The characteristics of LCP material, what kind of material is LCPA

1. Characteristics. A. LCP has self-reinforcing: it has the characteristics of unconventional fibrous structure, so the unreinforced liquid crystal plastic can reach or even exceed the level of mechanical strength and modulus of ordinary engineering plastics reinforced with dozens of percent glass fiber.

If it is reinforced with glass fiber, carbon fiber, etc., it is far more than other engineering plastics.

b. Liquid crystal polymer also has excellent thermal stability, heat resistance and chemical resistance, and the creep characteristics of most plastics are negligible, and the wear resistance and wear reduction are excellent.

c. LCP has good weather resistance and radiation resistance, excellent flame retardancy, and can extinguish the flame without continuing to burn. Its combustion level reaches the level of UL94V-0.

d. LCP has excellent electrical insulation properties. Its dielectric strength is higher than that of general engineering plastics, and it has good arc resistance. At a continuous service temperature of 200-300 °C, its electrical properties are not affected. The intermittent use temperature can reach about 316.

E. LCP has outstanding corrosion resistance, LCP products will not be eroded in the presence of 90% acid and 50% alkali, and will not be dissolved after contact with industrial solvents, fuel oil, detergents and hot water, nor will it cause stress cracking.

The molding temperature of LCP is high, and the melting temperature is in the range of 300-425 due to its different varieties. LCP melt has low compaction and good fluidity, which is similar to olefin plastics. LCP has a very small coefficient of linear expansion and good dimensional stability.

Summary. LCP is the abbreviation of Liquid Crystal Polymer in English, which is called liquid crystal polymer in China, which is a new type of polymer material, which generally becomes the form of liquid crystal in a certain heating state, so it is named. LCP liquid crystal polymeric resins are not only able to withstand high temperatures, but also have a full range of properties that increase molding productivity.

Replacing ceramic, thermoset, PPS plastic, or other types of LCP plastics can help develop new markets by reducing part size, improving performance, speeding up production, reducing system costs, and helping to develop new markets.

LCP is a special engineering plastic raw material, which has excellent heat resistance and molding processing performance, and generally presents liquid crystals in the molten state, and the polymerization method is mainly melt polycondensation. With the characteristics of unconventional fibrous structure, the liquid crystal plastic without reinforcement can reach or even exceed the level of mechanical strength and modulus of ordinary engineering plastics.

LCP can be used in sporting goods, brake pads, films, flexible printed lines, microwave oven containers, satellite electronic components, jet engine parts, sub-electrical and automotive mechanical parts, etc.

LCP plastic raw material (liquid crystal polymer) is also known as liquid crystal polymer. It is a new type of polymer material, which generally exhibits liquid crystals in the molten state. Main Applications:

1) LCP plastic raw materials have high strength, high rigidity, high temperature resistance, electrical insulation, etc., and are used in electronics, electrical, optical fibers, automobiles and aerospace fields. 2) The fibers made of liquid crystal can be used as fishing nets, bulletproof clothing, sporting goods, brake pads, optical fiber display materials, etc., and can also be made into films, which can be used for flexible printing lines, food packaging, etc. 3) LCP plastic raw materials have been used in microwave oven containers, which can withstand high and low temperatures.

LCP can also be used for printed circuit boards, artificial satellite electronic components, and jet engine parts; for electrical and electronic and automotive mechanical parts or components; It can also be used for medical purposes. 4) LCP plastic raw materials can be added with high filler as integrated circuit packaging material to replace epoxy resin as the packaging material of coil skeleton; used as optical fiber cable gland sheath and high-strength components; Replace ceramics as filling materials in chemical separation towers, etc. 5) LCP plastic raw materials can also be blended with polysulfone, PBT, polyamide and other plastics to make alloys, after the parts are formed, their mechanical strength is high, used to replace glass fiber reinforced polysulfone and other plastics, which can not only improve the mechanical strength performance, but also improve the use strength and chemical stability.

We are currently working on the use of LCP in exterior panels for spacecraft and braking systems for automotive exteriors.

Hello. According to the description of your question, the answer is as follows: LCP board refers to liquid crystal polymer board, which has high strength, high temperature performance and excellent chemical resistance to rubber energy, so it is difficult to find a material that is exactly similar to other materials.

However, if you want to have some specific properties, you can compare it to some materials. For example, in terms of high-temperature performance, LCP plates can be compared to polyimide plates; In terms of mechanical properties, LCP panels are similar to glass fiber reinforced plastic (GFRP) panels. In terms of chemical resistance, LCP boards are similar to fluoroplastics. It is important to note that these analogies are only for specific properties and do not imply that LCP boards and these materials are in all respects identical in aluminous performance.

Industrial liquid crystal polymer (LCP) was originally a solubilized polyphenylene terephthalamide (Kevlar) developed by DUPONT in the United States. Since this type of polymer can only be processed in solution, it cannot be melted, and can only be used as fibers and coatings, which is a special engineering plastic raw material.

Electrical and electronics are the main market for LCP: surface assembly welding technology for electrical and electronics places high demands on the dimensional stability and heat resistance of the material (able to withstand vapor phase welding and infrared welding used in surface assembly technology). Printed circuit boards, artificial satellite electronic components, jet engine parts, automotive mechanical parts, medical aspects.

As an integrated circuit packaging material, instead of epoxy resin as a coil skeleton packaging material; used as optical fiber cable gland sheath and high-strength components; Instead of ceramics as a filling material in chemical separation towers. Instead of plastics such as glass-fiber-reinforced polysulfone (exterior panels in spacecraft and braking systems in automotive exteriors).
