POM plastics has which important features ？
POM plastics has which important features?
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
plastics in 我们生 active in can is non 常普遍 industrial product, but also in 几乎任何一 industry is need use to this type of product. therefore 我们现 in for/regarding plastics understanding is comparison in-depth, that 么我们当 in has separation let is POM plastics this type of product, for/regarding this type of product 说, can true positive for its understanding can can is 不会太 more, therefore 我们今天就 understanding it Knowledge.
首先我们想 need for product has in-depth understanding, that 么首先 need 知道 就 is this product important features, is positive is is has this property can, can 够咋诸 more industry also has field/area in to application, therefore 我们也就先 from this 方面开始 understanding.
而我们 POM plastics tool has important features is it stability property is comparison color, is in processing front is can drying 吗, therefore generally is 会进行一定 preheating, that this for/regarding product dimensions issues, can to very large stability function.
its it machine strong/high degree also has rigid property is comparison high, therefore in industrial upper use is non commonly used, but also positive is is this important 方面, in market upper need ratio large more product 专业, therefore is comparison to market 方面欢迎, in other also is need 继续改进.
meanwhile for/regarding POM plastics 说, it fatigue strong/high degree is relatively high, this can is it important features, is it can ratio other product more more advantages important causes, therefore very more ring for/regarding this requirements is comparison high, that selection this type of product is in material in.
[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
