Description

Allyloxy-Hydroxypropyl-Hydroxyethylcellulose is a chemically modified cellulose ether, specifically engineered to introduce reactive allyl groups onto the hydroxypropyl hydroxyethylcellulose (HPHEC) backbone. This unique modification is crucial for applications requiring subsequent cross-linking or polymerization, enhancing the material's functionality in advanced formulations. It is primarily sought by manufacturers in the coatings, adhesives, and specialty polymer industries where tailored rheology and permanent network formation are key performance drivers.

Application

• Reactive Thickener & Rheology Modifier in UV-curable coatings, inks, and adhesives, where the allyl groups participate in the curing process.
• Cross-linkable Binder for the production of high-performance, water-resistant films and membranes.
• Stabilizer and Protective Colloid in emulsion and dispersion polymerization, providing steric stabilization.
• Gelation Agent in personal care and cosmetic products that require in-situ gel formation upon curing.
• Pharmaceutical Excipient for controlled-release matrix tablets, where it can be cross-linked to modulate drug release profiles.
• Additive in Ceramic and Cementitious Materials to improve workability and green strength, with potential for later-stage modification.

Quality Control

Our Allyloxy-Hydroxypropyl-Hydroxyethylcellulose is manufactured under a stringent quality management system. Each batch is tested to ensure consistent substitution levels, viscosity, and reactivity. While specific grades may be developed for target applications, our standard quality assurance includes verification of key parameters. Certificates of Analysis (COA) detailing purity, degree of substitution, and physical specifications are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Keep the container tightly sealed when not in use to prevent moisture absorption, which can affect product performance.
