fluidity PC-PC raw material has high impact resistance, heat distortion temperature above 120 and excellent UV resistance (suitable for outdoor), and its low odor can be used in the development and application of auto parts. Because this material can be used at a wide range of temperatures of -40 degrees and 180 degrees, it has excellent electrical insulation; at the same time, the flame retardant level of this material can reach the level of 1.5mmV0, which makes it widely used in the electronic and electrical industry. application. Polycarbonate sheet has good light transmission, impact resistance, UV radiation resistance and dimensional stability of its products and good formability, which makes it have obvious technical performance advantages over inorganic glass traditionally used in the construction industry.
