SD Polymers Information

Sustainable Custom-Blended Polymer for Roofing, Extrusion and Injection Molding. As a family business backed by more than 50 years of multi-generational polymer experience, we've helped manufacturers around the world divert millions of pounds of their waste streams from landfills and recycle them for further use. As pioneers in ModBit roofing, we now also apply our expertise to a multitude of other industries that rely on custom recycled polymer. We specialize in 100% IPP (isotactic polypropylene) composed of a blend of different molecular weights. We offer it as both a single-polymer IPP solution and in a blend with other polymers. As an affordable alternative to other polymers, IPP can save you money by replacing up to 40% of the costlier APP, APAO or copolymer in your current blend. It can also enhance your polymer performance. Used as a single-polymer solution or in an APP blend, our IPP compound offers: Low-to-medium viscosity Good cold-temperature resistance Higher softening point Greater puncture resistance Greater tear resistance What we do: Post-industrial and post-consumer plastic and rubber recycling Closed-loop and open-loop recycling Custom solutions Industries we serve: Commercial rolled roofing Plastic extrusion and injection molding Industrial rubber waste — buying, selling and recycling Our promise to you: We won't sell you anything unless it's good for your business AND the planet.
