Quality in every compound, testing in every plant

With every compound you receive from Preferred, consistent quality is our highest priority. Of every 1,000 compounds we deliver, on average five or fewer are returned. Preferred has production compound testing laboratories in all facilities.

Our chemists average more than 20 years in the rubber industry. Compound research and development laboratories in Barberton, Ohio, and Tallapoosa, Georgia, serve all locations and customers.

Your support from Preferred doesn’t end at delivery. Our technical and manufacturing staff are available for reformulations, trial batches and manufacturability improvements to support your successful use of Preferred compounds. This includes coming to your site on request and working in concert with your technical and production staffs.
