Characteristics of LCP
- l 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 ge achieved the thinner
the product.
- Because of its microcrystalline structure, LCP
possesses superior deflection temperature under
load(180-26 0°), continuous usage temperature(200-24
00°C), and solder heat resistance(2600°C
for over 10 s, 310 0°C for 10 s), despite its
relatively low melting point.
