Phenolic Antioxidants

Phenolic Antioxidants (BHT, BHA, TBHQ, Tocopherols, Propyl Gallate, PG, AO-2246, Irganox® series)

Phenolic Antioxidants Primary chain-breaking stabilizers for high-performance polymers, lubricants, and fuels

Phenolic antioxidants are the cornerstone of oxidative stability in demanding industrial applications. By donating hydrogen atoms to free radicals, these hindered phenol-based compounds interrupt the autoxidation chain reaction, preventing polymer degradation, oil rancidity, and fuel gum formation during processing, storage, and end-use.

Our portfolio includes FDA/EU-compliant grades (BHT, TBHQ, tocopherols), high-temperature phenolics (Irganox® 1010, 1076, 1135), low-volatility oligomers, and non-staining/non-discoloring options for clear plastics and coatings. Available in free-flowing powders, dust-free granules, pumpable liquids, and polymer-specific masterbatches.

Key Benefits - Thermal Stability: Effective from 120°C to >300°C processing temperatures - Synergy: Boost performance 2–5× when blended with phosphites (e.g., 1:1 AO-1010/Irgafos® 168) - Migration Control: Non-blooming grades for food-contact films and medical devices - Color & Odor: Low-phenol, low-VOC grades for cosmetics and white goods

Typical Applications - Polyolefins (PE/PP recycle streams) - Engineering resins (PET, PBT, PC/ABS) - Synthetic lubricants (PAO, ester-based) - Rubber (SBR, EPDM tire compounds) - Fuel additives (gasoline, biodiesel)

All grades ship with TDS, SDS, and COA.
