Evonik TROGAMID® CX9704 Polyamide
Categories:	Polymer; Thermoplastic; Acrylic (PMMA)
Material Notes:	Properties: Common transparent polyamides consist in partially aromatic units that impart rigidity and high heat resistance. Our TROGAMID® T5000 is a typical representative of this group. Replacing aromatic constituents with aliphatic monomers improves the UV stability of transparent polyamides. TROGAMID® CX7323 is an example of this type of polyamides. 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. TROGAMID® CX combines the chemical resistance of semi-crystalline molding materials with the advantages of amorphous, UV-resistant materials. The outstanding properties of TROGAMID® CX are: crystal-clear, permanent transparency, high transmission superior chemical and stress cracking resistance high level of UV resistance low water absorption compared with many other polyamides, which leaves the mechanical properties virtually unaffected very balanced mechanical property profile high dimensional stability high impact resistance, even at low temperatures high level of dynamic strength (e.g., for internally pressurized parts) abrasion and scratch resistance high glass transition temperature very low isotropic shrinkage easy processing 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 auto motive industry, machinery and engineering, medical technology, the sports and recreation industry, the glasses production, the cosmetics industry and in water treatment and filter technology.
