Description

D-Glucitol, Reaction Products With Epichlorohydrin is a polyol-based polymer derived from the reaction of sorbitol (D-glucitol) with epichlorohydrin, forming a versatile cross-linked polyether polyol. This compound is valued for its ability to act as a reactive intermediate, cross-linking agent, and modifier, imparting flexibility, hydrophilicity, and chemical resistance to final materials. It is primarily utilized by formulators and manufacturers in the production of specialty resins, coatings, adhesives, and as a component in pharmaceutical and personal care applications where biocompatibility and polyol functionality are required.

Application

• Epoxy Resin Modifier: Used as a flexibilizer and toughening agent in epoxy resin systems for coatings, composites, and adhesives.
• Polyurethane Cross-linker: Serves as a polyol component in polyurethane formulations to enhance elasticity and moisture resistance in foams and elastomers.
• Pharmaceutical Excipient: Employed as a matrix former or binder in controlled-release drug delivery systems due to its biocompatible polyol structure.
• Personal Care Ingredients: Functions as a humectant and film-forming agent in cosmetic and skincare formulations.
• Ion-Exchange Resin Precursor: Acts as a backbone for the synthesis of specialty ion-exchange resins used in water treatment and purification.
• Textile & Paper Chemical: Utilized as a cross-linking agent for cellulose fibers to improve wet-strength and durability.
• Adhesive & Sealant Formulation: Incorporated to improve adhesion and flexibility in various industrial adhesive and sealant products.

Quality Control

Our production of D-Glucitol, Reaction Products With Epichlorohydrin adheres to stringent quality management protocols. Each batch is characterized for critical parameters including hydroxyl value, epoxy equivalent weight, viscosity, and residual epichlorohydrin content to ensure consistency and performance. Certificates of Analysis (COA) documenting these specifications are available upon request, supporting compliance for use in regulated industries.

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 to prevent moisture absorption, which can affect product properties.
