LCP plastic raw material (Liquid Crystal Polymer, liquid crystal polymer) is a new polymer material that exhibits liquid crystallinity in the molten state. It is divided into two categories: thermotropic (liquid crystalline state caused by temperature change) and lyotropic (liquid crystalline state formed by the action of solvent). The material has high strength, high rigidity, high temperature resistance (300-425℃), low linear expansion coefficient, UL94V-0 level flame retardancy and excellent dimensional stability. The density is 1.35-1.45g/cm³, and high mechanical properties can be achieved without fiber reinforcement.
LCP is produced through melt polycondensation process, and solid-phase polycondensation is commonly used to increase the molecular weight of fully aromatic structures. It has low melt viscosity and good fluidity, and is suitable for injection molding (temperature range 300-425°C). It can quickly manufacture thin-walled complex parts with a molding cycle of only 10-30 seconds.
Mainly used in electronics and electrical (printed circuit boards, AI server high-speed connectors [1], connectors), automobiles (fuel parts, braking systems), aerospace (engine parts, external panels) and medical equipment, replacing metals and ceramics in high-temperature and chemical-resistant scenarios. Blending with polysulfone, PBT and other materials can enhance performance and is widely used in precision products such as microwave oven containers and optical fiber connectors.

Main purpose
1. LCP plastic raw materials have high strength, high rigidity, high temperature resistance, and excellent electrical insulation properties. They are used in electronics, electrical, optical fibers, automobiles, aerospace and other fields.
2. Fibers made of liquid crystal can be used to make fishing nets, bulletproof clothing, sporting goods, brake pads, optical fiber and display materials, etc. They can also be made into films for soft printed circuits, food packaging, etc.
3.LCP plastic raw materials have been used in microwave oven containers and can withstand high and low temperatures. LCP can also be used to make printed circuit boards, satellite electronic components, and jet engine parts; it can be used in electronic, electrical, and automotive mechanical parts or components; it can also be used in medical applications.
4. High fillers can be added to LCP plastic raw materials as integrated circuit packaging materials to replace epoxy resin as packaging materials for coil skeletons; as optical fiber cable joint sheaths and high-strength components; as filling materials in chemical separation towers instead of ceramics.
5. LCP plastic raw materials can also be blended with polysulfone, PBT, polyamide and other plastics to form alloys. After the parts are formed, they have high mechanical strength and can be used to replace glass fiber reinforced polysulfone and other plastics. It can not only improve the mechanical strength performance, but also improve the use strength and chemical stability. Research is underway on using LCP for panels on the exterior of spacecrafts and braking systems on automobile exteriors.
