DHT™-4a & DHT™-4V

DHT™-4 is the flagship of our branded range of synthetic hydrotalcite materials. It is the industry’s gold standard for deactivation of acidic residues in polyolefins. Through irreversible anionic exchange deactivation, DHT™-4 ensures polymers are protected and will process and perform to their full potential. Our products protect your assets from corrosion, prevent deactivation of functional additives, increase hydrolytic stability and improve organoleptic properties.

Acid Scavenger for Polyolefins

Polyolefins are utilized in a wide range of applications, including packaging, cable insulation, clothing, and medical products. However, before polyolefin materials from the reactor can be used for their intended purpose, they must undergo several processing steps. 


During these processes, elevated temperatures, shear forces, and exposure to oxygen can trigger degradation that significantly affects the polymer melt, as well as the mechanical and aesthetic properties of the final product. Choosing the right stabilizing additives is crucial in preventing these negative effects. A typical additive package for polyolefins includes primary antioxidants (phenolic), secondary antioxidants (phosphites or phosphonites), and acid scavengers. Synthetic hydrotalcite has been widely used as an acid scavenger in polyolefins, with our brand name DHT-4A being the top attentive used since the late 1970s. Our high-quality hydrotalcites, DHT-4A, can synergistically enhance the performance of other additives and pigments within the formulation.
