Vinnolit® E 67 ST PVC for paste application. Vinnolit® E 67 ST is a very fine-particle, paste-making emulsion homopolymer, giving medium viscosity plastisols with a good shelf life. Plastisols made with Vinnolit E 67 ST have a slightly pseudoplastic rheology. Vinnolit® E 67 ST exhibits excellent foaming characteristics in chemically blown foams, particularly for screen printing and hot embossing for wall covering manufacturing. The product has the following properties: outstanding foaming characteristics; low density foams with fine cell structure, even at very high filler content. Medium viscosity at low shear rates with slightly pseudoplastic flow behavior. Very fine particle size. Foams with good whiteness. Good foam inhibition (e.g. with benzotriazole). Low gelling temperature. Good paste deaeratibility. The product is compatible within a wide range of processing variables, with no tendency to overfoaming.Information provided by Vinnolit. |
