is what black POM engineering plastics ratio natural color need 贵呢?
is what black POM engineering plastics ratio natural color need 贵呢?
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
slow slow very more industry market, due to company good, Company Culture 突出, 吸引 不 less industry light, more add engineering plastics 厂家之路!
engineering plastics has separation very multiple type, separation color, engineering plastics
in color: natural color, black, color . standards grade basic is natural color, grade is black, that color different property can is different, property can different in price upper 面也会 has different.
very more in 购买 时候经常会问 issues is:
engineering plastics ratio natural color need 贵呢?
is add masterbatch, that in market 里便宜 black
[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
