Trogamid® compounds are distinguished by permanent transparency and high chemical resistance. Trogamid T grades comprise the amorphous products based on polyamide 6-3-T only, while Trogamid BX grades cover PA 6-3-T blends containing other semicrystalline or amorphous polyamides. The Trogamid CX series includes the crystal-clear specialty polyamides PA PACM 12. These UV-resistant materials are said to combine the resistance to chemicals and stress cracking of semicrystalline plastics with the mechanical advantages of amorphous compounds. In addition, all grades are characterized by high resistance to dynamic loads, proven by Trogamid T5000 and Trogamid CX for many years, for example, in water treatment and filter applications. Here, water filter units prevent corrosion phenomena by restraining the build-up of residue in pipes, especially in building plumbing. Water filters are often used in combination with pressure reducers. Such a control system produces water pressure that is constant and thus gentle on fittings and pipe systems. High requirements are placed on the mechanical and dynamic properties of the materials used in filter units to ensure that the units will not break and cause water damage. Current safety provisions for filter cups specify that the material must withstand internal pressure at least three times the operation pressure. Trogamid compounds are said to be ideal for this application because they fulfill the requirements in short-time stress as well as in dynamic load. In addition, they feature transparency and a high degree of resistance to chemicals and most oils and greases.
