DHT™ -4V

DHT™ -4V by Kisuma Chemicals (Kyowa Chemical Industry) acts as an acid scavenger in polymer production and processing. It has surface treated with RSPO certified vegetable-based agent. It can deactivate the residual quantities of acidic substances associated with ziegler-natta, friedel craft, metallocene or other acid catalysts used to produce polymers or elastomers. It can be used at low dosage levels which ensures polymer physical- and optical properties are unaffected.

• It offers mechanism of adsorbing acids based on anion-exchange.
• DHT™ -4V is recommended for production and processing of polyolefin.
• It meets with FDA regulations and EU 10/2011 (plastic materials and articles intended to come in contact with foodstuffs).
• 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™ -4V 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.
