Description
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& acute;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.
