Polyvinyl Alcohol Cold-Hot Powder, Grade : Industrial Grade

Polyvinyl Alcohol (PVA) Cold-Hot Powder is a water-soluble synthetic polymer, often used in various industrial and commercial applications due to its excellent film-forming, emulsifying, and adhesive properties. The "cold-hot " designation refers to the powder 's solubility in both cold and hot water, making it versatile for different processes. Key Characteristics: Chemical Formula: (C₂H₄O)n (where 'n ' represents the degree of polymerization) Appearance: White or off-white powder. Solubility: Soluble in cold and hot water, forming a clear and viscous solution. Film-Forming Ability: PVA forms strong, flexible, and transparent films, which are resistant to oils, greases, and solvents. pH: Neutral to slightly acidic. Uses: Textiles: Used as a sizing agent and a fiber binder in the textile industry. Adhesives: PVA is used in making adhesives, particularly for paper, wood, and other porous materials. Packaging: Employed in water-soluble packaging films, which dissolve upon contact with water. Paper Coatings: Used in paper coatings to improve surface strength and ink receptivity. Safety: PVA is generally considered non-toxic and is safe for use in various consumer products. However, like all powders, it can cause respiratory irritation if inhaled, so handling in well-ventilated areas or using protective equipment like masks is advisable.
