Abstract: | ?Addition of certain sorts of calcium carbonate fillers greatly improved mechanical and rheological properties of resulted silicone-modified polyurethane(SPU) sealants.Effects of filler quantity,particle size,and blended ratio on tensile strength,elongation,hardness etc.and rheological properties of obtained SPU sealants were studied,which were basic behavior criterion in practical use. |
