Product DescriptionPolyvinyl Alcohol (PVA)Polyvinyl Alcohol (PVA), is a water-soluble synthetic polymer renowned for its exceptional versatility, biodegradability, and outstanding physicochemical properties. It is produced through the hydrolysis of polyvinyl acetate, resulting in a polymer whose specific characteristics—such as solubility, viscosity, and adhesion strength—can be precisely tailored by adjusting its degree of hydrolysis and polymerization. This adaptability makes PVA an indispensable material across a wide spectrum of industries.This unique combination of tunable properties, environmental compatibility, and multifunctionality establishes PVA as a critical performance polymer in fields ranging from specialty adhesives and advanced packaging to construction materials and textile processing.Key Features & AdvantagesPVA boasts a unique combination of properties: it forms strong, flexible, and transparent films; exhibits excellent adhesive strength; and is resistant to oils, solvents, and greases. Its high oxygen barrier properties further enhance its utility in packaging. As a non-toxic and biodegradable polymer, PVA is also an environmentally conscious choice for modern applications.Technical SpecificationsPVA is typically characterized by its degree of hydrolysis (ranging from partially hydrolyzedProduct NamePolyvinyl AlcoholFormFree-Flowing PowderColorWhite to Off-WhiteAsh Content≤ 0.7%Functional Properties and AdvantagesPVA possesses an exceptional combination of physicochemical properties that make it indispensable across industries:√ Film-Forming Capability: Forms strong, flexible, and highly transparent films with outstanding oxygen barrier properties (when dry)√ Adhesive Strength: Demonstrates excellent adhesion to porous surfaces like paper, wood, and textiles√ Solubility Characteristics: Water-soluble at specific temperatures, with solubility tunable through hydrolysis degree√ Chemical Resistance: Resistant to oils, greases, and organic solvents√ Biodegradability: Undergoes microbial degradation in soil and water environments√ Emulsifying & Suspending Ability: Effectively stabilizes emulsions and suspensionsApplicationsAdhesives & BindersTextilesPVA serves as a primary component in formulating high-performance adhesives for paper, packaging, and wood industries. Its excellent film-forming ability and strong adhesion to cellulose materials make it ideal for:√ Corrugated cardboard manufacturing√ Paper bag seam adhesives√ Bookbinding glues√ Wood composite binders√ Envelope gummingThe polymer's tunable viscosity and quick-setting characteristics enable production of adhesives with precisely controlled open time and bond strength.In textile processing, PVA functions as an essential warp sizing agent and finishing auxiliary:√ Provides protective coating for yarns during weaving operations√ Reduces yarn breakage and improves loom efficiency√ Easily removed during desizing due to its water solubility√ Serves as a temporary stiffener for fabrics√ Acts as a non-ionic assistant in dyeing processesPaints & CoatingsPaper IndustryPVA contributes significantly to water-based coating systems through:√ Pigment suspension stabilization in aqueous paints√ Viscosity modification in emulsion paints√ Improving brushability and flow characteristics√ Enhancing adhesion to chalky surfaces√ Serving as a protective colloid in PVAc emulsion polymerizationPVA revolutionizes paper processing through:√ Surface sizing applications for improved printability√ Coat weight control in coating formulations√ Enhanced ink receptivity and reduced feathering√ Increased paper strength and surface smoothness√ Oil and grease resistance for specialty packaging papersConstructionPackaging FilmsPVA modifies cementitious systems by:√ Improving mortar workability and water retention√ Enhancing adhesion to substrates√ Reducing dusting in dry-mix formulations√ Increasing flexural strength of cement composites√ Reducing shrinkage cracking in repair mortarsPVA enables advanced packaging solutions through:√ Water-soluble detergent packets and agrochemical bags√ Biodegradable packaging alternatives√ Oxygen barrier layers in multi-layer structures√ Dissolvable laundry bags for healthcare applications√ Edible food packaging filmsPackaging & StoragePackaging: 25 kg/bag, 500 kg/pallet, or customized packaging.Storage: Store in a cool, dry place away from moisture.Shelf Life: 24 months in sealed original packaging.Company ProfileShenyang Xingzhenghe Chemical Co., Ltd.Founded in 2009, Shenyang Xingzhenghe Chemical Co., Ltd. has grown into a nationally recognized high-tech enterprise specializing in the research, development, and production of premium fine chemicals.
