Black POM\/Polyformaldehyde<\/span><\/h2>\n

The scientific name for polyformaldehyde is also known as POM or special steel. Polymerized with formaldehyde as a raw material.<\/span><\/p>\n

Black POM Advantages<\/span><\/h2>\n

1. Good physics, mechanical and chemical performance, especially will excellent wear resistance.<\/span><\/p>\n

2. Polyformaldehyde is a high-density crystalline polymer without a side chain and has excellent comprehensive properties.<\/span><\/p>\n

3. Polyformaldehyde is a kind of hard and dense material, with a smooth surface, shiny, light yellow, or white, and can be used at -40-100\u00b0C for a long time.<\/span><\/p>\n

Black POM Physical Property<\/span><\/h2>\n

Polyformaldehyde tensile strength is 70MPa, \u00a0low water absorption, and the size is stable and gloss. Its properties are better than nylon. Polyformaldehyde is a highly crystalline resin and is the strongest of thermoplastic resins. It possesses high heat resistance, high bending strength, high fatigue resistance, excellent wear resistance, and electrical property.<\/span><\/p>\n

Black POM Plasticity Feature<\/span><\/h2>\n
    \n
  • POM is also used for pipe equipment (pipe valve, pump shell), lawn devices, etc., because of its high-temperature resistance.<\/span><\/li>\n
  • POM is a kind of strong and elastic material, even at low temperatures, it still has good crystallization index resistance, great stability, and impact resistance.<\/span><\/li>\n
  • The high crystallinity of POM leads to a high shrinkage rate which up to 2%\u4e003.5%. \u00a0And different reinforcement materials have different shrinkage rates.<\/span><\/li>\n
  • Decomposition occurs when the temperature exceeds a certain limit or when the melt is heated for too long. POM has a good comprehensive performance. It is the hardest thermoplastic.<\/span><\/li>\n<\/ul>\n

    Black POM\u00a0Chemical Property<\/span><\/h2>\n

    According to the different molecular chain structures, poly (formaldehyde) qi Run plastic can be divided into homogeneous poly (formaldehyde) and copolymer poly (formaldehyde).<\/span><\/p>\n

    Disadvantages:\u00a0 Very limited resistance to acid, strong alkali, and ultraviolet radiation. (Adding UV agents can greatly improve its UV resistance).<\/span><\/p>\n
