Liquid PVC Blending

Plastisol or paste PVC mixtures are dispersions of emulsion or emulsion/microsuspension PVC resins in plasticisers. Alternatively organosols are based on the use of a lower boiling point liquid. 

All mixers are usually enclosed and fitted with a vacuum deaeration facility, particularly necessary for transparent top coat and foam formulations. 

An excellent review of the different processing techniques can be found on the Hydro Polymers website, www.hydropolymers.com.
