Articles composed of organic materials are light, colourful and compact. These features are based on the fact that organic materials have significant potential, such as a lower density than metals or ceramics, and diversity in performance in combinations of weight and strength, in addition to a higher efficiency for a higher production rate based on a shorter injection molding time of plastics into a mold. When the environmental loads of electrical and electronic articles in automobiles made from organic materials are taken into consideration in view of their entire processing and production into articles from the raw materials, transportation, application and consumption, and waste treatment, organic materials have an advantage with respect to other material type. Also, the new trends in “light, thin, short and small design effects” brought about a large selection of plastic materials as a business policy and effective strategy for various advanced designs of articles which resulted in a comfortable life, low energy loss, lower consumption of energy related to thermal energy and the emission of carbon dioxide.
