Material used in frames

The most commonly used plastics in eyeglass frames are cellulose acetate, Kevlar, nylon, cellulose propionate and Optyl. cellulose acetate comes in a wide variety of colors textures and patterns but tends to get brittle with age while cellulose propionate is light weight material that is ideal for intricate designs , overheating will shrink and ruin this material . Kevlar plastics are limited used in cool glasses frames because it will not shrink and it comes in few colors. Nylon plastics are unbreakable so these are mainly used for sports and safety glasses, can be manufactured only in dark colors and become brittle overtime. Optyl material is lightweight than cellulose acetate and is hypo allergic, an advantage to skin allergic.

                                                                Composites of these materials also used like carbon fiber graphite provide the endurance of metal frames and Copolyamide is a blend nylon manufactured for frame injection molding. A material Flexon7 is also available made from titanium based alloy that enable a twisted frame to its original shape. The most desirable material for manufacturing frames is titanium which is non corrosive and fifty percent lighter than most of metal frame material used in cool glasses.
