Abstract
This research aimed to analyze the effects of coating plastic thickness, pressing temperature and time on mechanical, and thermal properties of particleboard using tapioca starch as binder. The particleboard used in experiment for coating the plastic sheet was formed with a hot compression machine. According to the results, the particleboard coated with plastic sheet 0.4 mm gave higher modulus of rupture (MOR), modulus of elasticity (MOE), tensile strength (TS), tensile modulus (TM), hardness and thermal conductivity than coated with plastic 0.2 mm. Furthermore, when the particleboard was coated with pressing temperature 180 oC, an increment of pressing time in range of 5-10 min increased MOR, MOE, TS, TM, and hardness of the particleboard. Likewise, the particleboard showed an increase of MOR, MOE, TS, TM, hardness and thermal conductivity when increasing the pressing temperature from 180 to 200 oC and using the pressing time for 5 min. This is because the plastic sheet is more molten causing more penetration into the particleboard surface.
