Hydrotalcite Key Benefits

Significantly enhances heat stability

Unparalleled PVC and CPVC
co-stabilizers

Exceptional acid scavenging properties
ALCAMIZER™ and MAGCELER™
Non-Heavy Metal Heat Stabilization and Co-Stabilizers
ALCAMIZER™ and MAGCELER™ represent our line of hydrotalcite products, which are not only key components of heavy metal-free stabilizer systems but also function as co-stabilizers for halogenated polymers, especially in PVC and CPVC applications.
With decades of research of thermal stabilization, excellent dispersion and performance, ALCAMIZER™ is the market standard for vinyl chloride applications.
Polyethylene Resin
Polyethylene resin is one of the most widely used thermoplastics in industrial manufacturing, valued for its versatility, chemical resistance, and durability. It serves as the base material for countless products, from packaging films and containers to automotive components and piping systems. However, during high-temperature processing, polyethylene can degrade or lose desired properties without proper stabilization.
Our Kisuma’s products ALCAMIZER™ and DHT-4 are magnesium hydroxide and hydrotalcite-based additives, play a critical role in enhancing the stability and performance of polyethylene resins. These additives act as acid scavengers, flame retardants, and heat stabilizers, helping manufacturers maintain consistent product quality, improve process efficiency, and meet regulatory requirements for safety and sustainability.
PVC Stabilizers
We produce a variety of hydrotalcite products specifically designed to provide optimal heat stability in PVC applications that enhance performance and longevity. These PVC stabilizers are already being used to stabilize high-heat cables, coated wires, pipes, and a variety of other PVC-manufactured products, contributing to a safer and more sustainable future for PVC. When combined with Ca/Zn stabilizer systems, hydrotalcite-based products create an environmentally friendly, non-toxic, and heavy metal-free alternative for PVC stabilization. This combination ensures excellent heat stability, prevents degradation during processing, and enhances the overall durability of PVC materials by preventing the release of harmful acids.
These benefits make hydrotalcite-based stabilizers an ideal choice for industries seeking sustainable and long-lasting PVC solutions.
