Pyromellitic dianhydride 99.5%
1.Polyimide
The downstream of phthalic anhydride 99.5% is mainly in the polyimide film industry. Polyimide film is a high-end insulation material with high temperature resistance, widely used in the aerospace and electronics industries.
2.Used as a polymer additive
For example, phthalic anhydride 99.5% can be used as a repair agent and a chain extender to form polyethylene terephthalate (PET) chain extensions. It can also be used as a capping agent for the development of silicone alkyl hybrid materials.
Pyromellitic dianhydride crude
Pyromellitic dianhydride crude is mainly used to produce extinction curing agent B68, and can be used as an additive in polymers for modification.
