Product Texts

Microcrystalline, permanently transparent polyamide

TROGAMID® CX7323 is a microcrystalline transparent polyamide for the manufacture of parts according the injection molding procedure.

The crystallites are so small, that they do not scatter visible light, and the material appears transparent to the human eye. The crystalline structure causes the excellent crack resistance for this polymer.

TROGAMID® CX7323 is supplied as spherical pellets in polyethylene packaging.

Deviations of molds or in processing are possible to a certain extent, if they are required by the cavity or the process itself.

Pigmentation may affect values.

For information about processing of TROGAMID®, please follow the general commendations about “Processing of TROGAMID® compounds”.
