The glycerin transformation process employed by LEUNA-Harze GmbH is not only designed for efficiency and sustainability but is also integral to the production of chlorine, hydrogen, hydrochloric acid, and sodium hydroxide. This comprehensive method seamlessly combines electrolysis with internal epichlorohydrin (ECH) synthesis, effectively converting bio-based glycerin in a more eco-conscious manner. Harnessing steam energy and utilizing sodium chloride and waste materials, this approach yields vital components necessary for various products, particularly bio-based epoxy resins and reactive diluents.

  1. Bio-based production
    Utilizing bio-based Epichlorohydrin for Epilox® products effectively curtails CO2 emissions in the manufacturing process. This eco-friendly method aligns with our dedication to sustainable practices.
  2. Optimized technology
    Optimized technology and efficient manufacturing practices are integral to lowering overall CO2 emissions associated with traditional Epilox® products. This commitment to optimization underscores our ongoing efforts to enhance process eco-friendliness.
  3. Renewable energy integration
    Incorporating sustainable energy sources in the production process to further reduce the amount of CO2 emitted, demonstrating a commitment to environmental responsibility.

Bio-based Epoxy Resins and Reactive Diluents

A closer look at the bio-based epoxy resins and reactive diluents

The Epilox® A & F series stands out with its bio-based carbon content in Bisphenol A and Bisphenol F resins, ideal for a wide range of industrial applications. These resins also exhibit exceptional crystallization resistance.

The Epilox® P series offers specialized bio-based reactive diluents tailored to meet diverse industrial requirements.

The Epilox® T19 series takes it a step further, combining the strengths of A resin (Epilox A19-00G) and F resin (Epilox F17-00G). The T19 series introduces variations in viscosity, providing users with a broader spectrum of options to suit specific application needs.

These series are more than just products; they represent our dedication to innovation, quality, and environmental stewardship in the industrial sector.
