JiaYu Optical products knowledge: PC lens
PC,which is Polycarbonate, is the thermoplastic resin of which the main chain molecules containing—[O-R-O-CO]—, according to the different ester groups in the molecular structure, it can be divided into aliphatic,alicyclic and aliphatic aromatic types. Among them,aromatic polycarbonate has practical value, bisphenol-A polycarbonate is the most important. It is a kind of thermoplastic engineering plastics with high mechanical, optical, electrical and thermal properties. Suitable for a variety of applications, such as household appliances, automotive lamps, medical devices and packaging containers. And the development of the optical disc industry, but also widely used in the lens industry, so next, let us show you PC material’s variety of characteristics.
From the chemical point of view, PC material is almost colorless glass amorphous polymer,with good optical properties, and PC high molecular weight resin has a good toughness, with flame retardant, wear resistance, oxidation resistance and other properties. From the physical point of view, PC material are colorless and transparent, heat resistant, impact resistant,flame retardant grade BI, and have excellent mechanical properties, impact resistance, high refractive index, good processing performance,etc.
PC material has high strength and elastic coefficient, high impact strength, wide range use of temperature, high transparency and free dyeing, low shrinkage, good dimensional stability, good fatigue resistance,good weather resistance,excellent electrical properties; odorless, harmless to the human body in the line with health and safety and other multiple advantage.
The processing method of PC needs to go through the drying treatment of raw materials to ensure that the raw materials are uniformly colorless,without silver wires,without bubbles and other undesirable conditions,in the future updates we will introduce the lens injection equipment please looking forward to it.
The raw material of PC lens is solid, It is the lens of heat and injection. PC is commonly known as bulletproof glass, therefore the pc lens is super impact resistance , that’s why it’s called the safety lens. The specific weight is only 2 grams per cubic centimeter, because of high refractive index and light specific gravity,greatly reduce the weight of the lens, currently it is the lightest material used in the lens.
