High tracking resistance thermosetting resin (diallyl resin)
Osaka Soda produces diallyl phthalate resins "Daisodap" and "Daiso Isodap" at its Matsuyama factory. These resins excel in insulation and dimensional stability under high temperature and high humidity environments, while also demonstrating excellent tracking resistance. Even in unfilled molded products that do not contain fillers or additives, the comparative tracking index (CTI) exceeds 600V. The non-phthalate allyl resin "RADPAR AD-032" also possesses very good tracking resistance, similar to Daisodap. These resins are characterized by minimal discoloration during curing and the ability to be colored in bright hues. Their use is also expected in applications such as electric vehicle components, where high voltage resistance is required.
