PVA 088-60

I. Definition of Carboxylated Polyvinyl Alcohol (CPVA)Carboxylated polyvinyl alcohol（CPVA) is a hydrogen-modified polymer obtained through a carboxylation reaction based on polyvinyl alcohol (PVA，PVA 088-60 & PVA 2688). CPVA  has typically higher solubility and better performance than unmodified PVA.     II. Functions of Carboxylated Polyvinyl Alcohol PlasticizerCPVA can be used as a plasticizer to improve the processing properties and flexibility of plastics. It is often used in the production of soft plastics, coatings, and rubber products. AdhesiveCPVA can act as an adhesive, forming strong bonds between different materials. For example, when used as glue, it can bond materials such as paper, wood, and plastic together. LubricantCPVA can function as a lubricant, reducing friction on contact surfaces and extending the lifespan of materials. It is commonly used in industrial applications such as metalworking, textile manufacturing, and plastic processing. III. Applications of Carboxylated Polyvinyl Alcohol Packaging MaterialsCPVA is used in manufacturing food packaging materials, such as wrapping paper, plastic films, and straws. This polymer is not only safe and environmentally friendly but also provides excellent flexibility and water resistance, offering effective protection for food packaging. Paper CoatingCPVA is used to coat paper, enhancing its strength and water resistance. It is commonly applied in the production of books, magazines, and other paper-based products. Medical FieldCPVA is used to manufacture medical products, such as sutures and artificial cartilage. It has good biocompatibility and poses no adverse effects when in contact with human tissues, ensuring the safety and reliability of medical materials.   ConclusionCarboxylated polyvinyl alcohol is a multifunctional material with applications as a plasticizer, adhesive, and lubricant. It is widely used in packaging materials, paper coatings, and the medical field.   Website: www.elephchem.com Whatsapp: (+)86 13851435272 E-mail: admin@elephchem.com  

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.
