| abstract |
The invention provides a foaming composition and a foamed body thereof. Based on the total weight of the foaming composition, the foaming composition comprises: 5wt% to 70wt% of recycled polyvinyl butyral; 10wt% to 70wt% of Polyethylene-ester type copolymer; 0.5wt% to 3.5wt% of foaming agent; 0.5wt% to 3wt% of peroxide crosslinking agent; and 0.1wt% to 2.5wt% of hydrazide type crosslinking agent. The foam molded from the foaming composition not only does not emit the unpleasant smell produced by aldehydes, but also has good mechanical properties and good deformation recovery ability. |
