Polyoxymethylene (POM), is a highly crystalline polymer that is known for its high flexural and tensile strength, stiffness, hardness, and excellent chemical resistance. It also has a low coefficient of friction, and good heat and fatigue resistance, but insufficient flame resistance.There are two grades of POM, known as Homopolymers and Copolymers. Homopolymers tend to have higher crystallinity levels. Hence they have better short term mechanical properties — stiffness, tensile strength, impact resistance and initial creep resistance. Copolymer grades have better oxidation resistance and exhibit better resistance to creep and creep rupture at longer time scales. Surprisingly, glass fibre filled copolymer grades have better mechanical properties than the corresponding homopolymer. This is because the slightly different chemical structure gives better coupling to the glass fibre.

grades are supplied in pellet form and packed in moisture proof 25 kg multi-layer bags. Other forms of packing like octabins and big-bags with PE or Aluminum in-liners are also available.
All packaging is tightly sealed and should be opened just before processing. It is also advised to be kept in dry environment below 50°C while protected from UV-light. In order to prevent condensation, packaging stored in cold areas should be allowed to warm up to room temperature before being opened.
Under normal conditions is not a toxic and hazardous material. During processing, necessary preventive actions should be held in case of contact with polymer melt or inhalation of the gases. Processing temperatures above 240 °C should be avoided. Detailed safety information can be found in our material safety data sheets (MSDS).
