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
PPS plastics 同样也 is engineering plastics types, is it comprehensive property can especially excellent. 我们先 说说 it 起源吧, 他并不 is 我们研 made, it USA, is USA Phillips company in 1971 year R&D, rear has good more 都进行 R&D, 当然我们也曾经进行 a small amount of research, is has can 够持续 production.
although is production 商, it is distributor, in industrial very more 方面, has use PPS made formed product, due to it 出现, let industrial production has very large 进步, that 么PPS to has what excellent features, to this more 人 青睐呢, 笔者告诉你, this type of PPS plastics, has very good high temperature resistance features, meanwhile has very strong/high corrosion resistant property, more good is has high frequency insulation property and excellent flame retardant property, due to PPS plastics tool has this good features, it let in use more safety, 谁不希望自己 use product safety 呢, positive due to 如此, in market upper can has 一席之.
in, due to PPS color performance, has more more industry in, use PPS plastics as is can less Raw Materials, therefore, make PPS Raw Materials sales 越 越 good, PPS plastics sales outlook/prospects is light 芒.
我们 看一看PPS plastics color 之处, in automotive industry upper, PPS plastics has very large specific gravity, tube/pipe is device, add hot device, also is base/seat, bearings, 都离不开PPS plastics 影子, in machine industrial 方面, 阀门, bearings, active 塞样样都离不开PPS plastics, in electronics electrical appliances, textile fiber and other and other 方面, can
[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
