Controlled Composition and Rigorous Quality Control with Alcamizer

The exceptional performance characteristics of ALCAMIZER are intricately tied to its chemical composition. Therefore, meticulous control over the content of magnesium (Mg), aluminum (Al), and zinc (Zn), alongside precise crystallization and the elimination of residual impurities, holds paramount importance in upholding unwavering quality standards. Employing automated production methods, we subject ALCAMIZER to rigorous oversight through our comprehensive quality control system. This diligent approach ensures that your products consistently exhibit elevated heat stability and remarkable transparency. Furthermore, our commitment to ensuring an uninterrupted supply is evident as we maintain ample ALCAMIZER stock, assuring our global clientele of seamless continuity and unwavering reliability.

Innovative PVC/CPVC Stabilization Mechanism

ALCAMIZER exerts its remarkable stabilizing prowess within PVC/CPVC by adeptly scavenging chloride ions that emerge during the polymer’s thermal degradation process. The brilliance of ALCAMIZER lies in its ability to exchange the carbonate within its crystalline structure for these released chloride ions. By doing so, it establishes a robust bond that renders the chloride ions chemically inert, effectively halting any potential escalation of PVC/CPVC degradation. Earning accolades for their unparalleled efficacy, ALCAMIZER products stand as exemplars within their category, embodying the pinnacle of performance and reliability.
