    Abstract: A supercharger system for a vehicle engine comprises a supercharger and a sound isolation unit at least partly surrounding the supercharger. The sound isolation unit comprises an inner layer facing the supercharger, a sound barrier layer facing away from the supercharger and a core there between. All three layers are made from polyurethane but with different densities. Furthermore, the core comprises an open cell structure for sound absorption.

    Abstract: A resin composition for injection molding comprising (I) 70-90 wt. parts of a propylene polymer resin having a MFR of at least 30 g/10 min. but smaller than 200 g/10 min. as measured at 230° C. according to ASTM D-1238, (II) 5-25 wt. parts of an ethylene-α-olefin copolymer having a melt strength (MS160) of larger than 50 mN but not larger than 300 mN as measured at 160° C., and (III) 5-25 wt. parts of an olefin polymer resin having a density of at least 850 kg/m3 but not larger than 930 kg/m3 as measured according to JIS K6760, and a melt strength (MS160) of smaller than 30 mN as measured at 160° C., wherein the sum of (I), (II) and (III) is 100 wt. parts. This resin composition gives an injection molded article exhibiting enhanced impact strength at a low temperature and having no or minimized flow marks on the surface thereof.
