PVA 2688

Polyvinyl alcohol 2688 is a polymer compound with the formula (C2H40)n, where the value of n is greater than or equal to 1000. It is a polymer in chemical structure, its molecular weight is very high, and it has very special physical and chemical properties. The most important thing about the properties of PVA 2688 is its viscosity. Viscosity is a basic property of liquid fluidity and describes the degree of viscosity of a liquid. The viscosity of PVA 2688 is often used to describe its viscosity in aqueous solutions, and its value is generally measured at 20 ° C.    PVA 2688 has a viscosity of up to 50(mPa.s), which makes it a very viscous polymer compound. Due to its high molecular weight, the interaction between molecular chains is very strong, so the molecular chain of PVA 2688 is difficult to flow, and its viscosity is high. At the same time, because the polyvinyl alcohol 2688 molecule contains a large number of hydroxyl (-OH) groups, these groups can form hydrogen bonds with water molecules, so that it has good solubility in water.   The viscosity of PVA 2688 directly affects its performance in practical applications, so it is usually necessary to select an appropriate viscosity range. According to the actual process and needs, different viscosities of polyvinyl alcohol 2688 can be selected for application. The high viscosity of PVA 2688 makes it widely used in industrial and agricultural fields. For example, it is used in the manufacture of textiles, paper, paint adhesives and other products. In addition, it can also be used for the preparation of certain pharmaceuticals, daily chemical supplies and so on. Due to its good solubility in water, it is also used as a precipitator, dispersant, lubricant, etc., and PVA 2688 has a wide range of application prospects.   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.
