POM M90 (CAS No.None)
- 物化性质
- 力学性能优良：弹性模量高，摩擦系数低而稳定，耐磨性和自润滑性好，硬度和刚度高，与金属接近；抗张强度和模量接近钢材，耐疲劳性优异，可承受一百万次以上反复负荷，抗蠕变和应力松弛能力强；吸水率小，尺寸稳定性好，力学性能随温度变化小（共聚物略大于均聚物）。热变形温度：均聚约136℃，共聚约110℃；220℃以上易分解释放甲醛，可140℃短期使用，长期使用温度-40~100℃。耐气候性较差，长期紫外光曝晒会老化，表面粉化龟裂，室外应用需加稳定剂。
- 密度
- 约1.41 g/cm³

Product Name:Polyoxymethylene M90
English Name:Polyoxymethylene M90
CAS No.:9002-81-7
Aliases:Polyacetal, Polyformaldehyde, Acetal resin, POM
Molecular Formula:(CH2O)n
Physical Properties:Excellent mechanical properties: high elastic modulus, low and stable friction coefficient, good wear resistance and self-lubrication; high hardness and rigidity close to metal; tensile strength and modulus close to steel; excellent fatigue resistance, can withstand more than one million repeated loads; strong creep and stress relaxation resistance; low water absorption and good dimensional stability; mechanical properties vary little with temperature (copolymer slightly more than homopolymer). Heat distortion temperature is about 136°C for homopolymer and about 110°C for copolymer; decomposes above 220°C releasing formaldehyde; short-term use at 140°C, long-term service temperature -40~100°C. Poor weather resistance: long-term UV exposure causes aging, surface chalking and cracking; stabilizers should be added for outdoor applications.
Uses:Mainly used for manufacturing automotive exterior parts, wheels and gears, and also for precision mechanical parts, bearings, sliders, blades and other wear-resistant parts requiring high rigidity, low friction and dimensional stability.
Technical Specifications:
Density: approx. 1.41 g/cm³
Melt flow rate: approx. 9 g/10min (190°C/2.16kg)
Heat distortion temperature: approx. 110°C (copolymer, 1.82MPa)
Tensile strength: approx. 60 MPa
Long-term service temperature: -40~100°C
