Inovol PA4

Is a partially hydrolysed polyvinyl acetate, ready to be dispersed in water. It enhances strippability and efficiency especially with low k-value resins. This is a primary suspending agent which is efficient to optimise size control during polymerisations of PVC under demanding conditions ( high condenser action, high M/W ratio, hot water and simultaneous charging conditions). It's used to determine porosity, particle size and size distribution. And it's possible to add a secondary suspending agent.
