construction industry and furniture ring 境必备 PPS plastics
construction industry and furniture ring 境必备 PPS plastics
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
for/regarding 我们 接触 plastics 说, large separation is outer 国人研 made, is has non technology, is for/regarding used for this plastics, also is non in 行, good ratio USA PPS plastics, by very good application in construction and upper.
我们 in 建房子 时候, 一定会 need plastics, ratio 如帮我们传送 water tube/pipe 子, and electrical in lower need plastics 保护 情况 lower, therefore requirements water tube/pipe and tube/pipe using/adopting plastics must tool has long time corrosion resistant property, deformation, resistant wet and resistant acid alkali property property 质.
in 开始 时候, 我们 科学家也 is a large amount of 实验, rear 才发现PPS plastics full can meet/satisfy upper high requirements, therefore slow slow PPS plastics, formed is construction industry plastics product, and for/regarding using/adopting PPS plastics 家庭 说, will in water tube/pipe 会爆裂 or is lower 线断 情况, therefore can more good 享受美 good ring 境.
in 人人都 in 追求健康 environmental protection ring 境, therefore in selection use product 时候, 我们都会 selection that odor, environmental protection, material product, another PPS plastics insulation property non good, therefore 我们家 开关按钮周围 plastics can selection this type of plastics, from 而避免发生触 electrical 情况.
therefore upper, in selection plastics products 时候也会本 this 原则, therefore 我们就 to large recommendation PPS plastics, is 经 专业 科研人员 实验, in use plastics industry 里, PPS plastics 无害, therefore small 编才敢 in 此呼吁 large is safety selection PPS plastics made as use product 吧.
[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
