Wood Treating Chemicals from KMG

KMG is the sole supplier of EPA-registered pentachlorophenol (penta) in North America. Penta has played a critical role in the development of the nation’s communications and electric distribution infrastructure. For approximately 60 years, penta has been used by power generation and telecommunications companies to protect their utility poles.


KMG ‘s penta products include penta blocks and penta solutions. At our facility in Matamoros, Mexico, we manufacture solid penta blocks or make it into a liquid solution of penta concentrate. We also make penta concentrate at our formulation facility in Tuscaloosa, Alabama.

Why choose Penta from KMG-Bernuth?

  • Highly effective against insect damage and weather decay
  • 60-plus year track record of environmental safety
  • Environmentally-friendly option relative to steel poles, which consume eight times more fossil fuel in the manufacturing process than wooden poles, according to the Swiss Federal Laboratories for Materials Testing and Research.
