Title: The Innovations of Minerva Piffarerio: A Pioneer in Toner Technology

Introduction

Minerva Piffarerio, an accomplished inventor based in Erie, Colorado, has made significant contributions to the field of toner technology. With a total of two patents to her name, Piffarerio's work has been instrumental in advancing the efficiency and effectiveness of toner production processes.

Latest Patents

Piffarerio's latest patents include groundbreaking methods for closed air circulation toner rounding. This innovative approach involves vigorously mixing less than about 5 percent by weight of particulate silica with the total weight of a starting toner in a closed, recirculating air system. The starting toner comprises at least about 4.5 percent by weight of a wax and a minimum of 5 percent by weight of a softening agent. Importantly, the mixing temperature is controlled to remain no more than 13 degrees Celsius above the onset of the glass transition temperature of the starting toner. The result is a high-quality final toner comprising rounded toner particles embedded with particulate silica. Additionally, Piffarerio has developed toner particulates that consist of a first resin made from a cross-linked copolymer, a second resin from a non-cross-linked copolymer, and a wax containing an ethylene propylene copolymer. These innovations signify a leap forward in toner production, enhancing both quality and performance.
