Bamboo offers cost-effective component in panel form is well suited to wood substitute can be used as furniture components. In the present study, borak (Bambusa balcooa ) bamboo were used for manufacturing bamboo panel. Mitinga (B. tulda) bamboo were used for making mat and rubber wood veneers were used for manufacturing mat overlaid veneer board. Borax-boric acid (BB) treatments were given to enhance the durability of mat, strips and veneer. The treatments were carried out using borax-boric acid (1:1) aqueous solution of different concentrations at different time schedule by soaking process. The optimum retention of preservative chemicals through mat, strips and veneer were determined. Using 5% BB solution, the average retention was found 21.90 kg/m3 in A (1.22 m X 0.91m) size mat and 24.39 kg/m3 in the B (0.61 m X 0.91m) size mat after 3 days soaking. Using 7% solution, retention of 25.17 kg/m3 A size mat and 28.44 kg/m3 were obtained in B size mat after 3 days treatment. In the case of bamboo strips, highest retention of 26.22 Kg/m3 was found when treated with 7% solution for 3 days. Highest retention 24.53 kg/m3 was obtained in 7% BB treated rubber wood veneers after 3 days soaking. Average retention of 22.07 kg/m3 was found when veneers were treated with 5% BB solution for 3 days. It was observed that, veneers were treated with 7% BB solution attained average retention of 19.20 to 24.53 kg/m3 after 1 to 3 days treatment. It was found that the retention were gradually increased with increasing concentration and time period. After preservative treatment, the materials were used in making composite products for chair.
