This datasheet of TROGAMID BX7304 nc (nf) from Evonik Industries AG is provided by the international plastics database CAMPUS.
CAMPUS is organized by a group of leading international resin producers, who have agreed to test their material according to uniform conditions, based on ISO standards (ISO 10350, ISO 11403), in order to offer comparable data to the market.
Permanently transparent polymer blend of amorphous (PA6-3-T) and
partially crystalline Polyamide; stress crack resistant, low water absorption.
Application examples: Eyeglasses frames, optical industry,
medical applications, machinery construction.

PREPROCESSING INFORMATION
Maximum Water Content: 0.1 %
When the indicated water content is exceeded, the resin must be dried. The drying time is
dependent on the drying temperature. In practice a drying time of 6-12 hours at a temperature
of 80 - 90°C (depending on the water content of the resin) has been found to be satisfactory.
With the exception of fresh air dryers, all conventional dryers can be used.
PROCESSING INFORMATION
