| Vinnolit® MP 7151 PVC for paste application. Vinnolit® MP 7151 is a fine grained PVC homopolymer with a medium emulsifier content. It yields plastisols exhibiting a very low viscosity at low/high shear rates and a Newtonian flow characteristic even at low plasticizer contents (40 - 60 phr). Plastisols with Vinnolit® MP 7151 show a very low viscous, homogeneous flow behavior and very high filler tolerance, which makes it perfectly useful for higher speed coating process, e.g. in flooring base coatings, rotary screen printing applications as well as for textile base coats. Additionally a very good pot life characteristic and good thermostability bringing added value in that fields of application. Plastisols made with Vinnolit® MP 7151 exhibit the following core properties: very low viscosities even with high solids, content formulations, good thermal stability with a wide range of standard stabilizers, especially liquid Ca/Zn or Ba/Zn types, good gelation rate, fast mixing/dispersion properties with high-speed mixers, potential to accept high filler/pigment loadings without sedimentation or aggregation, very good pot life stability, good adhesion on textile substrates. The main applications are: The production of compact vinyl wallpaper base with low coating weights, both on high speed reverse-roll coating lines and on rotary screen coating lines. The plastisols exhibiting near Newtonian flow characteristics at very high shear rate in the high solid content plastisols usually employed. Very low viscosity plastisols with high filler loading for fabric impregnation e.g. in conveyor belting carcasses, flooring and carpet tile backings. Dip coating with low viscous, low sedimenting plastisols.Information provided by Vinnolit. |
