PVA glue is the abbreviation of Polyvinyl acetate. The appearance is white powder. It is a kind of water-soluble polymer with a wide range of uses. Its performance is between plastic and rubber. Its uses can be divided into two major uses: fiber and non-fiber. Because PVA has unique strong adhesion, film flexibility, smoothness, oil resistance, solvent resistance, protective colloid, gas barrier, abrasion resistance and water resistance with special treatment, it is not only used as a fiber raw material , It is also widely used in the production of coatings, adhesives, paper processing agents, emulsifiers, dispersants, films and other products, with applications covering textiles, food, medicine, construction, wood processing, papermaking, printing, agriculture, steel, Polymer chemical industry and other industries.
Compared with similar adhesives on the market, it does not contain toxic ingredients such as formaldehyde (using modified urea-formaldehyde resin or melamine resin or water-soluble phenolic resin that can reach environmental protection E2 or higher. After adding curing agent and gypsum, it can be further Reduce the free formaldehyde content of the product), no pollution to the production and use environment, low cost, simple process, good bonding effect, fast drying and solidification speed. It is used for wood-based panel production without hot pressing and has significant advantages in energy saving.
Many customers now use PVA white latex to make slimes. This is also one of the great uses of PVA glue. In some countries in Europe and America, many people give their children the finished slime as an elementary education. Its material is non-toxic and environmentally friendly, so there is no need to worry about whether the glue will harm children.
