The methyl tetrahydrophthalic anhydride is used as the curing agent of epoxy resin, the solvent-free paint, the laminated board, the adhesive, etc. It has excellent properties of long-term coexistence at room temperature, low freezing point, low toxicity, and so on, which is widely used in electronic and electrical industries.

For example: dry type transformer, insulator, insulating basin, insulating sleeve, insulating paint, high voltage switch, mutual inductor, line output transformer, electric power as well as household capacitor, oil pipeline, etc.

In addition to the above application fields, the methyl tetrahydrophthalic anhydride benefits are particularly suitable for outdoor application.

For example: outdoor transformer, luminous diode, etc.

At present, the manufacturers of methyl tetrahydrophthalic anhydride in China are mainly concentrated in Shanghai, Jiaxing, Wuxi, Nantong and other places, with an annual production capacity of about 50,000 tons actually.

In recent years, due to the rapid development of the automatic forming technology of epoxy insulating products, the new insulation materials that used methyl tetrahydrophthalic anhydride as raw materials have replaced traditional materials such as bakelite, SMC, porcelain and so on. There is a great trend of epoxy insulating materials dominating the world. Meanwhile, its market demand is also increasing.
