Description

1,3:2,4-Bis(3,4-Dimethylobenzylideno) Sorbitol is a highly effective organogelator and clarifying agent widely used in polymer processing. This compound is valued for its ability to form nanofibrillar networks, which efficiently nucleate and clarify polyolefins and other polymers. It is an essential additive for manufacturers in the plastics, packaging, and specialty chemical industries seeking to enhance product transparency and physical properties.

Application

• Polymer Clarifying Agent: Primary nucleating agent for improving the clarity and gloss of isotactic polypropylene (iPP) in food packaging, consumer goods, and medical devices.
• Gelation and Rheology Modifier: Used to gel organic solvents and oils for applications in cosmetics, personal care formulations, and specialty coatings.
• Nucleating Agent for Crystallization: Enhances crystallization rate and temperature in polymers, leading to shorter cycle times and improved mechanical properties in injection molding.
• Thermoplastic Processing Aid: Improves processability and surface finish in the production of films, fibers, and molded articles.
• Research & Development: Serves as a model compound in materials science for studying supramolecular gelation and polymer nucleation mechanisms.

Quality Control

Our 1,3:2,4-Bis(3,4-Dimethylobenzylideno) Sorbitol is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, performance, and consistency. A comprehensive Certificate of Analysis (COA) documenting identity, assay, and impurity profiles is provided with every shipment to guarantee compliance with your technical requirements.

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); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect performance.
