What plastic is used in sunglass manufacturing
There are quite a few types of materials used for sunglasses manufacturing. Question is, what sort of price are you willing to pay?
Considering you are serious about quality, you can start by looking at Polycarbonate (PC) material. PC sunglasses are made using injection molding and are pretty economical. They can take any colour you wish by using dyes.
TR90 is a marginally better material and also more pricey. A typical consumer can not tell the difference between TR90 and PC, however. This material is also made using injection molding.
