Bruggolen H175 Antioxidant – Frequently Asked Questions (FAQ)

Q1: What is the primary function of Bruggolen H175 in polymer systems?

A: Bruggolen H175 is a high-performance hindered phenolic antioxidant designed to protect polymers—especially polyolefins such as PP and PE—against thermo-oxidative degradation during processing and long-term service life. It acts by scavenging free radicals formed under heat and shear stress.

Q2: Is Bruggolen H175 suitable for food-contact or pharmaceutical-grade applications?

A: Bruggolen H175 is formulated for use in demanding industrial polymer applications. While it may be evaluated for specific regulatory compliance depending on regional requirements and final formulation, it is not pre-certified for food-contact or pharmaceutical use without further validation by the end-user and relevant authorities.

Q3: How does Bruggolen H175 compare to other common phenolic antioxidants in terms of volatility and extraction resistance?

A: Bruggolen H175 offers improved thermal stability and lower volatility compared to many standard monophenolic antioxidants, contributing to better retention during high-temperature processing. Its molecular structure also provides enhanced resistance to extraction in non-polar media, supporting longer-lasting protection in demanding environments.

Q4: What is the typical dosage range for Bruggolen H175 in polypropylene applications?

A: Dosage depends on the specific polymer grade, processing conditions, and performance requirements, but Bruggolen H175 is typically used at low concentrations—generally ranging from 0.1% to 2% by weight—in polypropylene formulations to achieve effective stabilization.

Q5: Can Bruggolen H175 be used in combination with other stabilizers?

A: Yes, Bruggolen H175 is commonly used synergistically with phosphite-based secondary antioxidants (e.g., tris(nonylphenyl) phosphite) and UV stabilizers to build comprehensive stabilization packages, particularly in applications requiring extended thermal aging resistance and outdoor durability.
