Polyvinyl Acetate

Polyvinyl acetate (PVAC), also known as polyvinyl acetate. It is a polymer of vinyl acetate (vinyl acetate) with the chemical formula (C4H6O2)n. It is a colorless viscous liquid or light yellow transparent glassy particles, soluble in solvents such as benzene, acetone and chloroform. Vinyl acetate, the raw material used in PVAc emulsion, is one of the fifty most produced chemical raw materials in the world and is also the cheapest polymer monomer.   China's vinyl acetate output ranks among the top in the world. At present, more than 80% of the domestic vinyl acetate is used in the production of vinylon and polyvinyl alcohol. At the same time, downstream products such as PVAc emulsion, polyvinyl acetal and other copolymers are derived. At present, the domestic production of PVAc emulsion is more than 1 million tons.   The application fields of PVAc emulsion are very wide: 1. Construction industry, can be used for interior wall decorative coatings, colorful coatings, etc. It is also used for cement modification to improve the tensile strength, adhesion and chemical stability of cement mortar or concrete, and to prevent cracking, etc. 2. In the building materials industry, adhesive glue can be produced, such as woodworking glue, white latex, furniture glue, super glue, etc. 3. Paper industry, can be used as adhesive, impregnating agent, rewetting adhesive, 4. Packaging printing, can be used for plastic-plastic bonding, aluminum-plastic bonding, and post-processing of printed paper products In addition, it has certain applications in textile printing and dyeing, fiberglass processing, and biomedicine.   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.

Polyvinyl alcohol (PVA) is generally considered safe for humans when used as intended. It is a water-soluble polymer derived from the hydrolysis of polyvinyl acetate (PVAc) and has various applications in industries such as adhesives, coatings, textiles, and packaging.   PVA is non-toxic and does not cause any known harm to human health. It is widely used in the food industry as a thickener, stabilizer, and film-forming agent. However, it's important to note that specific formulations and additives used in PVA products might affect their safety, so it is always recommended to follow the manufacturer's instructions and guidelines when using any PVA-based products.   As with any substance, direct ingestion or excessive inhalation of PVA powder or prolonged and repeated skin contact could potentially cause irritation or allergic reactions in some individuals. It's advisable to handle PVA materials with care, follow good hygiene practices, and use appropriate personal protective equipment when necessary. If you have any specific concerns or questions about a particular PVA product or its safety, it's best to consult the PVA manufacturer or seek advice from relevant regulatory authorities or health professionals.
