SUMIKASUPER LCP is a thermotropic liquid crystalline polyester that possesses the highest heat resistance among all engineering plastics. Its basic chemical composition is shown in the diagram below. Thermotropic liquid crystalline polyester is one カジノ シークレット 登録 the most common types カジノ シークレット 登録 liquid crystalline polyester (LCP).

As indicated by their name, one property カジノ シークレット 登録 liquid crystalline polyester is that they become liquid crystalline state when they enter a molten state. This special phenomenon, unique to liquid crystalline polyester, can be observed under a polarizing microscope: as the temperature カジノ シークレット 登録 a polymer increases and it begins to melt, its light transmittance also increases significantly.

With SUMIKASUPER LCP, the liquid crystalline state (crystalline state) is indicated for the liquid crystallization temperature or higher. Liquid crystal molecules become oriented via injection molding, and it shows characteristics such as high strength, high the elastic modulus, high flow characteristics, and a low coefficient カジノ シークレット 登録 linear thermal expansion.
