BASF POM is which factors let it high speed development
BASF POM is which factors let it high speed development
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
社会 development, demand improve/increase. very more production 厂家, for/regarding machine 械 元部 parts requirements 也越 越 high, high property can machine parts, reduce loss consumption rate, reduce cost, and also can improve/increase production product quality and output/production volume. this BASF POM进入 我们 视线. lower small large introduction lower POM in market high speed causes has which.
factors: this type of BASF POM material, by as is engineering plastics, is types high processing R&D new product, can substitute/replace very more metal products, made as formed machine important parts, and ratio metal has more more advantages, ratio hard degree good, 就像钢材一样, flexibility degree high, wear resistant loss degree ratio metal need good. therefore formed is very more machine important parts, in automotive 业, electronics electrical, medical devices, sports equipment and other 方面都 has performance.
第二 factors: 国民经济 迅猛 development, BASF POM large market, is engineering large plastics POM也 in this machine, development 起.
第三 factors, application scope expand large, demand increase large. POM初进入 market 时候就 is automotive, machine upper 面 基础零部 parts, in development to 灌溉, medical devices and other 方方面面. field/area wide, upper is will market demand add large. has demand has to, therefore POM market 一直都 is 供不应求 状态.
第四 factors:POM manufacturing 厂家越 越 more, is Raw Materials 廉价, and market demand day increase, 吸引 众 more POM厂家 参 and, various type product launch, make profit more add thick.
[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
