Pyromellitic Dianhydride (PMDA) Manufacturers and Suppliers
Pyromellitic Dianhydride (PMDA), with the chemical formula C₁₀H₂O₆ and CAS number 89-32-7, is a critical organic compound widely used as a monomer in the production of high-performance. In the fine chemicals, specialty polymers and advanced materials field, PMDA serves as a key monomer for polyimides, a curing agent for epoxy resins, cross‑linking agent for polyester resins, and precursor to dyes and other performance‑materials.
Given its high value and application in high‑performance materials (like aerospace grade films, microelectronics, coatings), selecting trustworthy suppliers is imperative.
Why choosing a reliable Pyromellitic Dianhydride (PMDA) supplier matters
When dealing with PMDA, the stakes are high:
Purity matters: Many applications demand ≥ 99 % purity, low moisture and low ash content.
Consistent supply: Delays or quality issues can derail production of high‑value end products.
Regulatory & safety compliance: PMDA is moisture sensitive, may pose occupational hazards (e.g., associated with occupational asthma).
Technical support & handling: Suppliers that can support packaging, storage, shipping (e.g., dry, sealed, inert) reduce risk.

Market trends for PMDA in 2025 and beyond
Demand for high‑performance polymers (e.g., polyimides for aerospace, electronics) is rising, boosting PMDA consumption.
Chinese market is increasingly dominant in supply of fine chemicals like PMDA; many listings highlight “factory direct supply” and strong export capacity.
Purity demand keeps increasing, for example ≥ 99.5%, driven by microelectronics and advanced coatings.
Prices may fluctuate with raw material (tetramethylbenzene oxidation) feedstock costs, energy cost and export tariffs/logistics.
Regulatory and environmental pressures in manufacturing regions may impact production output and thus supply chain reliability.
Typical applications of Pyromellitic Dianhydride (PMDA) and why it’s in demand
Here are key application areas:
Polyimide monomers and films: PMDA combines with aromatic diamines to form polyimides which offer ultra‑high heat resistance, chemical stability, dimensional stability.
Curing agent for epoxy resins: PMDA can act as hardener or cross‑linker, improving mechanical/thermal performance of epoxies.
Cross‑linking agent for polyester resins: Enabling enhanced resin networks for coatings, adhesives.
Dyes & pigment intermediates: PMDA is used in manufacture of phthalocyanine blue pigment and other high‑value derivatives.
Given these uses, the demand for high‑quality PMDA (optimum purity & reliable supply) is not just quantity but performance‑driven.
Frequently Asked Questions (FAQs)
What purity grade should I ask for when buying PMDA?
For high‑end applications (polyimides, electronics), ask for ≥99 % purity. Use the COA to verify.
How should PMDA be stored and handled?
Store in a cool, dry place, sealed to avoid moisture (anhydrides will hydrolyze). Use PPE, good ventilation, and avoid exposure to air moisture. Ensure containers are clearly labelled.
Can PMDA be shipped internationally by air or sea?
Yes, but you must check regulatory classification (chemical safety, export controls, packaging standards). Many suppliers offer fiber drums for sea freight; air freight may require special handling.
What should I look out for when comparing supplier quotes for PMDA?
Compare not just price, but purity, lead‑time, packaging, shipping terms, MOQ, after‑sales support, and reputation. A very low price may hide lower quality or less reliable supply.
