通过选择特定的单体,可以得到结晶的、永久透明的聚酰胺:三唑胺CX。这些晶体非常小,不会散射可见光,而且这种材料对人眼来说是透明的,这就是所谓的微晶性。由于其结晶度,微晶结构保留了重要的特性,如抗应力开裂-无云化。结晶度是可以忽略不计的,但它对成型件的收缩行为没有不利影响。屈氏体cx经历了类似于非晶材料的各向同性收缩。优良的抗紫外性能、高机械强度、永久透明性、高透光性和优异的耐化学性的结合,为三元色谱仪的生产开辟了广阔的应用领域。典型的应用领域包括汽车工业、机械和工程、医疗技术、体育和娱乐业、眼镜生产、化妆品工业以及水处理和过滤技术。TROGAMID CX7323:中等粘性、永久透明的注塑和挤压用聚酰胺 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.
