Description

Fumaric Acid,Polymer With Propyleneglycol,And 3-Oxa-1,5-Pentanediol CAS NO 42556-67-2 is a specialized polymeric ester derived from fumaric acid, offering a unique combination of reactive sites and structural flexibility. This engineered polymer is valued for its ability to act as a versatile building block or modifier in advanced material synthesis. It is primarily targeted for industrial applications requiring custom-tailored polymeric backbones, such as in the formulation of high-performance resins, coatings, and specialty adhesives.

Application

• Polymer Synthesis: Serves as a key monomer or co-monomer for creating unsaturated polyester resins (UPR) with specific mechanical and thermal properties.
• Coating & Ink Formulations: Used as a reactive diluent or cross-linking agent in radiation-curable coatings, inks, and overprint varnishes to enhance film hardness and chemical resistance.
• Adhesive & Sealant Production: Incorporated into structural and pressure-sensitive adhesive formulations to improve flexibility, adhesion, and durability.
• Composite Materials: Acts as a matrix resin component in fiber-reinforced plastics (FRP) for automotive and construction applications.
• Biomedical Materials: Investigated for use in the development of biodegradable polymers and drug delivery systems due to its fumarate-based, hydrolysable backbone.
• Specialty Chemical Intermediates: Utilized as a precursor for further chemical modifications to create surfactants, plasticizers, or other functional polymers.

Quality Control

Our production of this specialty polymer adheres to strict quality management protocols. Each batch is characterized for critical parameters including acid value, hydroxyl value, viscosity, and residual monomer content to ensure batch-to-batch consistency. Certificates of Analysis (COA) detailing these specifications are provided and can be tailored to meet specific customer requirements and application standards.

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). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product properties. Keep away from strong oxidizers and heat sources.
