Abstract
PURPOSE: Pulp wastes and/or wood fibers are mixed with a foaming vinyl chloride resin composition and the mixture is foamed with heating to produce title foam suitably used as construction and packaging materials because of its moderate stiffness, high restoration force and cushoning properties.
CONSTITUTION: (A) 100 parts by wt of a foaming vinyl chloride resin are mixed with (B) 10W400 parts, preferably 25W300 parts, of pulp wastes and/or wood fibers, preferably with a length of 1W3 mm and a specific gravity of 0.02W0.05. The composition is foamed under heating to produce the objective foam. When component B is employed, they are first made into granules or flakes and soaked in water, then dried to adjust the water content to 30W100 wt%.
