R. Srilathakutty et al., Coir pith as low cost filler in microcellular soles based on natural rubber-high styrene resin, PLAS RUB C, 29(2), 2000, pp. 96-99
The utilisation of coir pith (modified and unmodified) as filler in microce
llular soles based on natural rubber-high styrene resin blends is presented
. The cure characteristics and technical properties of microcellular soles
have been evaluated. Coir pith can be used as a filler in amounts up to 50
phr without much reduction in properties. Optical micrographs of razor cut
samples of microcellular sheets are presented; the sheets with modified coi
r pith show a more uniform cell structure.
