The use of polytetrafluoroethylene micropowders having a particle size of generally less than about 20 microns as an additive for polyvinyl chloride or polyolefin unexpectedly produces compositions which are melt processable. Other unexpected properties include that the micropowder is deformable under shear and acts as a flame retardant.

The invention relates to a variable cross-section standing wave ultrasonic reactor which relates to a device for processing a liquid by utilizing an ultrasonic cavitation effect. The variable cross-section standing wave ultrasonic reactor comprises a box body, at least one ultrasonic transducer (10) and an ultrasonic transducer driving circuit, wherein the box body is used for containing the processed liquid. The cross-sectional area of a standing wave sound field in the box body periodically changes along with the position of a cross section, and the cross section of the sound field is minimum at the position (a sound pressure nodal surface) where a sound pressure amplitude is zero; the cross section of the sound field is maximum at the position (a sound pressure antinodal surface) where the sound pressure amplitude is maximum; and the cross section of the sound field is linearly or nonlinearly transited from the minimum to the maximum between the adjacent sound pressure nodal and antinodal surfaces. The volume of the liquid near the sound pressure antinodal surface is increased and the volume of the liquid near the sound pressure nodal surface is decreased to improve the utilization ratio of the sound field energy of the ultrasonic reactor.
