520			_aRubberwood is amendable to mechanical, semichemical and chemical pulping processes to produce various grades of paper with acceptable physical and optical properties. The unbleached rubberwood sulphate pulp when blended with a certain proportion of long fibre pulp would be suitable for making wrapping paper or linearboard. The bleached pulp would be suitable for making writting and printing papers. Rubberwood pulps from both mechanical and semichemical processes are suitable for making corrugating medium and also for newsprint. Rubberwood may thus be used commercially for making pulp and paper, provided special attention is given to remove the residual latex in the pulp which otherwise will impair the quality of the paper produced. In this respect several measures have to be undertaken, such as seasoning the logs for at least a month before debarking and chipping, and then if necessary, treating the pulp with surfactants to remove the latex. In this way, rubberwood would be as good as many other temperate hard woods for the production of pulp and paper.
