PVA Celvol 325

PVA1799H, with its distinctive white flocculent appearance, stands out from conventional granular PVA. Flocculent polyvinyl alcohol is prepared by the composite of polyvinyl alcohol and other substances. It has a rod-like and helical structure, which makes it different in properties ‌.   Flocculent polyvinyl alcohol 1799H has higher crystallinity, higher blocking distribution of residual acetic acid, lower surface tension of aqueous solution than granular polyvinyl alcohol, and better colloidal protection than flake polyvinyl alcohol. In addition, flocculent PVA has a lower density than flake PVA, which makes it easier to handle in certain conditions where mixing facilities are not perfect.   This unique variant of PVA offers a wide range of applications and brings several advantages to different industries. In the printing and dyeing industry, it is mainly used for viscosification, thickening and sizing; In the paper industry, it can increase the viscosity of the slurry and form a protective film during the drying process to prevent the powder from falling off during the pulping process. In the food industry, flocculent polyvinyl alcohol is commonly used as a preservative. In addition, in the construction industry, flocculent polyvinyl alcohol has a high temperature viscosity, suitable for grouting operations, and can be used as a modified material of asphalt, with good permeability resistance ‌. PVA, including specialized variants like PVA1799H and PVA100-27H, holds great potential in the global market due to its unique characteristics and eco-friendly nature. As industries increasingly adopt sustainable practices, the demand for PVA as an alternative to traditional materials continues to rise.   The global market for PVA is experiencing steady growth, driven by factors such as increasing environmental consciousness, stringent regulations on packaging waste, and the need for biodegradable materials. PVA, being a renewable resource with excellent water solubility and biodegradability, offers a promising solution to these challenges.   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.
