TROGAMID® T—Polyamide 6-3-T
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
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 requirement profiles.
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
These permanently transparent compounds are also suitable 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.
This amorphous polyamide compound contains 35% glass fibers. It 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.
