PC 6487 bair properties: physical properties PC is a kind ofamorphous engineering material, which has particularly good impactstrength, thermal properties, gloss, properties, flame retardantproperties and pollution resistance. The otched Izod impact stregthof PC is very high, and the shrinkage rate is very low, generally0.1%~0.2%.Chemical properties PC has good mechanical properties,but poor flow characteristics, so this material injection is moredifficult. In the selection of what of PC materials, to theend of the product expectations as a benchmark. If the plasticrequires a high impact resistance, then the use of low flow rate ofPC materials; Instead, a PC material with a high flow rate can beused, which allows for injection molding. PC plastic raw materialit is a new kind of thermoplastic plastic, the degree of 90%, knownas the metal. It is rigid and ductile, with high impact strength,high size and a wide range of temperature, good electricalinsulation and heat resistance and performance, can be injected,extrusion molding. PC plastic thermal performance, can be in -long-term use of between 100 ℃ to 130 ℃, the brittle temperatureunder - 100 ℃.Although the polyester has poor cracking resistanceand tolerance, easy hydrolysis at high temperature, poorcompatibility with other resins and poor performance, it can bemodified by adding other resins or inorganic filler, so as toachieve excellent performance.
Optical lighting: used for manufacturing large lampshades,protective glass, left and right eyepiece tubes of opticalinstruments, etc. It can also be widely used in aircraft materials.Electronic appliances: poly ester is a good grade E (120 ℃)insulation materials, used in the manufacture of connectors, coilframework, pipe insulation, insulation casing, telephone shell andparts, miner's lamp battery shell, etc. It can also be used formaking parts with high dimensional accuracy, such as optical disc,telephone, electronic computer, video recorder, telephone switch,relay and other communication e Polyurethane thin touch isalso widely used as capacitors, insulation bags, tapes, color videotapes and so on.Mechanical e: used for manufacturing allkinds of gear, rack, worm gear, worm, bearing, CAM, bolt, lever,crankshaft, ratchet wheel, also can be used for some mechanicalparts, cover and frame parts.E: cups, tubes, bottles,dental instruments, containers, surgical instruments, and evenartificial organs such as artificial lungs.Other aspects: doublewall panels with hollow reinforcement, glass for the greenhouse,etc. Used in textile industry as textile yarn tube, textile machinebearing bush, etc. Daily use for milk bottles, tableware, toys andmodels, etc.
