Elemental Chlorine Free (ECF) pulp bleaching is now the dominant pulp bleaching process in the world to reduce the environmental pollution. The possibility of producing easy bleachable pulp from rubber stem and branches by oxygen delignification was studied in this study. Delignification of rubber wood was carried out by conventional Kraft pulping under varying conditions. Kraft pulp from rubber tree was bleached by DoEpD1 (where Do represents 2% chlorine dioxide, Ep represents peroxide reinforced alkaline extraction and D1 represents 1% chlorine dioxide) sequences. Kappa number and pulp yield of both stem and branch of rubber wood were comparable to other hardwood species before oxygen delignification. Oxygen delignification reduced kappa numbers 24.51% and 23.41%) and increased brightness 21.12% and 26.5l%o in branch and stem of rubber wood pulp, respectively at 20% active alkali (AA). Branch pulp obtained brightness 77.57% and for stem 79.50%>. After oxygen delignification branch pulp showed higher bleachability than stem pulp. The Kraft controls pulp could not reach target brightness of 80% using only DoEpD1 in stem and branch pulp. But oxygen delignified Kraft pulp reached brightness 83%for branch and for stem 81.3%). Paper making properties of the bleached pulps did not show significant variation after oxygen delignification, apart from tear index in oxygen pre-bleached pulp. Considering bleachability and papermaking properties, oxygen was the best pre-bleaching option for attaining standard ISO brightness (80%)) of stem and branch of pulp. The hand sheets were made and the physical strength properties of pre-bleached and final bleached pulp likely tear, tensile and burst were evaluated at 250 and 450 CSF (Canadian Standard Freeness) freeness level. The pulps produced from stem and branches of rubber tree possessed moderate strength properties. These could be used for producing moderate quality writing, printing and wrapping papers.
