What is Pyromellitic Dianhydride CAS 89-32-7?
The English name of pyromellitic dianhydride is PyromelliticDianhydride (abbreviated as PMDA, the same below), and it is mainly used for synthesizing polyimide. Due to the excellent chemical properties of polyimide, such as extremely high heat resistance, resistance to acids and alkalis, excellent mechanical properties, electrical properties and dimensional stability, it is widely applied in high-tech fields with strict requirements for material performance, including aviation, aerospace, microelectronics and atomic energy.
Pyromellitic Dianhydride CAS 89-32-7 Use
Diphenylmethanediamine dianhydride is used in the manufacture of polyimide resins, which are employed as raw materials for high-temperature resistant electrical insulating varnishes. It is also used to produce epoxy resin curing agents and plasticizers, urea-formaldehyde resin stabilizers, phthalocyanine blue dyes, corrosion inhibitors, instant adhesives, electronic photography colorants, etc.
Diphenylmethanediamine dianhydride and its derivatives have a wide range of applications. PMDA is mainly used as a curing agent for epoxy resins and a raw material for polyimide, cross-linking polyester resins to produce diphenyl-type polyetherimide resins, which is a high-temperature resistant engineering material that can be used continuously and for a long time at 2600°C.
Diphenylmethanediamine dianhydride is the main raw material for manufacturing polyimide heat-resistant engineering plastics and insulating films; it can be used as a raw material for the synthesis of epoxy resin curing agents, stabilizers, dyes, etc.
Diphenylmethanediamine dianhydride can be used to produce polyimide resins, high-temperature resistant electrical insulating varnishes, PVC plasticizers, synthetic resin cross-linking agents, and epoxy resin curing agents, and is also used to produce phthalocyanine blue dyes, etc.
