(57) Abstract: An ethylene-based polymer, an isoprene-based polymer, a butadiene-based polymer, a styrene-based polymer, an α-olefin-based polymer having 3 to 12 carbon atoms, or silicone is used as a base matrix. An elastomer composition characterized by containing a crosslinked polymer particle having an average longest diameter of 30 to 600 μm obtained by crosslinking the system polymer and substantially not melting, and containing a boiling xylene-insoluble gel component; and The ten-point average roughness obtained by molding this composition is 20 μm Molded products that are above. [Effect] An olefin-based thermoplastic elastomer which is inexpensive and has excellent mechanical strength, rubber properties, durability and moldability can be produced, and this is used as a base matrix to disperse specific crosslinked polymer particles. Can form irregularities on the surface of the molded product, sliding, abrasion resistance, non-staining, Excellent dust removal (brushing effect), design, It is possible to provide a high-quality surface covering member capable of appealing the feeling, touch, and the like to human sensation. |
