Kuraray Poval™ LM grades have especially low saponification and are available as with an extremely low degree of hydrolysis of between 33 and 53 mol%. This unique combination makes these PVOH polymers excellent as secondary protective colloids in suspension polymerization of PVC. A high acetate content gives these polyvinyl alcohols a low glass transition temperature, so they can be dispersed in cold water or dissolved in formulations with organic solvents.
PVC producers use Kuraray Poval™ LM grades to significantly improve the quality of their products. These PVA polymers enable precise control of grain formation in polymerization to optimize structure, morphology and particle size distribution. Kuraray Poval™ LM grades are completely free of organic solvents. Moreover, the monomers are easy to remove, so they help improve the efficiency of production processes. For use as a primarily dispersing agent, Kuraray offers PVC producers Kuraray Poval™ L grades.
Use the advantages of Kuraray Poval™ LM grades for your PVC applications – and benefit from the expertise of Kuraray, a world-leading PVOH producer.
