TROGAMID^® T—Polyamide 6-3-T

Low shrinkage

The chemical constitution of TROGAMID^® T, which is produced from terephthalic acid and 2,2,4- /2,4,4-trimethylhexamethylene diamine, gives the polymer its amorphous structure. In contrast to Evonik's semicrystalline high-performance polymers, it is transparent. The transparency is retained even for layers of relatively high thickness. Its light transmission in the visible wavelength range is 90%. Moreover, the amorphous structure results in low processing shrinkage and little tendency to warp.

TROGAMID^® T compounds are distinguished by the following properties:

• high transparency, high light transmission
• high mechanical strength
• high heat deflection temperature
• high toughness
• good chemical resistance compared with other plastics
• good electrical properties
• low processing shrinkage

A number of specially finished molding compounds are available in addition to the basic products. The product range allows a large variety of applications and meets various requirements profiles.

TROGAMID^® T5000, the basic product, is a permanently transparent polyamide for injection molding, extrusion, and blow molding. It contains no additives.

TROGAMID^® T5002, TROGAMID^® T5004, and TROGAMID^® TX7389 are permanently transparent compounds for injection molding, extrusion, and blow molding. TROGAMID^® T5002 and TROGAMID^® TX7389 contain an internal mold release agent, with TROGAMID^® TX7389 having better flow and mold-release behavior.
TROGAMID^® T5004 is UV-stabilized and therefore has improved outdoor weathering resistance.

TROGAMID^® T-GF35 contains 35% glass fibers. This amorphous polyamide is suitable for rigid, low-warpage moldings. If it is mixed with TROGAMID^® T5000, the resulting moldings have lower glass-fiber content, in accordance with the specific application and the required property profile.
