Polyvinyl Alcohol (PVA) BP 05

What is Polyvinyl alcohol?

Polyvinyl alcohol (PVA) is a synthetic polymer that is soluble in water. It is produced by the polymerization of vinyl acetate and subsequent hydrolysis of the polymer. The hydrolysis process converts the acetate groups into alcohol groups, resulting in a polymeric chain with repeating alcohol units.
PVA is known for its excellent film-forming and adhesive properties. It is often used as a component in adhesives, coatings, and films. PVA films are transparent and have a high tensile strength, making them useful for various applications. PVA is also biodegradable, which adds to its appeal in environmentally friendly applications. One of the notable characteristics of PVA is its water solubility. When in contact with water, PVA dissolves, forming a viscous solution. This property makes PVA widely used in applications such as textile sizing, paper coatings, and as a component in detergents and personal care products.

In addition to its solubility, PVA exhibits good chemical resistance, making it suitable for use in coatings and barriers. It is also resistant to oils, greases, and organic solvents. These properties make PVA versatile and applicable in various industries, including packaging, textiles, paper, construction, and pharmaceuticals.

Furthermore, PVA can be crosslinked with certain agents to enhance its properties further. Crosslinked PVA exhibits improved mechanical strength, thermal stability, and water resistance, making it useful in applications such as membranes, gels, and drug delivery systems.

Overall, polyvinyl alcohol is a versatile polymer with a wide range of applications due to its film-forming, adhesive, solubility, and chemical resistance properties.

CCP PVA BP-05 Applications:

CCP PVA BP-05 is a high-performance polyvinyl alcohol (PVA) resin with a degree of alcoholysis of 87.0%~89.0% and moderate low viscosity. Endowed with excellent water solubility, film-forming properties, and adhesion, this synthetic polymer is tailored for diverse industrial applications.

1. Adhesives: CCP PVA BP-05 is widely incorporated into adhesive formulations, delivering reliable bonding strength to porous materials such as paper, fabric, and wood-based panels. It is particularly suitable for water-based adhesives in paper bonding, construction adhesives, and protective colloids for redispersible polymer powders, offering good compatibility with other additives.

2. Water-Based Coatings: This PVA resin serves as a core component in water-based coatings and paints. It provides superior film-forming ability, strong substrate adhesion, and enhanced scrub resistance, making it ideal for paper coatings, textile coatings, and architectural decorative coatings that require environmental friendliness and low VOC emissions.

3. Textile Industry: As a high-efficiency warp sizing agent, CCP PVA BP-05 is extensively used in the textile sector. It strengthens and protects warp yarns (cotton, polyester-cotton, viscose filaments, etc.) during weaving, improving weaving efficiency and reducing yarn breakage. Its easy desizing property ensures no residue on fabrics during subsequent processing.

4. Paper Industry: CCP PVA BP-05 acts as a critical additive in papermaking, including surface sizing and pigment coating binders. It enhances paper smoothness, printability, and ink resistance, while improving the paper’s mechanical strength and water resistance—suitable for high-quality printing paper, packaging paper, and specialty paper production.

5. Biodegradable Films: Leveraging its eco-friendly and film-forming characteristics, CCP PVA BP-05 is a key raw material for biodegradable films. The films produced are transparent, flexible, and moisture-resistant, applicable for food packaging, agricultural mulch films, and disposable packaging materials that meet green environmental standards.

6. Emulsifiers & Dispersants: This PVA resin functions effectively as an emulsifier and dispersant in various formulations. It stabilizes emulsions and suspensions, ensuring uniform dispersion of ingredients in paints, inks, and agricultural chemicals, thereby enhancing product stability and performance.

7. Pharmaceutical & Cosmetic Industries: CCP PVA BP-05 is utilized in pharmaceutical and cosmetic products due to its non-toxicity and biocompatibility. It serves as a film-forming agent in facial masks, a thickener in ointments, and a moisture-retention component in personal care products, contributing to product texture and efficacy.
