PPA plastics is types high temperature resistance 材质
PPA plastics is types high temperature resistance 材质
PPA poly 邻苯二甲酰 amine | technology 文章 | Daoqin plastics raw materials
本文 will detailed introductionpoly 邻苯二甲酰 amine （PPA）material property can features, application areas and processing process, is material selection and product design provide 参考.
detailed introduction
in 我们 生 active in, need use to plastics this type of 材质 方 its is non more, in plastics 材质当 in, 同样也 is can separation is very more types type, is large separation for/regarding specific plastics type type is very understanding, therefore in this type of lower, also is large also is need more add understanding lower this 材质, ratio 如说现 in in very more industry in, its is need use to PPA plastics this type of 材质.
therefore in very more for/regarding this type of also is non material and, therefore this in this type of lower, large also is need this type of material.
PPA plastics this type of material has non large advantages, that is this type of high temperature resistance property can its is non 常不错, therefore in this type of lower, use this type of can resistant degree above high temperature, other plastics high temperature resistance property can its 实就没 has that good, this is this type of plastics in use in advantages.
PPA plastics density is comparison low, is this type of stability property can its is non high, therefore in very more industry in, is can use to this type of 材质, use this type of benefits its is non more, this type of in use process in, generate has has material 质, is types versus environmental protection 材质, this advantages is non obvious, in in very more field/area in, its 实也都 is to this product advantages.
combined utilizing this type of PPA plastics advantages, rear this type of disadvantages, can production more more more add good product, PPA plastics this type of 材质也 can in non more industry and field/area in use, 发挥出十 separation large function.
[材 material basic parameters ]
| density | 1.15~1.25 g/cm³ |
| melting point | 295~315°C |
| heat deflection temperature (HDT) | 280~300°C |
| tensile strength | 80~120 MPa |
| flexural modulus | 3000~10000 MPa |
| 连续 use temperature degree | 150~190°C |
| water absorption | 0.5~1.5% |
| flame retardant rating | UL 94 V-0（部 separation grade ） |
core advantages
- high heat resistant property: melting point can 达295-315°C, heat deflection temperature (HDT) ultra- 280°C
- excellent force property can: tensile strength and rigid property excellent 于普通 nylon
- low water property: versus ratio PA6 and PA66, water absorption large reduce, dimensional stability more good
- good chemical resistance: for large more automotive liquid and chemical product has excellent 良 抵 resistant can force
- good dimensional stability: in temperature wet degree large ring in property can stability
- can resistant SMT回流焊: suitable for surface technology （SMT） process
application areas
SMT connectors, 开关, electrical appliances, LED支架, ring framework
发动 machine parts, cooling system, system, speed parts
泵体, 阀门, bearings maintain 架, gears
sports equipment, power tools housing/shell
injection molding processing process
- drying 处理: 120°C drying 8-12 small 时, moisture content ≤0.1%
- material temperature degree: 300~330°C
- mold temperature degree: 120~160°C
- injection pressure: 80~150 MPa
- injection speed degree: in speed
- precautions: PPA熔 melt temperature degree high, ensure injection molding machine tool 备足够 add hot can force
