Decomposition can rapidly result in the build-up of a high gas pressure in the barrel of the processing unit. If the die is sealed there may be a sudden release of pressure via the filling hopper. halogenated fire protection agents, must be avoided under all circumstances.

Very free-flowing, rapidly solidifying grade for use where processing is extremely difficult but mechanical properties are lower. Abbreviated designation according to ISO 1043-1: POM Designation according to ISO 29988-POM-K,,M-GNR,5-2
Emission optimized, easy flowing and rapidly freezing grade for injection molding difficult, thin-walled parts. Abbreviated designation according to ISO 1043-1: POM Designation according to ISO 29988-POM-K,,M-GNR,4-2 Processing In order to obtain best emission performance it is recommended to process at comparatively low melt temperatures with pre-dried material. Furthermore avoid high screw speed, high shear and long cycle times. Additional information is available upon request.
