Description

Bis(Methylbenzylidene)Sorbitol CAS NO 87826-41-3 is a high-performance organogelator and clarifying agent widely used in polymer processing. This compound is valued for its ability to form a nanofibrillar network that effectively gels organic solvents and nucleates polymers, leading to improved optical and mechanical properties. It is an essential additive for manufacturers in the plastics, coatings, and personal care industries seeking to enhance product clarity, dimensional stability, and processing characteristics.

Application

• Polymer Clarifying Agent: Primary nucleating agent for polypropylene (PP) to improve transparency, gloss, and stiffness.
• Gel Formation: Used to create stable organogels in various solvents for applications in coatings, adhesives, and specialty formulations.
• Rheology Modifier: Controls viscosity and provides thixotropic properties in solvent-based systems and personal care products.
• Processing Aid: Enhances the crystallization rate of polymers, reducing cycle times in injection molding and extrusion processes.
• Surface Modifier: Improves the surface finish and reduces haze in clear plastic films and containers.
• Thermal Stabilizer: Contributes to improved heat distortion temperature in nucleated polymer compounds.

Quality Control

Our Bis(Methylbenzylidene)Sorbitol is manufactured under a strict quality management system to ensure batch-to-batch consistency and high performance. Each lot undergoes comprehensive analytical testing, including assay, melting point, and purity profiling, to meet the stringent requirements of the polymer industry. A Certificate of Analysis (COA) documenting all key parameters is provided with every shipment to guarantee compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after initial use to prevent moisture absorption, which can affect performance.
