Product Description Product DescriptionPVA RESIN Cold water instant high viscosity high transparent PVA 2488 powder PVA glue spray Product's main characteristics: Polyvinyl alcohol resin series products are white solid, the appearance is divided into flocculent, granular, powder three kinds: non-toxic, tasteless, pollution-free, can be dissolved in 80-90 oC water. The aqueous solution has good adhesion and film-forming properties. Resistant to most organic solvents such as oils, lubricants and hydrocarbons; It has the chemical properties of esterification, etherification and acetalization of long chain polyols. Detailed PhotosAPPLICATION 1. Warp sizing agent. For warp sizing or fabric finishing. 2. Paper processing. PVA has strong adhesive force and forms a tough film. It can be used to replace starch and casein or be used in combination with them as a color carrier for coated paper, or as a sizing agent to apply surface sizing to copperplate paper, wear-resistant paper, blueprint base paper, kraft paper, etc. This can enhance the paper's wear resistance, folding endurance, tear resistance, and improve its glossiness, smoothness, and printability. 3. Adhesive. A series of adhesives made mainly from PVA have good adhesive force on paper, cloth and wood. Some inorganic substances, such as clay, bentonite, alumina and titanium dioxide, can be added to increase the bonding strength. 4. Film. The film made of PVA has good transparency, high tensile and tear strength, good moisture permeability and heat insulation, is resistant to oil and organic solvents, and does not generate static electricity. Therefore, it is suitable for packaging textiles and food. 5. Acetal derivatives. PVA reacts with formaldehyde, acetaldehyde, butyraldehyde or other aldehydes in the presence of an acid catalyst to form acetalized PVA derivatives, which further improve the water resistance and adhesiveness of polyvinyl alcohol. 6. Fiber raw materials. Viscose rayon fibers are produced by washing PVA with water, dissolving it, spinning it, and then formaldehyde treatment. PVA can also be used to develop and manufacture high-strength and high-modulus PVA fibers to replace asbestos. 7. Dry-mixed mortar. PVA has excellent film-forming properties. When used in combination with cellulose ether-based water-retaining agents, they can enhance the flexibility and water retention of cement mortar and gypsum building materials, and improve the adhesion of mortar. main PVA products1.

Polyvinyl alcohol resin series products can be dissolved in hot water below 95oC, but due to the difference in polymerization degree, alcoholysis degree, alcohol hydrolysis methods and other different in the dissolution time, temperature has a certain difference, so in the use of different brands of polyvinyl alcohol resin, the dissolution method and time need to explore. When dissolved, the product can be slowly added to the cold water of about 20 ° C while stirring to fully swell, disperse and escape volatile materials (do not add the product to the water above 40 ° C for direct dissolution, to avoid the phenomenon of coating and skin dissolution), and then heat up to about 95 ° C to accelerate the dissolution, and hold heat for 2~2.5 hours. Until the solution no longer contains small particles, and then through 28 mesh stainless steel filter impurities, can be used.2. Stirring speed 70~100 RPM, when heating, can be used jacket, water bath and other indirect heating, can also be used direct heating of water steam: however, can not use direct heating of open flame, so as to avoid local overheating and decomposition, if there is no mixer, steam can be used to blow into the method of tangential direction to dissolve. The aqueous solution concentration of polyvinyl alcohol resin series products is generally below 12~14%; The aqueous solution concentration of low alcoholysis polyvinyl alcohol resin products can generally be about 20%.3. Test whether the product is completely dissolved: take out a small amount of solution, add 1 to 2 drops of iodine solution, if there is a blue granular transparent body, indicating that it has not been completely dissolved, such as the color can be evenly spread, indicating that it has been completely dissolved.Tips:Color classification has nothing to do with the product, just for the convenience of purchasing models and releasing products! Polyvinyl alcohol is white powder or granular or flocculent before dissolution, according to the weight model shipped, completely dissolved is a transparent solution! 88 Series model powder can be dissolved in cold water! 99 series models and particle floc need to be heated to dissolve,99 model powder also need to be heated, powder undissolved faster!Viscosity 0388 0588 1788 2488 2688 Viscosity from low to high!Viscosity 1792 0599 1799 2399 2499 2699 Viscosity from low to high, only 88 model powder can be dissolved in cold water!The cold soluble type has 0588 1788 2488 2688 powder (80-160 mesh, 100 mesh is recommended for direct water dissolution), the viscosity is from low to high, and the direct dry powder mixing type is recommended for 120 mesh. The rest should be heated and dissolved!Certification Packaging & ShippingContact Us: Get in touch to start our collaboration today.When it comes to packaging, transportation, and storage, it is important to ensure the proper handling of polyvinyl alcohol. Here are some key points to consider:Packaging: Polyvinyl alcohol is typically packaged in white flocculent, flaky, or powdery solid forms. It is classified as a non-dangerous, non-explosive, non-oxidizing, non-corrosive, non-radioactive, and non-toxic product. Packaging options include plastic woven bags or paper bags weighing 12.5kg, 20kg, or 25kg. Alternatively, larger quantities can be stored in plastic woven jumbo bags ranging from 750kg to 1000kg.Transportation: During transportation, it is essential to employ clean means of transport to prevent moisture, rain, and excessive exposure to sunlight. Careful handling is crucial to avoid scratching or damaging the packaging.Storage: To maintain the quality of polyvinyl alcohol, it should be stored in a dry and well-ventilated room with a temperature ranging between 5°C and 30°C. It is imperative to keep it away from heat sources, moisture, and direct sunlight. Additionally, storing PVA together with volatile chemicals should be strictly avoided to prevent adsorption and potential deterioration.Company Profile Hebei Chijiang Import and Export Co., Ltd. is a professional, agile and international plastics chemical supplier, specialising in the plastics and its products industry for more than 10 years, with the most complete international supply chain of plastics raw materials.
