Abstract
A formamide-free foam prepared by using sodium bicarbonate as a foaming agent and electron-beam irradiation for crosslinking is revealed. After copolymer and sodium bicarbonate being mixed evenly, the mixture is heated and compounded to form an intermediate. Then the intermediate is pressed and injected to form a sheet. Next the intermediate is irradiated by an electron-beam to form crosslinks therein. At last the intermediate is heated and foamed to get a formamide-free foam. Compared with foam produced by using azodicarbonamide as the foaming agent available now, formamide-free foam not only causes no harm to human health but also gives no negative effect to the environment during recycling. Thus the formamide-free foam is really environmentally friendly.
