Because it has excellent thermal and electrical properties and is easy to process using extrusion, injection, and other molding methods, it has been widely used as a molding material for industrial and consumer products.
It has been found that when immersed in or in contact with certain environmental substances, such as animals and plants, mineral oils and fats, plasticizers, organic solvents, etc. under stress, cracks occur, which then grow and lead to destruction. It was done.

Also included are mixtures containing fillers such as pigments. Furthermore, the characteristics are improved by the present invention because, by adding ultrafine inorganic compounds, these fine particles form nuclei for crystal formation and control the development of crystal structure, thus providing excellent environmental resistance (resistance to materials). It is considered to indicate cracking property). The amount added is limited from the viewpoint of the effect on the environmental resistance (crack resistance) of the composition, and the effect is difficult to notice if it is less than 0.05 part by weight.
