Transparent polyamides are broadly established in the technically demanding fields of automotive, electronics and constructions. The TROGAMID® CX family combines the transparency and processing behavior of amorphous materials with the advantages of polyamides like toughness, rigidity, abrasion resistance, and chemical and stress cracking resistance. When special aliphatic and cycloaliphatic monomers are used, transparent polyamides can be made that have inherently better UV resistance, like TROGAMID® CX9704. In addition, carefully selected monomers yield a crystallizable polyamide, such as TROGAMID® myCX, a PA PACM 12. The crystallites are so small that they don’t scatter visible light. This makes the material appear transparent to the human eye—a property known as microcrystallinity. TROGAMID® CX9704 is the perfect choice for the manufacturing of spectacle frames. It makes possible:- freedom of design in shape and color
- ultra thin frame constructions
- light weight eyeglass frames
- durability, robustness and flexibility
In contrast to other transparent amorphous materials, the microcrystalline TROGAMID® myCX demonstrates excellent stress-cracking resistance. It is an unparalleled transparent material that combines the properties of a semi-crystalline molding compound with those of amorphous materials. For lenses that satisfy the most demanding customer, TROGAMID® myCX is preferred because it:- provides the highest comfort due to its very low weight
- offers excellent optical properties
- delivers the highest safety level possible in sunglass lenses
- can be combined with all potential
- frame materials
- assures highest durability in top quality sunglasses
- prevents crack formation by stress or chemical attack
