Crocs material croslite
Croslite is a patented closed resin material that is neither rubber nor plastic.
For reference, the discoloration principle of sunglasses:
1 Sunglasses lens materials and functional sunglasses lens materials mainly include glass materials and [resin materials].
2 There is one type of lens classification - gt; photochromic lens: the color can change according to the intensity of ultraviolet rays in the sun and changes in ambient temperature.
3 The principle of photochromic lenses is to add photochromic factors to the lenses: Silver bromide particles are generally added to glasses, and silver bromide will decompose into bromide ions under ultraviolet irradiation. With silver ions, silver ions appear black. With the intensity of ultraviolet rays, the degree of decomposition is also different. When indoors, the intensity of ultraviolet rays weakens, and bromide ions and silver ions will be converted into silver bromide. This is a reversible reaction. In addition to adding silver bromide raw materials to the lens, In addition, some catalysts must be added to ensure the balance of chemical reactions and some colorants to make the lenses have different colors. It seems that we have learned something. I think this shoe can either achieve more complex changes or color combinations through chemistry, or other color changing factors may be used.
