Oxidization and yellowing while drying the resins can be avoided by reducing oxygen concentration in a vacuum environment.
Thermal Conduction Vacuum Dryer
Prevent oxidization and yellowing by removing oxygen dissolved in the resin through N2 drying and N2 purge!
Compact Thermal Conduction Dryer + N2 generator
Effective for oxidization and yellowing that cannot be avoided in dehumidification drying of the resin materials.
Nitrogen Dryer (for Optical Materials)
Simply by attaching it to the existing material dryer, yellowing of the molded items can be prevented.
