The composition and the biodegradation characteristic polyurethane foaming body in order to manufacture the biodegradation characteristic polyurethane type foaming body

摘要

It designated that the biodegradation characteristic polyurethane foaming body is manufactured as purpose, the composition and the biodegradation characteristic polyurethane foaming body in order poly- (hydroxy butyrate) poly- all of the polymer and reproducible source, includes the blend which designates isoshianeto and the additive as the base, to manufacture the biodegradation characteristic polyurethane type foaming body. In method, when poly- (hydroxy butyrate) + poly- all, isoshianeto and the additive are mixed beforehand in the blender of specification and homogeneity is achieved, the blend for increasing is filled in the die. After the hardening, the product which is obtained fluctuates with the ratio of the reagent, makes the production of some products possible, density, tough characteristic and the foaming body quality which possesses cell size are shown.
