Properties Of Soy Protein Isolate-chitosan Bioadhesives For Production Of Oil Palm Trunk Particleboard

Formaldehyde-based adhesive had been used commercially in production of wood-based composite. However, since it contains carcinogenic formaldehyde that is hazardous mainly to human health, researchers all over the globe are focusing on producing formaldehyde-free adhesive from natural resources. Soy...

The particleboard with targeted density of 0.80 g/mm3 and 10% adhesive content (based on oven dry weight of oil palm trunk) were produced by mixing the oil palm trunk particles with different ratio soy protein isolate and chitosan (3:1, 2:1, 1:1, 1:2 and 1:3) before pressed with hot press machine at 180°C and 5 MPa pressure for 8 minutes.
