Describe
LAPEROS® LCP is a leading super engineering plastic that has a thinness and fluidity unheard of in typical engineering plastics. Heat-resistant and possessing an incomparable mechanical strength, LCP has the unique attribute that the thinner the product becomes, the greater its mechanical strength. Moreover, it has a low coefficient of linear thermal expansion close to that of metal. It is often used in superminiature precision connectors for ever-smaller IT devices like tablets and smartphones. It is at the top globally* with a total market share of 37%.
