Clariant PolyMax 303 Catalyst – Frequently Asked Questions (FAQ)

Q1: What is the primary function of PolyMax 303 in polymer processing?

A: PolyMax 303 is a high-performance catalyst designed to accelerate crosslinking reactions—particularly in peroxide-cured elastomers and thermosetting polyolefin compounds—enhancing cure efficiency, scorch safety, and final mechanical properties without compromising process stability.

Q2: Is PolyMax 303 compatible with common peroxide initiators such as DCP or DBPH?

A: Yes, PolyMax 303 demonstrates broad compatibility with standard organic peroxides including dicumyl peroxide (DCP) and di-tert-butyl peroxide (DBPH), and is formulated to synergistically improve decomposition kinetics and network uniformity in demanding curing environments.

Q3: How should PolyMax 303 be incorporated into a compound?

A: It is typically added during the masterbatch or final mixing stage using standard internal mixers or twin-screw extruders. Good dispersion is achieved under typical shear conditions used for elastomer and thermoplastic compounding; pre-dilution in a carrier polymer or oil may be considered for highly sensitive formulations.

Q4: Does PolyMax 303 affect the thermal stability or aging behavior of cured products?

A: When used within recommended dosage ranges, PolyMax 303 contributes to more homogeneous crosslink networks, which generally supports improved long-term thermal stability and resistance to compression set—especially in dynamic sealing applications—but final performance depends on the full formulation and post-cure conditions.

Q5: What packaging options are available for PolyMax 303?

A: PolyMax 303 is supplied in sealed, moisture-resistant containers—including HDPE drums and multi-wall paper bags with inner liners—to preserve catalytic activity and ensure safe handling during storage and processing.
