Sunglasses frame material, which has several

In the choice of glasses, face an array of counter glasses, often hear the salesperson told us about the titanium frame, alloy frame “and the like. At this time, we will feel very confused. The reality is as large as the knowledge of Ray Ban Outlet glasses frame material, we know very little or nothing. So, from now on, we have to replenish their precious eyes this course. First of all, we have some basic understanding of the material of the frame. (Recommended reading: What are the characteristics of the resin aspheric?)

Sunglasses frames are usually the following materials:

1, Polycarbonate: PC material for short, specific gravity 1.2, not combustion, odorless, non-toxic resin, in line with the provisions of the FDA and the United States Drug Administration, which is characterized with PC lens.

2, propionate, cellulose lipid: Acronym CP material having appropriate elasticity, toughness; can be dissolved in the solvent to form a shaped, so the material should be avoided contacts, acetone, water and an organic solvent such as bananas; CP material is not easily oxidized in the atmosphere, the decomposition, aging, not combustion, its plasticity, good liquidity, processing and coloring methods varied, rich and varied colors can be made. Stability based on the CP.

3, epoxy resin: also called EP plastics, heat resistance, 30% lighter than ordinary plastic, high strength, high hardness, good elasticity can be made thin and light Cheap Ray Ban Sunglasses frame. At the same time has a special memory function, it is also known the memory plastic used to make the senior frames, mirror feet.

4-manganese-nickel alloys: manganese, nickel alloy, manganese-nickel alloy as the main alloying element having good mechanical strength and corrosion resistance.

5 titanium materials: titanium o in the process of heating when the temperature exceeds 860 degrees o its molecular structure will change o the formation of beta titanium. beta titanium-density structure is better than titanium o flexible than titanium metal, its price is 3 times the titanium u o a higher hardness than titanium technology X process difficult and cumbersome than the titanium metal.

6. TR -90 materials (imported from Switzerland toughness memory resin material): super toughness: Cheap Ray Bans frames exercise to prevent deformation or fracture, to protect the face from injury. Memory function: Special memory function, resistance to deformation index of 620kg/cm2. Light quality: 30% lighter than sheet TR-90, can effectively reduce the weight of the glasses more comfortable to wear. Impact resistance: effectively resist external shocks, is more than two of the plate.
