Description

Proteins, Soy, Phthalated CAS NO 72245-15-9 is a chemically modified soy protein derivative where phthalic anhydride is used to introduce phthalate groups onto the protein backbone. This modification is crucial as it significantly enhances the material's properties, making it more suitable for specialized industrial applications that require improved solubility, film-forming ability, or compatibility with synthetic polymers. This product is primarily needed by manufacturers in the adhesives, coatings, biodegradable plastics, and specialty chemical sectors seeking bio-based performance additives.

Application

• As a bio-based modifier and plasticizer in adhesive formulations to improve flexibility and bond strength.
• As a functional additive in water-based coatings and paints to enhance film formation and substrate adhesion.
• As a component in the production of biodegradable and composite materials, offering a renewable alternative to fully synthetic polymers.
• In the formulation of encapsulation matrices for controlled-release agrochemicals or pharmaceuticals.
• As a textile finishing agent to impart specific functional properties to fabrics.
• For research and development of novel bio-derived polymers with tailored mechanical and chemical characteristics.

Quality Control

Our Proteins, Soy, Phthalated is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance and meets agreed-upon specifications for parameters such as degree of substitution, viscosity, and solubility. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance protocols.

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). This material is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent moisture absorption which may affect product performance.
