Liquid Crystal Polymer (LCP)
Description (definition)
Liquid Crystal Polymer (LCP) is a high-performance plastic that offers exceptional properties such as high strength, heat resistance and low moisture absorption due to its special molecular structure. LCPs retain their stability even under extreme temperatures and chemical stress and are therefore ideal for applications in electronics, the automotive industry and medical technology. They are also known for their excellent dielectric properties.
Example
One example is the use of LCP in flexible printed circuit boards for electronic devices. Thanks to its heat resistance and excellent insulation, LCP is used in smartphones, wearables and high-frequency antennas.
What properties make LCP special?
LCPs offer an exceptional combination of high tensile strength, low coefficient of thermal expansion and chemical resistance. They are lightweight, retain their shape at high temperatures up to 300 °C and have low moisture absorption, making them ideal for demanding applications.
Where are Liquid Crystal Polymers used?
LCPs are widely used in the electronics industry, for example in connectors, microchips and flexible printed circuit boards. In the automotive industry, they are used for heat-resistant components such as sensor housings. They are also used in medical technology, for example in devices that require sterilization.
How is LCP processed?
LCPs can be formed by injection molding, extrusion and other thermoplastic processing methods. Due to their flowability, they can be processed into thin-walled and complex components, making them ideal for miniature applications.
