Abstract: The present invention relates to an airbag housing cover containing a thermoplastic elastomer composition which contains the following components (A) and (B) and contains from 10 to 300 parts by weight of the component (B) per 100 parts by weight of the component (A) and in which the melt flow rate at a measurement temperature of 230° C. and a measurement load of 21.18 N is from 5 to 50 g/10 min: Component (A): a polypropylene-based resin Component (B): an olefin-based block copolymer containing a polymer block composed of ethylene and an ethylene ?-olefin copolymer block.
Abstract: The invention relates to unique applications for the novel high melt flow, low viscosity, selectively hydrogenated styrene-butadiene-styrene (hSBS) or selectively hydrogenated controlled distribution styrene-butadiene/styrene-styrene (hSBSS) block copolymers, wherein the melt flow rate of said block copolymer is at least 100 g/10 min at 230° C. under 2.16 kg mass according to ASTM D1238. These block copolymers are novel and have the highest melt flow rate of any styrenic block copolymer also possessing high strength and elasticity. It has applications that prior to the present invention were not normally possible due to the normal low melt flow rate of styrenic block copolymers. The present invention also encompasses various fields of use such as a fiberglass hSBS or hSBSS reinforced mat, low viscosity hSBS or hSBSS coatings for industrial uses, hot melt adhesives prepared from hSBS or hSBSS blended with polyalpha-olefins, and elastic film, fiber, and nonwoven constructions using hSBS or hSBSS.
