  • 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.

  • What does polyvinyl alcohol do to the body?
    Jan 20, 2020
    Polyvinyl alcohol (PVA) is generally considered safe for use in various applications and has low toxicity. When consumed orally, PVA is not absorbed by the body and passes through the digestive system without being metabolized. It is essentially inert and does not have any nutritional value.   Since PVA is water-soluble, excessive ingestion of large amounts could potentially cause gastrointestinal discomfort, such as bloating or diarrhea. However, it is worth noting that PVA is not intended for consumption and is not a food ingredient.   In medical and pharmaceutical applications, Polyvinyl alcohol is used in various forms, including eye drops, contact lenses, and drug delivery systems. In these cases, PVA is designed to be safe for specific uses and is tested and regulated accordingly.   As with any substance, it is important to use PVA in accordance with its intended purpose and follow safety guidelines provided by manufacturers. If you have specific concerns or questions about the use of PVA or any other substance, it is recommended to consult with a healthcare professional.   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.

  • What is VAM material?
    Jan 13, 2020
    VAM stands for Vinyl Acetate Monomer. It is a key raw material used in the production of various polymers and copolymers. Vinyl acetate monomer is a clear liquid with a distinct odor. It is primarily derived from the reaction between acetylene and acetic acid.   VAM is widely used in the manufacturing of polyvinyl acetate emulsions, which find applications in adhesives, paints, coatings, and textiles. The copolymerization of VAM with other monomers, such as ethylene, creates ethylene-vinyl acetate (EVA) copolymers, which have excellent flexibility, adhesion properties, and low-temperature resistance. EVA is extensively used in various industries, including footwear, packaging, wire and cable insulation, and solar cell encapsulation, among others.   The versatility of VAM as a building block for different polymers and copolymers makes it a crucial material in the chemical industry. Its unique properties, such as good adhesion, film-forming capability, and chemical resistance, contribute to the wide range of applications it offers.   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.

  • Is Polyvinyl Alcohol a form of plastic?
    Jan 03, 2020
    Polyvinyl alcohol (PVA) is technically considered a synthetic polymer rather than a plastic. While both plastics and PVA are derived from polymers, they have some differences in their properties and manufacturing processes.   Plastics are typically made from long chains of polymers that can be molded and shaped when heated. They often possess a range of mechanical properties, including flexibility, durability, and resistance to chemicals. Plastics are commonly used in various applications, such as packaging, construction, and consumer goods.   On the other hand, PVA is a water-soluble synthetic polymer derived from the polymerization of vinyl acetate. It is not as thermally stable or mechanically robust as most conventional plastics. PVA has unique properties, including excellent film-forming ability, adhesion, and biodegradability, which make it suitable for applications such as coatings, adhesives, and as a water-soluble packaging material in some cases.   While PVA and plastics both fall under the broader category of polymers, they have different characteristics and applications, with PVA being distinguished by its water solubility and specific properties.   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.
