Description

Ethenol, Homopolymer, Degraded is a chemically modified form of polyvinyl alcohol (PVOH), characterized by a reduced molecular weight and altered physical properties. This specialized grade is engineered to offer enhanced solubility and tailored rheological behavior for demanding industrial formulations. It is a critical raw material for manufacturers in sectors such as adhesives, paper coatings, textiles, and construction chemicals, where controlled viscosity and film-forming characteristics are paramount.

Application

• Adhesive Formulations: Acts as a key binder and rheology modifier in water-based adhesives for paper, wood, and packaging.
• Paper & Paperboard Coatings: Used in barrier coatings and surface sizing to improve strength, printability, and oil/grease resistance.
• Textile Sizing & Finishing: Provides a temporary protective film on yarns during weaving and can be used in fabric finishing applications.
• Construction Chemicals: Serves as a water-retention agent and workability aid in cement-based tile adhesives, grouts, and self-leveling compounds.
• Polymerization Aid: Functions as a protective colloid and stabilizer in the emulsion polymerization of vinyl acetate and other monomers.
• Film-Forming Applications: Utilized in the production of water-soluble films for agrochemical packaging, detergent pods, and other controlled-release systems.

Quality Control

Our Ethenol, Homopolymer, Degraded is manufactured under a stringent quality management system. Each batch is tested against critical parameters including degree of hydrolysis, viscosity, and residual acetate content to ensure batch-to-batch consistency and performance reliability. Certificates of Analysis (COA) documenting these specifications are provided with every shipment.

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); containers must be kept tightly sealed after initial use to prevent caking and property changes due to moisture absorption.
