Abstract

Elastomeric blends based on Nitrile (NBR) and Styrene butadiene rubber (SBR) are compatibilized by 6% Chlorinated polyethylene (CPE) and further reinforced with Halloysite nanotubes in various % loading (1%, 2%, 3% & 4%) in a two roll mill mixer for preparation of nanocomposites with enhanced properties. Further to enhance the effect of nanofillers and to increase the interaction of nanofiller with rubber matrix, HNT’s were functionalized by 30% H₂SO₄ by adopting the modification process. Tensile strength, elongation at break, modulas of elasticity, tear strength, hardness & thermal stability was studied. The result revealed that the blends reinforced with 3% modified HNT’s showed better results as compared to blends with unmodified HNT’s.
