  Liquid crystal polymer (LCP)
It is a new type of high-performance special An engineering plastic
Overview LCP is a new type of polymer with outstanding properties
LCP is a wide range of materials: A
lyotropic liquid crystal: it needs to be processed in solution; b
Thermotropic liquid crystal: it can be processed in molten state
The first industrialized liquid crystal polymer was lyotropic poly-p-phenylene-p-phenylenedicarbonamide (Kevlar & amp; reg;) developed by DuPont company in the United States Because this type of polymer can only be processed in solution and cannot be melted, it can only be used as fiber and coating
The following only includes thermotropic LCP
Appearance of LCP: Beige (there are also white opaque solid powder); LCP density: 1
35-1
45g/cm & amp; sup3；。
Thermotropic LCP has the structure of all aromatic polyester and copolyester
It also has a dense linear polymer chain structure, and the formed products have good Good unidirectional mechanical properties
Good high temperature performance (thermal deformation temperature 121 ~ 355 ℃), good radiation resistance, hydrolysis resistance and Weather resistance, chemical resistance, inherent flame retardancy, low smoke, high dimensional stability, low moisture absorption, very low coefficient of linear expansion, high impact Impact strength and rigidity (compared with the same weight, the strength of LCP is greater than that of steel, but the rigidity is only 15% of that of steel)
LCP is resistant to acids, solvents and hydrocarbons And other chemicals, and has good barrier property
Liquid crystalline aromatic polyester in liquid crystalline state, because its macromolecular chain is oriented, it has abnormally regular fibrous structure, special properties and strong products The degree is very high, no less than metal and ceramics
A variety of thermoplastics with tensile strength and flexural modulus that can be developed in more than 10 years
Adopted single The properties, processability and price of liquid crystalline polyester are also different with different body
Different fillers and filler addition also affect Its performance
