A new organic biocide is said to significantly increase the lifespan of wood/plastic composites (WPCs), by dramatically reducing discoloration by mold or fungi. Preventol MPT 11 from Lanxess Corp., Pittsburgh, is an additive system tailored for WPC that is effective at levels of only 0.1% to 0.4%, vs. 5% for commonly used zinc borate. According to the company, Preventol MPT 11 can simply be added at the extruder with other additives and pigments. (800) LANXESS • www.lanxess.com
