Plymouth-based Minnesota Rubber and Plastics, a manufacturer of rubber and plastic-molded components, is changing ownership again. Sweden-based Trelleborg Group announced it is buying the company from New York-based private equity firm KKR & Co. LP for $950 million. The deal is expected to close by the end of the year. KKR acquired Minnesota Rubber in November 2018 from Minneapolis-based private equity firm Norwest Equity Partners.
