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 is polyoxymethylene (POM) shrink 写, is types commonly used plastics material. this type of material chemical property separation stability, can resistant acid, resistant alkali, is in strong/high acid conditions lower can can make this type of material property, therefore in use need strong/high acid ring 境. this type of material can resistant high temperature, in high temperature lower chemical property 质不会发生改变, therefore can maintain very good outer 形. therefore, this type of material made as product can 够适应 multiple ring 境. positive is due to POM材 material 广泛运 use, currently very more 厂家都 in production POM, Toray POM就 is very 受欢迎 production POM 厂家, that is what Toray POM this 么受欢迎呢?
from use conditions upper 看, Toray POM and other production POM没 has what very large difference, this type of material can in multiple conditions lower use, make is in high temperature conditions lower can, is can long in outer use, is this type of material method UV resistant, outer long 期照射会 make POM chemical property 质发生变化. is POM材 material manufacturing 厂起步 comparison 晚, Toray POM production this type of material already very more year, Model/Grade very more, therefore selection Toray POM, 就意味 has more more selection, can to combined product.
from product price 看, Toray POM也 is comparison combined 算. is POM厂家并不 is very more, therefore in use to this type of material 时, large separation lower large also is selection Imported. remove Japan company Toray POM property ratio high, therefore from price 方面 考虑, selection Toray POM也 is upper upper already 选.
[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
