PC lampshade is a series of lampshades made of PC (polycarbonate) for light bulbs, LED lamps, LED fluorescent lamps, car lamps and lamp housings.

Polycarbonate is a thermoplastic resin with-[o-r-o-co]-link in its molecular main chain. According to the different ester groups in its molecular structure, it can be divided into aliphatic, alicyclic and aliphatic-aromatic types, among which aromatic polycarbonate is of practical value, and bisphenol A polycarbonate is the most important, with a molecular weight of 300,000-100,000.Polycarbonate, English name polycarbonate, referred to as PC. PC is an amorphous, odorless, nontoxic and highly transparent colorless or yellowish thermoplastic engineering plastic, which has excellent physical and mechanical properties, especially excellent impact resistance, high tensile strength, bending strength and compressive strength. Small creep and stable size; It has good heat resistance and low temperature resistance, stable mechanical properties, dimensional stability, electrical properties and flame retardancy in a wide temperature range, and can be used for a long time at -60~120℃; It has no obvious melting point and is in a molten state at 220-230℃. Due to the high rigidity of molecular chain, the viscosity of resin melt is high; Small water absorption, small shrinkage, high dimensional accuracy, good dimensional stability and low film permeability; It is a self-extinguishing material; Stable to light, but not resistant to ultraviolet light, good weather resistance; Oil-resistant, acid-resistant, alkali-resistant, oxidizing acids, amines and ketones, soluble in chlorinated hydrocarbons and aromatic solvents, easy to cause hydrolysis and cracking in water for a long time, with the disadvantages of poor fatigue strength, easy stress cracking, poor solvent resistance and poor wear resistance.

PC(Polycarbonate) is the abbreviation of polycarbonate or polycarbonate, or PC engineering plastics for short. In fact, PC material is one of the engineering plastics. As a widely used material in the world, PC has its own characteristics and advantages and disadvantages. First of all, PC is an amorphous thermoplastic resin with excellent comprehensive properties, with excellent electrical insulation, ductility, dimensional stability and chemical corrosion resistance, high strength, heat resistance and cold resistance; It also has the advantages of self-extinguishing, flame retardant, non-toxic and colorable. You can see the shadow of PC plastic in every corner of your life, and its large-scale industrial production and easy processing make it extremely cheap. Its strength can meet all kinds of needs from mobile phones to bullet-proof glass. The disadvantage is that it is not hard enough compared with metal, which makes its appearance easier to scratch. However, its strength and toughness are good, and it has a long life regardless of heavy pressure or general beating.
