PROBLEM TO BE SOLVED: To obtain sufficient mechanical characteristics and electrical characteristics in polymer products such as high voltage instruments and the like without reducing workability and contribute to preserve the global environment with good biodegradability. SOLUTION: An insulative high polymer material composition is prepared by adding an organic peroxide such as dicumyl peroxide or the like (e.g., adding in the range of 0.2-10.0 phr) as a cross-linking agent to a high polymer material comprising a polylactic acid (e.g., a polylactic acid in which 50-100% lactic acid is used as a monomer) as a main component and mixing and kneading the mixture depending on the added amount of the peroxide and heat treating the mixed and kneaded product to three dimensionally cross-link through peroxide vulcanization. The insulative high polymer material composition is applied to high polymer products such as the high voltage instruments and the like. COPYRIGHT: (C)2008,JPO&INPIT
