Properties and Usage:

Pyromellitic anhydride is a highly efficient chemical intermediate, mainly used in polyester production, coatings, adhesives, plasticizers and synthetic resins.

Polyester production

PET manufacturing: Pyromellitic anhydride is the core raw material for the synthesis of polyethylene terephthalate (PET), which is widely used in the production of plastic bottles, fibers and films. Whether it is used in beverage bottles, food containers, or home textiles, pyromellitic anhydride provides a guarantee for the high-quality performance of PET.

Coatings industry

Durable coatings: Polyester resins produced by the reaction of pyromellitic anhydride with other chemicals are used in automotive and industrial coatings. These resins have excellent wear and corrosion resistance, which can effectively protect equipment and structures and extend their service life.

Adhesives

Construction and industrial adhesives: Pyromellitic anhydride is an important ingredient in the manufacture of efficient construction adhesives and industrial adhesives. These adhesives ensure a strong bond between building materials and industrial products, improving structural strength and durability.

Plastic plasticizers

Enhanced flexibility: Pyromellitic anhydride plays a key role in the synthesis of some plastic plasticizers, improving the flexibility and durability of plastics, thereby enhancing their performance

Synthetic resins

High-performance resins: Pyromellitic anhydride is used to synthesize polyurethane resins and epoxy resins, which are widely used in the manufacture of coatings, elastomers and high-strength materials.

Chemical intermediates

Organic synthesis: As a chemical intermediate, pyromellitic anhydride participates in the synthesis of aromatic compounds and polymer materials.

Storage conditions: Store in a cool and dry place, away from heat, sunlight and heat sources
