Evonik's TROGAMID® product group includes base polymers and molding compounds that are distinguished particularly by permanent transparency and high chemical resistance.

Permanently transparent polyamides

TROGAMID® molding compounds combine permanent transparency with good UV resistance, high mechanical toughness, and excellent resistance to chemicals, aggressive lubricants, and cleaning agents. This is why they are in demand in all applications where these properties offer added value, such as inspection glasses for flowmeters, and lenses for sports glasses and sunglasses.

With the takeover of the Chemicals division of Dynamit Nobel AG in 1988, Evonik acquired the transparent, amorphous polyamide TROGAMID^® T. Dynamit Nobel launched this first polymer of dimethyl terephthalate and trimethylhexamethylene diamine on the market as early as 1968. Substitution of the aromatic components by aliphatic monomers led in 1991 to transparent polyamides with inherently better UV resistance. Systematic selection of the cycloaliphatic diamine and 1,12-dodecanedioic acid monomers resulted in a crystallizable, permanently transparent polyamide, distinguished as crystalline by the name TROGAMID^® CX, in 1995.
