ABSTRACT:
A device for delivering an aerosol, comprising: a casing member, a valve stem, and a diaphragm. The diaphragm contains a blend of (a) 100 parts by weight of a polyolefin random copolymer of about 80 to about 95 mole percent ethylene and a total of about 5 to about 20 mole percent of 1-butene, and (b) at least 10 parts by weight of a rubber comprising a styrene-ethylene/butylene-styrene block copolymer based on 100 parts by weight of polyolefin. The styrene-ethylene/butylene-styrene block copolymer is substantially uniformly dispersed within the polyolefin. The blend preferably has a Shore A hardness of 65 to 85.
