Frequently Asked Questions
Q: What is the recommended storage condition for Polymerization Inhibitor?
A: Polymerization Inhibitor should be stored in a cool, dry place away from direct sunlight and heat sources. Ideal storage temperature is between 15-25°C in tightly sealed containers to prevent moisture absorption and oxidation.
Q: How does Polymerization Inhibitor compare to other inhibitors like HQ or TBC?
A: Our Polymerization Inhibitor offers superior thermal stability compared to Hydroquinone (HQ) and maintains effectiveness over a wider temperature range than Tert-Butyl Catechol (TBC). It provides better color stability in final products and has lower volatility at elevated temperatures.
Q: Can Polymerization Inhibitor be removed from monomers before processing?
A: Yes, our Polymerization Inhibitor can be easily removed through standard purification methods such as alkaline washing, distillation, or adsorption processes. The removal efficiency typically exceeds 99% when proper procedures are followed.
