Item No : Liquid Crystal polymer LCP
Product Name : Liquid Crystal polymer LCP
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¢X), continuous usage temperature(200-24 00¢XC), and solder heat resistance(2600¢XC for over 10 s, 310 0¢XC for 10 s), despite its relatively low melting point.
