Abstract
A steam-sterilizable aerosol valve has a valve body of polymeric material such as polyphenylene sulfone (PPSU) having an HDT (heat deflection temperature) at 1.8 MPa stress in the range of 200-275° C. Such a valve has the ability to survive steam sterilization without significant degradation of properties or appearance.
