FACTICE FROM OIL OF PUTRANJIVA-ROXBURGHII

Preparation and characterization of factice by vulcanization of oil ex tracted from Putranjiva roxburghii, a fairly abundant plant of the tro pical Indian subcontinent, is presented. This information serves as a processing aid for substituting commercially available factices. Mecha nical and thermal studies of this new type of factice, blended with ru bber, showed higher thermal stability and improved processing characte ristics during extrusion and calendering operations compared to rubber without factice.
