About Us
Triangle Rubber & Plastics is a privately owned and managed company that thoroughly meets the challenges in both the rubber and plastics industries. Founded over 70 years ago, Triangle has been managed by the owners, who believe it is best to be involved in the daily activities of the business and be located on-site. Triangle has grown over these 70 years, continually expanding into new markets and processes to serve the changing environments in the markets they serve.
