AREAS OF USAGE / It is a plastic obtained by polymerization of formaldehyde. The highly crystalline structure of oxygen and methylene groups in it provides high hardness and durability even without adding any reinforcement material or structure. Resistant to hot water, common organic solvents, petroleum products and most mineral oils. Elasticity (springing), hardness, dimensional stability, high resistance to loads and impacts, excellent abrasion resistance, high mechanical strength and rigidity, bearing properties in oil-free environments, good electrical and insulation properties, low absorption (water absorption) properties, heat resistance Polyoxymethylene' It is one of the important features that distinguishes i from other plastics.
