Q1: What is the primary function of ActiSorb 405 in polymer processing?
A: ActiSorb 405 is a solid-phase catalyst designed to promote controlled dehydrochlorination and stabilization of polyvinyl chloride (PVC) and related chlorinated polymers during high-temperature processing, helping to suppress discoloration and degradation.
Q2: Is ActiSorb 405 compatible with common PVC stabilizer systems?
A: Yes, ActiSorb 405 is formulated to be compatible with calcium–zinc, barium–zinc, and organotin-based stabilizer packages, and it is typically used as a synergistic co-stabilizer rather than a standalone system.
Q3: How is ActiSorb 405 typically incorporated into PVC formulations?
A: It is generally added during dry blending or high-speed mixing stages, and is often pre-dispersed in plasticizers or carrier resins to ensure uniform distribution. Dosage depends on formulation requirements but typically ranges from 0.1% to 2% by weight of the polymer.
Q4: Does ActiSorb 405 require special handling or storage conditions?
A: Yes — it should be stored in a cool, dry place, protected from moisture and direct sunlight. Prolonged exposure to humidity may affect its physical form and catalytic performance, so sealed packaging and controlled ambient conditions are recommended.
