Overview
Kormax Acetal [technical name Polyoxymethylene] generally comes in either natural white or black colour. Acetal material has low moisture absorption [stable in humid environments], excellent machinability and its FDA compliance allows for direct contact with food stuffs. The black has improved UV resistance and is the preferred choice for outdoor / applications in direct sunlight. It has good dimensional stability but should not be used in temperatures operating above 90°C.
