A line of affordable styrene-butadiene rubber impact modifiers derived mainly from recycled tires is newly available in pellet concentrate form. PolyDyne Concentrates from Lehigh Technologies LLC, Naples, Fla., contain PolyDyne SBR fine and ultra-fine powders (74, 106, or 180 microns) blended with appropriate carrier resins and compatibilizers. These concentrates can be added directly to extrusion or molding, the company says. Field tests indicate they work well in polyolefins, ABS, glass-reinforced nylon, PBT, TPOs, TPUs, and other TPEs. Also promising are early results with mineral-filled PP and nylon where PolyDyne appears to further boost dimensional stability while minimizing loss of impact strength. These products have also attracted interest from processors using recycled materials. PolyDyne recently acquired Germany's Microtec GmbH, a global leader in fine powderization technology. The acquisition opens new opportunities for PolyDyne, including the potential to offer near-nano-size rubber particles to enhance plastics' impact strength, elongation, and abrasion resistance.
