POM masterbatch can solution plastics water water issues 吗?
POM masterbatch can solution plastics water water issues 吗?
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
in 整理资 material 时候, 我发现 我们之 front has comparison value separation 享 案例. is has hydrophilic 自接触 this 案例, therefore, upper plastics and detailed 讲 整 案例 process
珠三角客户找 to 我们, is is solution product in injection molding to heavy issues. to 我们一 sample, lower 面 图我们看 to, product to issues:
for 此, 我们刘总马 upper 就判断出, product to this issues is due to and color powder / masterbatch versus 容. product is use POM FG2025 natural color 做, 客户考虑 to cost issues, 就随便 use black 母, 自然就会出现 this type of issues.
rear, engineering plastics is recommendation 一款POM专业 black 母, can 想而知, through.
我们刘总 in plastics industry mixed 战10余 year, for 此, also for plastics products in injection molding 时会出现 water 纹 情况, as 出 一 small 贴士, 我整理 一 lower, 也顺便 separation to large 家吧:
1, reduce hot temperature degree
[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
above inner 容由Daoqin plastics raw materials has companytechnology 部整理 editor | 如需 understanding more more POM polyoxymethylene (POM) material 信息, electrical inquiry
