DHT™ -4C

DHT™ -4C by Kisuma Chemicals (Kyowa Chemical Industry) acts as an acid scavenger. It is Mg-Al hydrotalcite that can adsorb acids based on anion-exchange. It is a hydrophilic and calcined grade for higher thermal stability (>300°C). It is used widely in all types of polymer formulations for primary or additional stabilization.

• It enhances the heat, fluid and aging resistance of chloroprene (CR) and epichlorohydrin (ECO) rubbers.
• It improves both the mechanical and the chemical resistance of rubber compounds.
• It is high-performance, PFAS-free elastomer solutions without compromising quality.
• It enables formulators and sustainability-driven material specifiers to reduce or eliminate the use of fluorinated elastomers like FKM, thus reducing the reliance on materials flagged as hazardous to human health and the environment.
• DHT™ -4C also contributes to the United Nation’s Sustainability Development Goals 12 (Responsible Consumption) and 13 (Climate Action) by improving production safety, regulatory compliance and long-term material sustainability.
