Studis on Plastic Materials Based on Several Cereals

Abstract

In order to utilize surplus cereals and to prevent enviromental pollution, plastic matereals based on several cereals were developed. Properties of those materials were as follows. (1) As for compression strength, plastics made from rice had the strength of 840kg/cmcm² on an average, and those made from wheat flour had the strength of 420-710kg/cmcm². These strength were increased by adding casein. (2) These materials were collapsed by water and sulphuric acid, and were soluble in caustic soda solution. However, they were not soluble in several organic solvents. (3) Specific weights were 1.3-1.4.
