Q1: What is the primary function of HDMax 800 in polyolefin processing?
A: HDMax 800 is a high-performance peroxide decomposition catalyst designed to selectively control crosslinking and scission reactions during the melt processing of polyolefins—particularly in applications such as controlled rheology PP and crosslinked PE cable compounds.
Q2: How does HDMax 800 differ from conventional metal stearate catalysts?
A: Unlike traditional metal stearates, HDMax 800 offers enhanced thermal stability and more predictable decomposition kinetics, enabling finer control over molecular weight distribution without promoting excessive gel formation or discoloration under typical extrusion conditions.
Q3: Is HDMax 800 compatible with common polymer additives such as antioxidants and acid scavengers?
A: Yes—HDMax 800 has been formulated for compatibility with standard phenolic and phosphite antioxidants, as well as calcium-based acid scavengers, when used at typical dosage levels. However, interaction studies are recommended for formulations containing highly reactive co-additives.
Q4: What are the recommended handling and storage conditions for HDMax 800?
A: HDMax 800 should be stored in its original sealed container under cool, dry conditions, protected from moisture and direct sunlight. It is stable for extended periods when stored below 30 °C and away from strong oxidizing agents or reducing substances.
