Three tips on PC/ABS plastic materials
　　The first point: PC/ABS plastic materials are commonly called polycarbonate, and the English name of polycarbonate is Polycarbonate. It is a general term for a class of polymer compounds containing carbonates in the molecular chain and various materials prepared on the basis of it.
　　 The second point: PC/ABS plastic raw material is a new type of thermoplastic with a transparency of 90% and is known as a transparent metal. It is rigid and resistant, has high impact strength, high standard stability and widely planned operating temperature, excellent electrical insulation function, heat resistance and non-toxicity, and can be injected and extruded. The thermal function of PC plastic is excellent, it can be used for a long time between -100℃-130℃, and the embrittlement temperature is below -100℃. Although polycarbonate has poor resistance to cracking and chemical resistance, high temperature and easy hydrolysis, poor compatibility with other resins, and poor lubricating function, it can be modified by participating in other resins or inorganic fillers to obtain a Excellent function.
　　They are widely used in: Optical lighting: used to make large lampshades, protective glass, left and right eyepiece tubes of optical instruments, etc., and can also be widely used in transparent materials on airplanes. It can be used to make parts with high standard precision, such as optical discs, telephones, electronic computers, video recorders, telephone switches, signal relays and other communication equipment.
　　 The third point: the origin of PC/ABS plastic raw materials. Generally, plastic raw materials come from petrochemicals made of petroleum or natural gas, which is a polymer resin obtained through polymerization.
　　Plastic definition: A polymer compound with synthetic resin as the primary component.
　　 Macromolecule: molecular weight﹥10000;
　　Middle molecule: 1000≤molecular weight≤10000;
　　 low molecular weight: molecular weight <1000;
　　 The three shapes of plastic: glass state; highly elastic state; viscous flow state; instead of solid, liquid and gaseous, it is impossible to have liquid and gaseous.
