At present, the solid glue on the market is divided into PVP solid glue and PVA solid glue from the material. Because these two kinds of solid glue are different in material selection, their application range is also different, and the price is also different. Below, Xiao Bian brings the difference between solid glue pvp and pva.
The difference between solid glue pvp and pva:
PVP adhesive is a new type of environment-friendly solid adhesive, PVP (PVP = Polyvinylpyrrolidone, chemical name is polyvinylpyrrolidone, a water-soluble polymer, its monomer is N-Vinylpyrrolidone (N-vinyl-2- Pyrrolidone) is a water-soluble polymer compound with excellent performance and versatility. It is a high-tech, high-value-added fine chemical product and an important chemical intermediate and pharmaceutical intermediate advocated by the international community. As the main ingredient, it has high viscosity and no Environmental protection and other characteristics of a solid glue.
PVP adhesive features high viscosity, suitable for office paper bonding. The smoothness is good, and the smearing resistance is much lower than that of PVA glue. Safe and non-toxic, unlike the PVA solid glue, it must be added with formaldehyde. At the same time, PVP itself is a kind of non-toxic raw material, so PVP glue is non-toxic and environmentally friendly, especially suitable for children.
PVP adhesives are expensive in China, and the market is quite narrow. However, the export of solid rubber is PVP, the European and American markets, the main plastic adhesive market mainly PVP. It is believed that with the enhancement of the environmental awareness of the Chinese people, the market prospect of PVP adhesive is infinitely good and will surely replace the current PVA adhesive.
At present, the commercially available solid glue stick is basically PVA (polyvinyl alcohol) and PVP (polyvinyl pyrrolidone) as the main raw material, and its colloid is white or light yellow. The solid glue stick made of PVA has better market competitiveness due to its lower cost, and PVA solid glue is a new product in the adhesive. Its main features are: easy to get raw materials, simple production, long shelf life, easy to carry, easy to use, strong bonding, suitable for paper products bonded. It is mainly used for bonding a variety of paper and paper products and is suitable for use by office workers, accountants, clerks, teachers, students, and related personnel.
The difference between solid glue pvp and pva is mainly in material selection. PVP solid glue is non-toxic and environmentally friendly, but the price is expensive. PVA glue is low in price and easy to carry. It is widely used.
