Q1: What is the primary function of HDMax 300 in polymer processing?
A: HDMax 300 is a high-performance catalyst designed to accelerate crosslinking reactions—particularly in peroxide-cured elastomers and thermoset resins—enabling improved scorch safety, enhanced cure efficiency, and better final mechanical properties.
Q2: Is HDMax 300 compatible with common elastomeric systems such as EPDM, silicone, or fluorosilicone?
A: Yes, HDMax 300 demonstrates broad compatibility with saturated and unsaturated elastomers, including EPDM, silicone, and fluorosilicone compounds. Its formulation is engineered to minimize interference with filler dispersion and polymer stability during mixing and curing.
Q3: How should HDMax 300 be incorporated into a compound?
A: It is typically added during the final mixing stage—after base polymers, fillers, and other non-reactive ingredients—to ensure uniform distribution without premature activation. Pre-dispersion in a carrier oil or polymer masterbatch is recommended for optimal handling and dispersion.
Q4: Does HDMax 300 require special storage or handling precautions?
A: HDMax 300 should be stored in its original sealed container under cool, dry conditions away from direct sunlight and strong oxidizing agents. While not classified as highly hazardous, standard industrial hygiene practices—including gloves and eye protection—are advised during handling to avoid prolonged skin contact.
