PMMA plastics applications and classification
PMMA plastics applications and classification
PMMA亚克 force | technology 文章 | Daoqin plastics raw materials
本文 will detailed introductionpolymethyl methacrylate (PMMA) （PMMA/亚克 force ）material property can features, application areas and processing process, is material selection and product design provide 参考.
detailed introduction
if 我们说PMMA, very more 人都不知道 is what 东西, is if 我们换一 types method versus large for it 就会感 to non 常熟悉, its 实PMMA plastics is has machine 玻璃, it is 我们生 active in can 见 一 types Raw Materials, ratio 如我们 杯子 and 吊灯就 is use this type of has machine made formed, lower 面我们 is large introduction it applications and classification.
PMMA plastics application can is more plastics in and 我们生 active 贴切 一 type, it application is separation 广泛, 我们几乎随时随处都 can to it inner 英, ratio upper 橱窗, electrical 话亭就 is use it made formed, also has 广告牌, 灯箱. 甚至连火车 upper and 我们 化妆 product in has this type of material. in addition it also can made formed 我们漂亮 吊灯 and and other and other.
usually lower according to PMMA plastics appearance, can will has machine separation is type, type is Common, is 普通 无 color transparent 玻璃, it meanwhile is use amount relatively large type. type is in color transparent 玻璃 基础 upper add color, 我们叫 it color sheet/plate, use it can made as industrial product, 灯箱以 and 吊灯.
第三 type is light has machine 玻璃, this type of and PMMA plastics ratio color more add 鲜艳, gloss degree very high, usually will it hot pressure, rear again will surface abrasion 平, this can formed surface has pressure process 玻璃, 我们经常 suitable this type of methods made as 一 动 material type and other 宣传材 material.
rear type is pressure has machine 玻璃, Common is 浴室 门, it features is can light is 却看不清楚形状.
[材 material basic parameters ]
| density | 1.18~1.19 g/cm³ |
| 玻璃化转变 temperature degree | 105°C |
| light transmittance | 92~93% |
| tensile strength | 55~75 MPa |
| flexural modulus | 2700~3200 MPa |
| notched impact strength | 15~25 J/m |
| molding shrinkage | 0.3~0.7% |
| 洛氏 hardness | M70~M90 |
core advantages
- 卓越 optical property can: light transmittance high 达92-93%, is optical property can most good thermoplastic property plastics
- excellent weather resistance: long outer use 不变黄, 不脆化, resistant outer
- good surface hardness: in thermoplastic property plastics in hardness relatively high, resistant scratch property good
- excellent can processing property: can injection molding, extrusion, molding, can hot and bonding
- 丰富 color color selection: can made formed various transparent, semi transparent and transparent color
- good electrical insulation property: suitable for lighting and electronics application
application areas
LED lamp covers, light guide sheet/plate, 灯箱, lamp covers
招牌, 灯箱, show/display 架, POP show/display
隔音屏障, light 顶棚, 浴室隔断, decoration sheet/plate
lamp covers, table/sheet 盘, cationic sheet/plate, 车窗
machine 屏幕保护, LCD light guide sheet/plate, device sheet/plate
injection molding processing process
- drying 处理: 80~90°C drying 4-6 small 时, moisture content ≤0.05%
- material temperature degree: 210~250°C
- mold temperature degree: 40~80°C
- injection pressure: 60~100 MPa
- injection speed degree: slow speed to in speed （避免 bubbles and 银纹）
- precautions: PMMA for force 敏感, molding rear 建议进行退火处理
