Formosa Plastics 钢POM不 can meet/satisfy market demand causes
Formosa Plastics 钢POM不 can meet/satisfy market demand causes
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
market for/regarding high quality POM product demand increase, therefore POM output/production volume requirements 也越 越 high, POM output/production volume 呈现出供不应求 局面, that 么导致POM output/production volume can meet/satisfy market demand causes has which 呢?
causes 一: market upper POM production technology relatively outer has relatively large 差异. tube/pipe demand in add large, is due to development technology relatively outer 晚 许久, therefore in production and output/production volume upper has relatively large 差异. and due to technology water low, product types comparison mono 一. very more demand in selection 时候也会 has very large property.
causes 二: market demand growth fast, POM technology upper demand 步伐, very more 厂家都存 in production small, production technology to and other more issues. enterprise can 够投入 more more 资金进行科研 technology development, made POM development, formed market more balanced.
causes 三, more Formosa Plastics 钢POM this 样 专业 engineering plastics market rear, 凭借 专业 technology water 平, more product market 主导 位. Formosa Plastics 钢POM in market rear, has very more product types demand selection, another formed technology to this type of product upper 添花.
more high industrial in development, for/regarding POM demand in day increase. outer product is more good in market sales, is 不会转 let technology to 厂家, this need enterprise breakthrough heavy heavy difficult, in product technology upper 寻找出路, in ensure profit lower, reduce cost, improves technology, is Domestic POM understanding 救之路.
[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
