Polycarbonate is an organic combination of rigidity and toughness. Its light transmittance is about 90%, close to glass but lighter than glass, not brittle, and easy to process. Pure polycarbonate can pass a certain level of fire test without adding any flame retardant. With a small amount of flame retardant, polycarbonate can achieve the highest level of fire protection. Polycarbonate can be used up to 120 to 130 degrees.
Polycarbonate is a polymer having a carbonate group in a molecular chain, and can be classified into aliphatic, aromatic, aliphatic-aromatic and the like depending on the structure of the ester group. Among them, the aliphatic and aliphatic-aromatic polycarbonates have low mechanical properties, which limits their application in engineering plastics.
Material characteristics: high strength, low molding shrinkage, poor fatigue resistance, odorless and odorless, harmless to the human body, various processing methods, perfect transparency, adjustable hardness, high temperature resistance, recyclable,
PC can be injection molded, extruded, molded, blow molded, thermoformed,
Printing, bonding, coating and machining,
The most important processing method is injection molding.
Cosmetics application: PC plastic has the characteristics of transparency and material sturdiness, so it is often used as a transparent cosmetic case, cover, cover and other packaging materials.
PC can be repeatedly used repeatedly, PC recyclable mark rating is 7
