There is little entwining of molecules, and application of a slight shearing force orients them in one direction. Liquid crystal polymer's name comes from the fact that it exhibits crystalline properties as a liquid. Once cooled and solidified, it retains a stable state. |
| • |
Molecular chains align themselves when molded, and this generates a self-reinforcing effect, thereby resulting in extremely high strength and elastic modulus. |
| • |
Despite having a high elastic modulus, very much superior vibration absorbing characteristics are exhibited. |
| • |
Linear expansion coefficient in the flow direction in particular is very small, exhibiting a value an order of magnitude less than conventional plastics and on a par with steel. |
| • |
The thinner the product, the higher the proportion of the oriented surface layer, so greater strength and elastic modulus can be achieved the thinner the product. |
| • |
Because of its microcrystalline structure, LCP possesses superior deflection temperature under load (180-260°C), continuous usage temperature (200-240°C), and solder heat resistance (260°C for over 10 s, 310°C for 10 s), despite its relatively low melting point.
