SAFETY SIGN EXCELLENT IN LOW TEMPERATURE IMPACT RESISTANCE

摘要

PROBLEM TO BE SOLVED: To provide a polypropylene safety sign particularly a safety cone excellent in injection-moldability and low temperature impact resistance. SOLUTION: A safety cone having good moldability and largely improved low temperature impact resistance is obtained by injection-molding a mixture of 20-65 pts.wt. of an ethylene-α-olefin-nonconjugated polyenoic copolymer rubber and 5-35 pts.wt. of a polyolefinic thermoplastic elastomer to 100 pts.wt. of a polypropylene resin.
