Liquid Crystal Polymers (LCP)
Properties and Applications
Liquid crystal polymers (LCPs) are wholly aromatic polymers. They consist of tightly packed, rigid polymer chains which display order in the melt state very similar to nonpolymeric liquid crystals. Most LCP’s have outstanding weathering, heat, chemical and radiation resistance and exhibit outstanding strength even at extreme temperatures.1,2 For example, LCPs resist stress cracking when exposed to aromatic or halogenated hydrocarbons, strong acids, bases, ketones, and most other aggressive chemicals.
The excellent dielectric properties and the ability to withstand (lead-free re-flow) soldering temperatures make liquid crystal polymers an excellent choice for electronic components such as static dissipative connectors, encapsulated capacitors, platable connectors, electrical motor components, and device housings. Their outstanding mechanical properties and excellent chemical and heat resistance make them also well suited for mechanical components that have to withstand high loads, extreme heat and aggressive chemicals. They are often suitable replacements for other engineering materials, including metals and ceramics.3
