| By selecting specific monomers, one can achieve a crystallizable and permanently transparent polyamide: TROGAMID® CX. The crystallites are so small that they do not scatter visible light, and the material appears transparent to the human eye—a property known as microcrystallinity. Because of its crystallinity, the microcrystalline structure retains important properties such as stress cracking resistance — without clouding. The degree of crystallinity is so negligible, however, that it has no adverse effect on the shrinkage behavior of molded parts. TROGAMID® CX undergoes a similar isotropic shrinkage like amorphous materials. The combination of good UV resistance, high mechanical strength, permanent transparency, high transmission and superior chemical resistance opens a wide range of applications for TROGAMID® CX. Typical areas of application are in the automotive industry, machinery and engineering, medical technology, the sports and recreation industry, the glasses production, the cosmetics industry and in water treatment and filter technology.
