Overview Modified polyvinyl alcohol (PVOH) is graded according to different degrees of polymerization, hydrolysis and copolymerization monomers. The modification of PVA is mainly to use the double bonds, ester groups and the chemical activity of the hydroxyl group after alcoholization of vinyl acetate to change the side chain group or structure, and introduce other monomers to become copolymers dominated by PVA.
Overview PVOH 725 PVC Grade is a 71 mol% hydrolyzed polyvinyl alcohol specifically developed as a primary suspending agent for suspension polymerization of vinyl chloride. It offers low molecular weight and low viscosity.
Overview PVOH 735 PVC Grade is a 73 mol% hydrolyzed polyvinyl alcohol dispersant developed specifically for suspension polymerization of vinyl chloride. It meets PVC manufacturers' requirements for better particle size control at lower addition levels than conventional 72.5% grades.
Overview PVOH 745 PVC Grade is a 74 mol% hydrolyzed polyvinyl alcohol. It has better quality and stable performance, bringing stability to customer products.
Overview PVOH 785 PVC Grade is a 78 mol% hydrolyzed polyvinyl alcohol It is specially used to adjust the particle shape of SPVC, or to make blended resins, as well as copolymers of vinyl chloride and vinyl acetate.
Overview PVOH 452 PVC Grade is a 43 mol% polyvinyl alcohol aqueous solution. Unlike conventional polyvinyl alcohol (soluble in specific alcohols but insoluble in water), it is completely soluble in water and contains very low levels of methanol.
Overview PVOH 552 PVC Grade is a 53 mol% hydrolyzed polyvinyl alcohol. Using a unique batch process, the degree of hydrolysis and particle size of the product can be more effectively controlled.
Overview PVOH 8035 PVC grade is an 80 mol% hydrolyzed polyvinyl alcohol. It has a high molecular weight and medium viscosity, allowing for effective control of particle size distribution, porosity, and bulk density in PVC resins.
Overview PVOH 8039 PVC Grade is an 80 mol% hydrolyzed and medium viscosity polyvinyl alcohol used primarily as the primary suspending agent in the production of polyvinyl chloride.
Overview PVOH 8048 PVC grade is a high viscosity polyvinyl alcohol with a degree of hydrolysis of 80%, specially developed for use as a primary suspending agent in the suspension polymerization of vinyl chloride.
