Abstract: PURPOSE:To obtain the title foam which is excellent in a capability of absorbing impact and is light and inexpensive, by expanding a polymer component comprising an ethylene/vinyl acetate copolymer, syndiotactic 1,2-polybutadiene and a specified high-loss factor material. CONSTITUTION:A polymer component is obtained by mixing 30-80wt.% ethylene/vinyl acetate copolymer (A) of a vinyl acetate content

Abstract: PURPOSE:To obtain the elasticity approximate to the elasticity of natural lawn simply by laying the floor material on concrete by laminating a surface material on a base layer consisting of a foamed material having specific repulsive elasticity, density and hardness. CONSTITUTION:The foamed body to constitute the base layer to be laminated with the surface material thereon is made of the foamed material having density and . The impact absorbing performance and strength are insufficient if the density is below 0.1g/cm . The impact absorbing performance is insufficient if the hardness by the SRIS exceeds 50 deg.. The thickness of the base layer is preferably >=2mm and above all, 10 to 20mm. A non-woven fabric, etc., are used in addition to the surface material of the artificial lawn, etc., as the surface material. The surface material may be simply superposed on the base layer or may be adhered by an adhesive agent or pinned thereto.
