摘要
Porous products of thermoplastic polymers and the like are formed by sintering pellets, especially micropellets and/or pellets made by rapid water quenched pelletizing of the polymers, such as by underwater pelletizing or water ring pelletizing. The pellets are of a uniform size and shape, each having approximately equal dimensions along three mutually perpendicular axes, thereby producing porous products having smooth surfaces, narrow pore size distributions, greater strength and other improved characteristics. The porous products include antiperspirant and deodorant applicator heads, wastewater treatment bubblers and selective filters.
