POM plastics is types how 样 材质
POM plastics is types how 样 材质
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
POM plastics is types use separation 广泛 材质, in very more industry or is field/area in, its need use to this type of 材质, but also due to this type of features, therefore also can substitute/replace has color metal use, therefore in this type of lower, is machine also is machine 床, is automotive industry or is in industrial industry in, its 实也都 is can use this type of 材质.
meanwhile 我们平时 use to comparison small type use electrical appliances in, its is need use to this type of product, ratio 如说我们常 commonly used electrical 饭煲当 in, its is need use to this type of POM plastics, meanwhile in use water leading or is pipeline in, 也往往 need use to POM plastics, therefore this type of function large is 专业不 can overlook.
meanwhile this type of POM plastics, also has 一 方面 features, that is this type of its for/regarding ring resistant property and resistant has machine solvent agent property is comparison good, but also this type of future can use to more add more 起, this 同样也 is this type of features.
from appearance in, can to this type of its and other plastics 材质看起 is non versus 似, is this type of 材质也 is combined formed resin in types, therefore 说自然也就 tool has combined formed resin other advantages.
meanwhile this type of also has very obvious benefits, that is this type of heat stabilized property its is non good, but also this type of large in use process 当红也 is easy separation understanding.
this type of its use time and scope/range is separation 广泛, therefore large 家应该 more add understanding this type of 材质.
[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
