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.
