Polyoxymethylene

POM (Polyoxymethylene) is a linear polymer with no side chain, high density, and high crystallinity. According to the chemical structure of its molecular chain, it can be divided into homoformaldehyde and co-formaldehyde. Homoformaldehyde has high density, crystallinity, and melting point, but poor thermal stability, narrow processing temperature range (about 10°C), and slightly low stability to acid and alkali. The density, crystallinity, melting point, and strength of co-formaldehyde are lower, but the thermal stability is good, it is not easy to decompose, the processing temperature range is wide (about 50°C), and the stability to acid and alkali is good. It is an engineering plastic with excellent comprehensive properties. - Product: POM plastic particles (Polyoxymethylene Resin) - Colour: Natural color, white, black, etc. (customizable) - Grade: Injection or extrusion etc. - Package: Conventional packaging 25kg/bag (customizable) - It is a linear polymer with high density and high crystallinity, and has an obvious melting point. - High crystallinity and large volume shrinkage. - The water absorption of POM is about 0.25%. The presence of water has little impact on its performance and molding process. Therefore, it may not need drying before molding, but it will improve the product when the particle surface absorbs water. From the appearance, it still needs drying. - Resin with high melt mass flow rate has good fluidity. The excellent comprehensive performance makes POM widely used in many fields such as electronic and electrical, automobile, machinery manufacturing, chemical industry, building materials, etc. Characteristics / Technical Specifications: - Material: Polyoxymethylene (POM) - Type: Virgin or recycled - Additives: Glass fiber, conductive, toughening, etc. (customizable) - Grade: Injection or extrusion - Color: Natural, white, black, customizable - Packaging: 25kg/bag, customizable - Applications: Electronics, automotive, machinery, chemical industry, building materials - High density and crystallinity - Good thermal stability (co-formaldehyde type) - Low water absorption (~0.25%) - Good acid and alkali resistance (co-formaldehyde type)
