Q1: What is the primary function of Puristar R3-16 in polymer processing?
A: Puristar R3-16 is a highly selective, regenerable adsorbent designed to remove low-molecular-weight impurities—such as residual catalysts, degradation by-products, and polar contaminants—from thermoplastic polymers during melt processing or compounding.
Q2: Is Puristar R3-16 suitable for food-contact or pharmaceutical-grade polymer applications?
A: Yes—Puristar R3-16 is manufactured under strict quality control and is widely used in purification processes for polymers intended for sensitive end uses, including food packaging and medical devices, provided final regulatory compliance is verified by the compounder according to applicable regional requirements.
Q3: How is Puristar R3-16 typically incorporated into a polymer system?
A: It is commonly added directly to the polymer melt stream via side-feeders or gravimetric dosing systems during extrusion or compounding. Due to its thermal stability and inertness, it remains physically intact throughout processing and can be separated post-purification using standard filtration or screen-changer systems.
Q4: Can Puristar R3-16 be regenerated and reused?
A: Yes—this adsorbent is engineered for multiple regeneration cycles via controlled thermal treatment under inert atmosphere, enabling significant cost and waste reduction in high-volume production environments. Regeneration efficiency depends on contaminant load and process history.
