POM Sheets

Product description:POM full name is Poly oxy methylene also known as Acetal,Website:http://www.noves-china.com, poly acetal and polyformaldehyde it is a kind of dystectic , high crystallinity thermoplastic engineering plastic material,  Very good mechanical properties and rigidity, and close to the metal material. It's an ideal replacement material of copper, cast zinc, steel, aluminum and other metal materials POM homo polymer is a semi-crystalline polymer (75–85% crystalline) with a melting point of 175 °C (347 °F). The POM copolymer has a slightly lower melting point of 162–173 °CThe material is widely used in the automotive and consumer electronics industry.Product Features- Good dielectric properties, solvent resistance, non-stress cracking, no porosity- High mechanical strength and stiffness.- Very close to the metal material- High hardness and excellent fatigue resistance.- Good chemical inertness. - Low water absorption Technical DataPROPERTIESTest MethodUnitValueI.Physical PropertiesDensityISO 1183g/cm31.45Water absorption 24hrsISO 62%< 0.3II.Thermal PropertiesHeat deflection temperature - HDT/AISO 75AºC110Min. service temperatureºC-40Max. service temperatureºC100Thermal conductivity at 23 ºCDIN 11359W/(K*m)0.31Coefficient of linear thermal expansionISO 1135910-4*K-11.2Flammability Rating(6mm thickness)UL 94-HBIII.Mechanical Properties at 23ºCTensile strength at yieldISO 527-2MPa63Tensile strength at breakISO 527-2Mpa-Elongation at breakISO 527-2%31Modulus of elasticity after tensile testISO 527-2MPa2,700Modulus of elasticity after flexural testISO 178MPa-Hardness - Shore DDIN 5350583Charpy impact strengthISO 179kJ/m2N.
