Abstract

In conventional method of coagulation acetic acid or formic acid is used. A novel method is reported in which yeast is used for the coagulation. Short Caryota fibres of 10mm size were used for making composites of natural rubber (NR) and samples were prepared by two methods. In the first method fibres were added at the dry stage while compounding and in the second method fibres were added directly to the latex and cure characteristics and mechanical properties were studied. Tensile modulus@300% elongation, tear strength and abrasion resistance were found to be better in latex stage processing.
