Abstract

Green rubber wood [Hevea brasiliensis] of ca. 70 m.c. in lengths of 2. 25 m and cross-sections 75X75 and 88X88 mm was treated by vacuum/pressure (85 kPa/800 kPa) with a 6 boric acid equivalent solution. A pooled mean dry salt retention of 12. 4 kg/m3 was achieved in a commercial treatment plant
