DHT-4A™ -2

DHT-4A™ -2 by Kisuma Chemicals (Kyowa Chemical Industry) is an acid scavengers based on Mg-Al hydrotalcite. It can adsorb acids based on anion exchange. It is recommended for polymers. It is a coated and dehydrated grade for high heat stability. It enhances the heat, fluid and ageing 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-4A™ -2 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.
