Methyl Tetrahydrophthalic Anhydride CAS 19438-64-3
Sinochem is a major Methyl tetrahydrophthalic anhydride supplier. Meanwhile, our firm staffs a group of experts devoted to your development of China Methyl tetrahydrophthalic anhydride.
MTHPA plays a key role in various industries like electronics, medicine, pesticides, resins, and defense. It has a low melting point, low toxicity, and doesn’t evaporate easily, making it easy to work with.
- High temperature stability: The heat deformation temperature (HDT) after curing can reach 120–150°C, which is suitable for high temperature environment applications (such as electronic packaging).
- High dielectric properties: Widely used in the field of electronic appliances (such as PCB insulation materials, transformer packaging).
- Chemical corrosion resistance: Acid, alkali and organic solvent resistant, suitable for anti-corrosion coatings of chemical equipment or tank linings.
- Optical isomer selection
