PPS plastics is types use separation 广泛 材质
PPS plastics is types use separation 广泛 材质
PPS polyphenylene sulfide (PPS) | technology 文章 | Daoqin plastics raw materials
本文 will detailed introductionpolyphenylene sulfide (PPS) （PPS）material property can features, application areas and processing process, is material selection and product design provide 参考.
detailed introduction
in market upper its 实出现 very more different plastics 材质, its in very more plastics is large comparison less to, ratio 如说PPS plastics is types types, in use upper comparison 广泛 一 types 材质, but also this type of in use process in, also is can 发挥出 non large advantages.
therefore in very more industrial and production industry parts 方面, is can use this type of 材质, but also this type of 材质本身 features 也决定 it applications, ratio 如说PPS plastics this type of its in has non large advantages, that is this type of resistant thermal properties 确实也 is very 不错, but also in chemical stability property can 方面也不错, therefore 就不会发生 property can and other issues, this type of product electrical insulation property can 方面, its is very 不错, therefore large in use this type of 材质以 rear, use 担心会 has conductive issues, in very more electrical appliances and home appliances industry in, its is can use to this type of 材质.
当然 this type of also has 一 方面 advantages, that is wear resistance can is non 常不错, therefore in gears or is bearings 方面, a large amount of using/adopting PPS plastics this type of 材质, this type of also already made as 一 变 pressure device external structure 方面, but also for/regarding very more comparison precision parts production, is can to non 常不错 效果.
versus large for/regarding PPS plastics this type of more add understanding and 清楚以 rear, large 家也一定会 more add use good this type of 材质, has this 样 话, can will this type of 材质发挥出一 巨 large 效果.
[材 material basic parameters ]
| density | 1.34~1.42 g/cm³ |
| melting point | 280~290°C |
| heat deflection temperature (HDT) | 260°C（ reinforcement rear ） |
| tensile strength | 65~90 MPa |
| flexural modulus | 3800~4500 MPa |
| 连续 use temperature degree | 200~240°C |
| flame retardant rating | UL 94 V-0 |
| water absorption | 0.02~0.05% |
core advantages
- 卓越 high temperature resistance property can: use temperature degree can 达200-240°C, short can resistant 260°C
- excellent chemical resistance: 几乎不受任何 chemical product 腐蚀, resistant acid alkali property strong/high
- solid has flame retardant property: 无需添 add flame retardant can to UL 94 V-0 grade
- low water absorption: dimensional stability in wet ring in 几乎不受 effect/influence
- excellent electrical properties: high temperature high frequency lower still maintain good insulation property can
- good dimensional stability: molding shrinkage small, combined precision parts manufacturing
application areas
SMT connectors, electrical appliances, 开关, electrical container outer housing/shell, IC封装
发动 machine parts, cooling system, increase pressure device parts, device
泵叶轮, 阀门, seals, bearings, device
machine internal structural parts, machine parts
micro parts, machine parts, viscous coating
injection molding processing process
- drying 处理: 150°C drying 4-6 small 时, moisture content ≤0.05%
- material temperature degree: 300~340°C
- mold temperature degree: 130~150°C（ high mold temperature has crystallization ）
- injection pressure: 70~130 MPa
- injection speed degree: in speed to fast speed
- precautions: PPS melt viscosity low, anti material and 流涎
