Description:
Polyvinyl chloride homopolymer PSM-31 is produced by the microsuspension polymerisation method. It is readily converted into low-viscosity plastisols with an excellent shelf life. PSM-31 pastes have a pseudoplastic rheology at low shear rates and have a dilatants rheology at medium or high shear rates.
Properties:
– Medium degree of polymerization
– Low viscosity and good shelf life
– Be easy deaeration
– Good foam-forming properties
