Polyvinyl alcohol 2888

Polyvinyl alcohol 2488 (PVA 2488) Polyvinyl alcohol 2488, known for its excellent performance and wide application, is a white or slightly yellow powdery substance with unique physical and chemical properties. Features: Solubility: Polyvinyl alcohol 2488 dissolves in hot water to form a colloidal solution and has good affinity for water. Chemical resistance: It is resistant to mineral oils, greases, lubricants and most organic solvents, showing excellent chemical stability. Thermal stability: Polyvinyl alcohol 2488 dehydrates and decomposes at about 150°C, and its color turns yellow, with good thermal stability. Environmental protection: As a water-soluble and environmentally friendly polymer, polyvinyl alcohol 2488 can be rapidly hydrolyzed and decomposed in the natural environment, which is environmentally friendly. Application areas: Textile industry: As an adhesive in textile slurry, it improves the firmness, flatness and softness of the fiber, and enhances the uniformity and fullness of the dyeing effect. Papermaking industry: As a paper enhancer, it increases the strength and durability of paper, improves tensile strength and tear strength, and reduces water absorption and permeability. Plastic industry: As a plasticizer, it improves the softness and cold resistance of plastics and is used to make various plastic films, such as food bags and agricultural covering films. Adhesive field: It is used to make water-based adhesives, has excellent adhesion and water resistance, and is suitable for bonding and coating of various materials. Safety: Polyvinyl alcohol 2488 is generally a non-toxic material, but its dust is irritating to the respiratory tract. Inhalation, ingestion or skin contact with the substance can cause delayed reactions. Workers should take good protection and immediately rinse with running water when touching their eyes and skin. Polyvinyl alcohol 2488 has become one of the indispensable materials in the chemical industry with its unique properties and wide application.
