  • PVA is safe and environmentally friendly.
    Feb 26, 2020
    Polyvinyl alcohol (PVA) is generally considered safe and environmentally friendly. It is non-toxic, biodegradable, and does not release harmful substances during use or decomposition. PVA is derived from renewable resources, such as petroleum or natural gas, and it can be produced with minimal environmental impact.   PVA's biodegradability means that it can break down naturally over time, reducing its potential impact on ecosystems. However, its rate of biodegradation depends on various factors such as temperature, humidity, and microbial activity in the environment. In general, PVA is considered to degrade at a moderate rate compared to some other materials.   Polyvinyl alcohol is not considered a microplastic. Microplastics are typically tiny plastic particles measuring less than 5 mm in size and are often created from the breakdown of larger plastic materials or the direct release of small plastic particles. PVA, on the other hand, is a water-soluble synthetic polymer derived from polyvinyl acetate through a hydrolysis process. When PVA is exposed to water or moisture, it dissolves completely, unlike microplastics that persist in the environment.   In summary, PVA is generally considered a safe and climate-friendly material due to its biodegradability, low toxicity, and minimal environmental impact during production. However, as with any material, responsible use and proper disposal practices are essential to ensure its environmental sustainability.   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.

  • How to make PVA dissolve faster?
    Feb 18, 2020
    To make PVA dissolve faster, you can try the following methods:   Increase the water temperature: Warmer water helps to accelerate the dissolution of PVA. Heat the water to a moderate temperature, but avoid using boiling water as it may denature the PVA.   Stir or agitate the solution: Stirring or agitating the PVA solution can enhance the dissolution process by increasing the contact between the PVA particles and water. Use a stirring rod or mixer to create turbulence in the solution.   Use smaller PVA particles: If your PVA is in the form of solid particles or granules, consider grinding or crushing them into smaller particles before adding them to the water. Smaller particles have a larger surface area, which facilitates faster dissolution.   Use water with a lower pH: Lowering the pH of the water slightly can help to improve the solubility of PVA. However, avoid using strongly acidic solutions, as they may degrade the PVA.   Increase the water-to-PVA ratio: Using a higher volume of water in proportion to the amount of PVA can aid in faster dissolution. This allows for better dispersion and interaction between PVA and water molecules.   Remember to follow the specific instructions provided by the manufacturer for the particular PVA product you are using, as they may have specific recommendations for optimal dissolution.   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.
