POM plastics in ring 境适应 property 方面 has advantages
POM plastics in ring 境适应 property has advantages
POM polyoxymethylene (POM) | technology 文章 | Daoqin plastics raw materials
本文 will detailed introductionpolyoxymethylene (POM) （POM）material property can features, application areas and processing process, is material selection and product design provide 参考.
detailed introduction
POM plastics has very strong/high ring 境适应 property, its 实我们知道, in this type of plastics in use 时候十 separation 广泛, it use therefore 广泛, very important 方面, positive is is it property comparison strong/high, ratio it in use 时候, can to very good temperature degree property, it can to very high temperature degree lower deformation, meanwhile also can in low temperature property can lower, let 自己达 to very good as property can, positive is is this 一点, therefore in has very more use 户也都 in use this type of property can plastics.
remove it in temperature degree ring 境适应 property comparison strong/high outer, another it in overall chemical ring lower, it still can performance 出自己 advantages, ratio it can in type, alcohol type and other and other chemical ring lower to very good property can performance another in 汽油, lubricated and other and other chemical ring lower for/regarding 自己造 formed effect/influence, therefore it in very more chemical ring complex lower, 往往也都 is selection this type type product, in more more 时候, this type of parts use is 一 根本 property performance.
its in 一 材 material use 时候, 往往会 in strong/high acid ring lower use, this if is other plastics 也就不 can 适应, is if is this type of POM plastics, can more good 适应, positive is is it 本身也就 is for/regarding strong/high acid property chemical reaction has very good performance. but also in industrial lower, oxidation agent ring for/regarding material requirements more add high, is high strong/high oxidation lower let material to oxidation let it lifespan decrease/reduce, is if use is this type of material 话, also can to very strong/high property
[材 material basic parameters ]
| density | 1.41 g/cm³ |
| melting point | 165~175°C |
| heat deflection temperature (HDT) | 110~124°C |
| tensile strength | 60~70 MPa |
| flexural modulus | 2600~3100 MPa |
| notched impact strength | 70~100 J/m |
| molding shrinkage | 1.8~2.5% |
| friction coefficient | 0.1~0.3 |
core advantages
- excellent machine strong/high degree: tensile strength 60-70MPa, is thermoplastic property plastics in force property can most excellent material 之一
- color wear resistance and lubricated property: friction coefficient low 至0.1-0.3, is manufacturing gears and bearings 理想材 material
- high rigidity: flexural modulus can 达2600-3100MPa, dimensional stability good
- excellent fatigue resistance: in 反复应 force function lower still can maintain good force property can
- good chemical resistance: for has machine solvent agent, type, material has excellent 良 抵 resistant can force
- excellent dimensional stability: water absorption low, in wet ring in property can small
application areas
gears, strip/profile, 凸轮, bearings, sleeve/set, strip/profile
门锁, rise drop device, safety belt/tape 扣, 燃油泵组 parts
开关, electrical appliances, connectors, 卡扣, 键盘按键
拉链, machine, frame, toys parts
阀门, water leading, 淋浴喷头, pipeline parts
injection molding processing process
- drying 处理: POM water absorption relatively low, generally 80°C drying 3-4 small can
- material temperature degree: 180~220°C（ homopolymer POM偏 high, copolymer POM偏 low ）
- mold temperature degree: 60~120°C（ high mold temperature can obtain more good crystallization degree and surface quality ）
- injection pressure: 70~120 MPa
- injection speed degree: in and other to fast speed
- precautions: POM heat stabilized property 差, material temperature degree ultra- 240°C, machine front must use PE清洗
