Company Story

Tom Rosenmayer founded Silpara Technologies in 2019 to overcome the barriers to performance in natural rubber products. In 2020, Brian O’Connell was brought aboard to help commercialize Silpara’s radical new nanocomposite. This innovative nanocomposite solves the number  one pain point in optimal truck and bus tire performance: polymer-filler interactions that occur in natural rubber product formulations.
