<p>PROBLEM TO BE SOLVED: To improve qualities such as stress crack resistance, impact resistance, etc., of molded products made of a recycled polyethylene resin or a recycled polyethylene terephthalate resin as a recycled resin. SOLUTION: In producing a molded article using a recycled resin, a recycled polyethylene resin is employed as a recycled resin and not only a polypropylene resin is employed to improve stress crack resistance properties but also an olefinic elastomer is employed to improve compatibility of the recycled polyethylene resin with the polypropylene resin. And is employed a recycled polyethylene terephthalate resin as a recycled resin together with a polybutylene terephthalate resin as an impact resistance improver.</p> |
