Vinnolit® P 70 PS PVC for paste application. Vinnolit® P 70 PS is a fine grained homopolymer for plastisol processing giving medium-viscosity plastisols with an excellent shelf life. Pastes made with Vinnolit® P 70 PS show a moderate pseudoplastic rheology at low shear rates and a moderate dilatant flow behavior at higher shear rates, which becomes more pronounced at low plasticizer level. This dilatant behavior can easily be reduced by blending with Extender grades, like Vinnolit® EXT or by blending with special emulsion grades. Due to its very low emulsifier content the product shows a very low moisture absorption making it ideally suited for outdoor applications. Thin plastisols of Vinnolit® P 70 PS in combination with special emulsion resins show excellent properties for dip coating (Foulard) of e.g. textile substrates. The core properties of Vinnolit® P 70 PS are: high transparency, clear films, glossy homogeneous surface neutral, color and good thermostability, low water absorption, good weathering properties, perfect adhesion on textile substrates, good pot life and storage stability, fine particles, moderate yield point for dip coating, high bath stability of thin plastisols.Information provided by Vinnolit. |
