Delrin homopolymer polyoxymethylene (POM) ratio copolymer polyoxymethylene (POM) advantages
Delrin homopolymer polyoxymethylene (POM) ratio copolymer polyoxymethylene (POM) advantages
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
and copolymer polyoxymethylene (POM) different, DuPont Delrin® is types tough, light resistant use polyoxymethylene (POM) resin, tool has wear resistant, low friction, low 噪音, low moisture absorption property and excellent elastic property and other inner in features. Delrin®广 is 人知, by used as polyoxymethylene (POM) resin industry 术语. is, non has polyoxymethylene (POM) resin tool has property can.
Delrin® how to and different?
Delrin® is types homopolymer polyoxymethylene (POM), it tool has separation structure, ratio copolymer polyoxymethylene (POM) tool has more large crystallization structure, tool has more strong/high separation combined force. therefore, Delrin® is currently can use tool rigid property, strong/high degree relatively high non reinforcement type engineering polymer.
Delrin® and copolymer polyoxymethylene (POM) versus ratio has many significantly advantages
in high property can, high degree machine application areas, use Delrin® can optimization parts design and production:
in obtain and other material parts property can front lower, parts thick more thin
[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
