Thermoplastic polyolefin sheet composition having low hardness and low elongation and thermoplastic polyolefin sheet comprising same

The present invention relates to a thermoplastic polyolefin sheet composition, and more particularly, to a thermoplastic polyolefin sheet composition having low hardness and low elongation by mixing appropriate amounts of a cross-linked polyolefin resin, a non-cross-linked polyolefin resin, a polystyrene-based resin, and a high melting point polypropylene resin, and to a thermoplastic polyolefin sheet comprising the same. The thermoplastic polyolefin sheet composition includes 5 to 60 wt% of a crosslinked polyolefin resin, 5 to 30 wt% of a non-crosslinked polyolefin resin, 15 to 40 wt% of a polystyrene-based resin, and 5 to 10 wt% of a first polypropylene resin. 本发明涉及一种热塑性聚烯烃片组合物，特别是通过适当量的交联聚烯烃树脂、非交联聚烯烃树脂、聚苯乙烯基树脂和高熔点聚丙烯树脂的混合而具有低硬度和低伸长率的热塑性聚烯烃片组合物，以及包含该组合物的热塑性聚烯烃片。热塑性聚烯烃片组合物包括5-60重量％的交联聚烯烃树脂、5-30重量％的非交联聚烯烃树脂、15-40重量％的聚苯乙烯基树脂和5-10重量％的第一聚丙烯树脂。
