  • What are the applications of PVA in agriculture?
    Aug 20, 2020
      Polyvinyl alcohol (PVA) has several applications in agriculture, including:   1. Seed coating: PVA can be used as a seed coating material to enhance germination, improve seedling growth, and provide protection against pests and diseases.   2. Soil stabilizer: PVA can be added to soil to improve its structure and stability, especially in erosion-prone areas. It helps reduce soil erosion, increase water retention, and enhance soil fertility.   3. Mulching film: PVA films can be used as mulching materials to cover the soil around plants. This helps to conserve moisture, control weed growth, and maintain stable soil temperatures, leading to improved plant growth and higher crop yields.   4. Slow-release fertilizers: PVA can be incorporated into fertilizer formulations to create slow-release or controlled-release fertilizers. This allows nutrients to be released gradually over time, providing sustained nutrition to plants and minimizing nutrient leaching.   5. Crop protection: PVA can be used as a component in biodegradable agricultural films for crop protection purposes. These films can be used for insect barriers, weed control, and microbial resistance, reducing the reliance on conventional plastic films.   6. Hydrogel applications: PVA hydrogels have been utilized in agriculture for various purposes, such as water retention in drought-prone areas, as carriers for controlled release of agrochemicals, and as bio-based materials for seed germination and plant growth.   These applications demonstrate the versatility of PVA in agriculture, providing solutions for improving plant growth, conserving resources, and promoting sustainable farming practices.   Website: www.elephchem.com Whatsapp: (+)86 13851435272 E-mail: admin@elephchem.com ElephChem Holding Limited, professional market expert in Polyvinyl Alcohol(PVA) and Vinyl Acetate–ethylene Copolymer Emulsion(VAE) with strong recognition and excellent plant facilities of international standards.

  • Application of Polyvinyl Alcohol(PVA) in films
    Aug 08, 2020
    Polyvinyl alcohol (PVA) has various applications in the film industry. Here are some of the common applications of PVA in films:   1. Water-soluble film: PVA can be used to produce water-soluble films that are used for packaging various products such as detergents, agrochemicals, and personal care products. These films dissolve in water, providing convenience and reducing waste.   2. Food packaging film: PVA can be used as a coating or component in food packaging films. It provides excellent oxygen barrier properties, moisture resistance, and aroma retention, helping to extend the shelf life of food products.   3. Biodegradable film: PVA can be used to produce biodegradable films that are environmentally friendly. These films can replace traditional plastic films in applications such as mulch films, agricultural films, and compostable packaging materials.   4. Drug delivery films: PVA films can be used as drug delivery systems in the pharmaceutical industry. These films can be loaded with active pharmaceutical ingredients and used for transdermal patches, oral dissolvable films, or other drug delivery applications.   5. Optical film: PVA can be used in the production of optical films for applications such as LCD displays and optical lenses. These films provide excellent optical clarity, high transparency, and low birefringence.   6. Photographic film: PVA has been widely used in the production of photographic films. It acts as a binder and protective coating, ensuring adhesion of the photo emulsion to the film base and providing surface protection.   Overall, PVA has versatile properties that make it suitable for a wide range of film applications, including water-soluble films, food packaging films, biodegradable films, drug delivery films, optical films, and photographic films.   Website: www.elephchem.com Whatsapp: (+)86 13851435272 E-mail: admin@elephchem.com ElephChem Holding Limited, professional market expert in Polyvinyl Alcohol(PVA) and Vinyl Acetate–ethylene Copolymer Emulsion(VAE) with strong recognition and excellent plant facilities of international standards.   PVA 088-50 & PVA 24-88 Polyvinyl alcohol PVA 088-20 & PVA 17-88 Polyvinyl alcohol PVA 100-27 & PVA 1799 Polyvinyl alcohol

  • Application of PVA in paper industry
    Aug 02, 2020
    Polyvinyl alcohol (PVA) is widely used in the paper industry due to its excellent film-forming and adhesive properties. PVA is typically used in the paper manufacturing process as a binder, coating agent, or surface sizing agent. Here are some common applications of PVA in the paper industry:   1.Surface Sizing: PVA is used as a surface sizing agent to improve the surface properties of paper, such as its smoothness, printability, and water resistance. It forms a thin film on the surface of the paper, reducing the penetration of liquids and improving the ink receptivity.   2. Binder for Coatings: PVA is used as a binder in the formulation of coatings applied to paper surfaces. It helps in binding pigments and other additives to the paper, enhancing the color retention, gloss, and overall performance of the coatings.   3. Adhesive for Paperboard: PVA is utilized as an adhesive in the production of paperboard and cardboard boxes. It provides excellent adhesion between the layers of paper, improving the overall strength and durability of the packaging materials.   4. Release Agent: PVA can be used as a release agent in the paper industry. It is applied to the surfaces of rollers and machinery to prevent sticking and improve the smooth flow of paper during the production process.   5. Fiber Treatment: PVA can be applied to paper fibers to improve their bonding properties and enhance the paper's strength and tear resistance.   It's important to note that the specific grade of PVA used in the paper industry may vary depending on the desired properties and requirements of the paper or paperboard being produced.   Website: www.elephchem.com Whatsapp: (+)86 13851435272 E-mail: admin@elephchem.com ElephChem Holding Limited, professional market expert in Polyvinyl Alcohol(PVA) and Vinyl Acetate–ethylene Copolymer Emulsion(VAE) with strong recognition and excellent plant facilities of international standards.

  • Water soluble pva film
    May 28, 2020
    Water-soluble PVA film refers to a thin film made of polyvinyl alcohol (PVA) that can dissolve in water. PVA is a synthetic polymer that exhibits excellent solubility in water, making it suitable for various applications where easy dissolution is desired.   Water-soluble PVA film has several uses and advantages: 1. Packaging: PVA film is used in the packaging industry, particularly for products that require single-use or dissolvable packaging, such as detergent pods, dishwasher tabs, and personal care products. The film dissolves upon contact with water, eliminating the need for manual unwrapping or disposal.   2. Agriculture: PVA film is employed in agriculture as a biodegradable and water-soluble alternative to traditional plastic mulch films. It can be used to cover crops or seedlings, providing moisture retention, weed suppression, and improved germination, and it naturally degrades over time without leaving behind harmful residue.   3. Education and experimentation: Water-soluble PVA film is often utilized in educational settings and scientific experiments as a safe and convenient material. It can be used for demonstrations, encapsulation of ingredients, or as a release agent for molds, as the film dissolves easily in water.   4. Construction: PVA film finds applications in the construction industry, primarily in the creation of temporary supports or molds for concrete structures. The film can be wrapped around objects or used as a barrier, and once the concrete has set, the film can be dissolved with water, leaving a clean surface.   The biodegradability of PVA film is attributed to the water-soluble nature of PVA. When the film comes into contact with water, the water molecules penetrate and weaken the intermolecular forces holding the polymer chains together, leading to the dissolution and ultimate breakdown of the film into harmless substances.   Website: www.elephchem.com Whatsapp: (+)86 13851435272 E-mail: admin@elephchem.com ElephChem Holding Limited, professional market expert in Polyvinyl Alcohol(PVA) and Vinyl Acetate–ethylene Copolymer Emulsion(VAE) with strong recognition and excellent plant facilities of international standards.
