制膏用聚氯乙烯Vinnolit® E 67 FF是一种细颗粒、低中分子量乳液型聚氯乙烯均聚物,乳化剂含量中等。它生产的塑性溶胶在低剪切率和高剪切率下具有中等粘度,基本上具有牛顿流动特性,增塑剂含量低(40-60 phr)。它特别适用于低增塑剂含量的致密或化学发泡配方。它通常表现出良好的凝胶化/熔融速率,并具有良好的热/光稳定性和广泛的稳定剂。建议使用高速型搅拌机。加工和应用:Vinnolit® E 67 FF生产的增塑剂含量低的塑性溶胶非常适合使用“刚果”工艺对缓冲地板和墙面覆盖物的化学发泡泡沫进行扩散涂层,在高和低的E值下都可以获得非常细的封闭细胞结构,具有良好的抑制作用和轮廓清晰度。扩展级别。塑料溶胶可采用反向辊涂、旋转筛涂。 PVC for paste making ® Vinnolit E 67 FF is a fine particle size, low- medium molecular weight emulsion type PVC homopolymer with a medium emulsifier content. It produces plastisols exhibiting medium viscosity at low and high shear rates with essentially Newtonian flow properties with low plasticizer levels (40-60 phr). It has been particularly developed for low plasticizer content compact or chemically foamed formulations. It exhibits generally excellent gelation/fusion rates and gives good thermal/light stability with a wide range of stabilisers. The use of high speed type mixers is recommended. Processing and Application: Vinnolit E 67 FF produces plastisols with low plasticizer content which are ideal for the spread coating of chemically blown foams for cushioned flooring and wallcoverings using the "Congoleum" process, where a very fine closed cell structure with excellent inhibition and contour sharpness may be achieved at both high and low expansion levels. Plastisols can be applied by reverse-roll coaters, rotary screen coaters. |
