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 LCP plastics generate process, is 人们不断 research and 实验 结果, therefore formed high type, high property can plastics, from make 我们 生 active more add 方面.
for/regarding LCP plastics 说, is fiber structure, therefore for/regarding is simple 处理LCP plastics, its strong/high degree can ultra- other processing plastics product good 几倍, therefore for/regarding LCP plastics 说, 就会经常 by used for that high pressure ring lower.
当然 for/regarding LCP plastics, is has non good stability property, and let 人不敢 versus is, LCP plastics in 燃烧 情况 lower, can retardant its 继续燃烧, therefore for/regarding 经常出现火灾但 also must use plastics 方, 我们就 can selection use LCP plastics.
我们 generally use plastics 捅装一 acid property or alkali property liquid 体, is if selection property can plastics 捅, 我们就会发现 time 久, that plastics 桶就会 deformation, is if this 时候, selection 由LCP plastics formed plastics 桶, 我们就 can long time that or acid or alkali liquid 体.
for/regarding LCP plastics also has more add has use function, that is electrical 悍, can in this 里发挥 function main/primary causes is, LCP plastics heat resistant property and stability property.
for/regarding 我国突飞猛进 科技 development, LCP plastics 也做出 一部 separation 贡献, relatively large application is, in 人造文星 electronics parts, small application is in 我们厨房里 micro 波炉, also by used for is 我们治疗疾病 medical in, therefore this from upper LCP plastics function positive in by 广泛 挖掘, slow slow is more more 人服务.
[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
