Description

Propyleneoxide Polymer With Phthalic Anhydride, Maleic Anhydride And Ethyleneglycol is a specialized polymeric resin, commonly known as an unsaturated polyester, synthesized from key monomers including propylene oxide. This compound is valued for its ability to form durable, cross-linked thermoset plastics with excellent mechanical and chemical resistance properties. It is primarily required by manufacturers in the coatings, adhesives, and composite materials industries seeking high-performance polymeric binders and matrix resins.

Application

• As a reactive resin precursor for the formulation of unsaturated polyester resins (UPR).
• As a key polymeric component in the production of fiberglass-reinforced plastics (FRP) for automotive parts, marine hulls, and construction panels.
• In the manufacture of gel coats and topcoats to provide a smooth, protective finish on composite surfaces.
• As a binding agent or matrix material in industrial adhesives and sealants.
• For the production of corrosion-resistant tank linings and pipes in chemical processing plants.
• In the formulation of electrical insulation components and potting compounds.
• As a raw material for synthetic marble and cultured stone products.

Quality Control

Our production of this polymeric resin adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as acid value, hydroxyl value, viscosity, and reactivity are rigorously monitored. Certificates of Analysis (COA) detailing specific lot specifications are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat sources, open flames, and incompatible materials such as strong oxidizing agents. For long-term storage, consider under an inert atmosphere to prevent premature cross-linking or gelation.
