产品详细说明
Product: POLYVINYL ALCOHOL
Chemical Formula: [-CH2-CH(OH)-]n,
Cas No: 9002-89-5
Properties: PVA is a high molecular polymer with a secondary hydroxyl group. The secondary hydroxyl group in the formula of PVA has high activity and can carry out typical chemical reactions similar to low molecular alcohols, such as esterification, etherification, acetalization, etc., and also react with many inorganic compounds and organic compounds. Non-toxic to humans and animals, naturally degradable, known as green products.
Applications: Mainly used in Textile sizing material, bond, coating, emulsifier, soil modifying agent,etc.
Packaging: In Paper bag of 25 kg net or 800 kgs big bag on pallets net each.
