Valve gasket for aerosol distributors for fluid products, e.g. pharmaceuticals, comprises ethylene-propylene or ethylene-propylene-diene copolymer rubber containing a quartz-kaolinite filler

摘要

A valve gasket for aerosol distributors for fluid products which is based on ethylene-propylene (EP) and/or ethylene-propylene-diene (EPDM) copolymer elastomer also contains a mineral filler based on quartz (SiO2) and kaolinite (Al4(OH)8Si4O10). - Independent claims are also included for - (1) a metering valve for aerosol distributors, with at least one gasket as described above - (2) a distributor for fluid products, comprising a reservoir containing a fluid product and a propellant gas, with a valve as described above, preferably a metering valve, mounted on the reservoir.
