Are All Raw Materials In Plastic Sunglasses Frames The Same?
The answer is a resounding, NO - All raw materials in plastic sunglasses are NOT the same. As with most products there is the cheap and easy way then there is the right way. Lesser quality plastic frames made from Propionate for example lose their original shape over time with very little outside influence. In addition Propionate sunglasses frames melt in severe heat (think inside hot car) and freeze & crack in extreme cold conditions. Beware of sunglasses frames made of low end plastics especially for extreme outdoor and safety applications the materials are for sure a difference maker.
