The objective of polymer blending is a practical one of achieving commercially viable product through either unique properties or lower cost than some other means might provide. The current study proposes the reparation of structural foams based on PLA/PP and PLA/HDPE polymer blends with chemical blowing agent were studied. Various ratios of base polymers were prepared and analyzed. The properties like density, hardness, tensile properties, impact properties, flexural properties, opacity, water absorption, acid resistance, base resistance, flame resistance and heat resistance are studied. The samples were also evaluated for FTIR studies and DSC. The optical images of the samples were examined. The properties of the foams were compared with the standard sheet without using blowing agent.
