|Title:||Conducting polymeric products from metal powder-filled castor oil-based polyurethanes|
Chauhan, R C
|Abstract:||In the present studies, the polyurethanes were prepared by reaction between low cost vegetable oil, i.e., castor oil and its polyols and toluene 2,4-di-isocyanate. The fine metal powders, i.e., aluminum and graphite of 200 mesh size were dispersed in the castor oil and its based polyols before preparation of polyurethane pre-polymer. The pre-polymers of polyurethanes achieved by these methods were reacted by vinyl monomer followed by in-situ polymerization technique. Powder filled composites were prepared by compression molding technique. The composite specimens prepared by these methods were characterized for volume resistivity and surface resistivity to find out electrical conductivity. The products are expected to find suitable application as floor-tiles in the areas, where electrostatic charges are of great concern; conducting coatings, adhesives for electrical industries and junction boxes, panels particularly in the areas of EMI and RFI concerned.|
