LCP liquid crystal polymer (LCP) | technology 文章 | Daoqin plastics raw materials
本文 will detailed introductionliquid crystal polymer (LCP) （LCP）material property can features, application areas and processing process, is material selection and product design provide 参考.
detailed introduction
for/regarding new type plastics understanding, 我们会首先就想 to LCP plastics, this type of plastics full 名Themotropic Liquid Crystal Polyeste, this is types breakthrough plastics made as new type 塑材, it has very high property can separation and especially structure formed.
for/regarding this type of new type manufacturing is made as in types breakthrough, it industrial manufacturing process/workflow for/regarding other made as is different, simple is has mono 体 乙酰化反映同 polycondensation 反映构 formed 工序. this type of is in 乙酰化 process in and polycondensation process in formed process. LCP plastics features is and other process has very large different. this type of in melt lower, separation between is non less. it crystallization material property in liquid 态状态 lower 显现. from 而, it by liquid polymer/macromolecule. material from liquid toward solid 体形态转化之 rear, very stability maintain it solid 态效果.
LCP plastics use scope/range is non 常广泛, this type of liquid formed fiber 塑材经常 by use 做渔网, anti elastic clothing/apparel, type use product, more important is can formed food packaging, made formed film type 塑材也 by use 做 一 soft 质 线路. in large upper, this type of also by use micro container. medical more is has very more use, manufacturing 一 不 can 代替 封装材 material.
this type of material melt temperature degree large in 300摄氏 degree to 425摄氏 degree between, can is for/regarding temperature degree requirements also is very high. it temperature degree separation is 三 方面 requirements, separation is material temperature degree, mold temperature degree requirements also has is can temperature degree requirements.
[材 material basic parameters ]
| density | 1.40~1.60 g/cm³ |
| melting point | 280~350°C |
| heat deflection temperature (HDT) | 250~350°C |
| tensile strength | 130~200 MPa |
| flexural modulus | 8000~15000 MPa |
| molding shrinkage | 0.1~0.5%（各 toward property ） |
| flame retardant rating | UL 94 V-0 |
| dielectric constant | 2.9~3.5 |
core advantages
- high heat resistant property: heat deflection temperature (HDT) can 达250-350°C, can 承受SMT回流焊
- excellent flow property: melt viscosity low, can molding thin 壁面（0.1mm below/following ）
- high dimensions degree: molding shrinkage low, combined precision micro type parts
- solid has flame retardant property: flame retardant can UL 94 V-0
- excellent electrical properties: low dielectric constant and loss consumption 因子, suitable for high frequency 通信
- color chemical resistance: resistant large more has machine solvent agent and chemical product
application areas
micro type connectors, SMT元 parts, ring framework, electrical appliances
天线组 parts, high frequency connectors, frequency parts
传感 device housing/shell 体, system, 燃油喷射 device parts
手术 device 械, pallet, equipment
light connectors, light device parts
injection molding processing process
- drying 处理: 150°C drying 4-8 small 时, moisture content ≤0.02%
- material temperature degree: 300~380°C（ according to grade selection ）
- mold temperature degree: 80~150°C
- injection pressure: 80~150 MPa
- injection speed degree: fast speed （ utilizing LCP excellent flow property ）
- precautions: LCP tool has obvious toward property, products design and gate 位置需 especially attention/notes
