Q1: What is the primary function of ActiSorb G 1 in polymer processing?
A: ActiSorb G 1 is a solid-phase catalyst designed to promote controlled dehydrochlorination and stabilization of polyvinyl chloride (PVC) and related chlorinated polymers during high-temperature compounding and extrusion. It helps suppress discoloration and degradation by neutralizing acidic impurities and scavenging labile chlorine.
Q2: How does ActiSorb G 1 differ from conventional liquid or metal-based PVC stabilizers?
A: Unlike traditional metal soaps or organotin compounds, ActiSorb G 1 is a non-metallic, halogen-free, solid catalyst with low volatility and minimal impact on final product odor or extractables. Its heterogeneous nature provides gradual, sustained activity and improved compatibility with sensitive polymer blends and food-contact–grade formulations.
Q3: Is ActiSorb G 1 suitable for use in food-contact or medical-grade PVC applications?
A: ActiSorb G 1 is formulated to meet stringent purity requirements and has been evaluated for suitability in regulated applications. While final compliance depends on full system validation and regulatory review, it is commonly selected for compounds targeting food-contact and medical device applications where low migration and absence of heavy metals are critical.
Q4: What is the recommended method of incorporation into PVC compound formulations?
A: ActiSorb G 1 is typically added during dry-blending or high-intensity mixing prior to extrusion. Due to its fine particulate nature, it disperses readily in PVC resin and plasticizer systems. For optimal performance, ensure uniform distribution—especially when used at low concentrations—and avoid prolonged exposure to moisture before processing.
