Overview
Executive Summary & Core Stabilization Mechanism
Preventing thermo-oxidative degradation is the biggest challenge when processing polymers at high temperatures. Without proper protection, heat and oxygen break down molecular chains, leading to yellowing, embrittlement, and premature product failure.
At Greenlano, we engineered our Antioxidant 1010 to solve this exact problem. It acts as a premium primary antioxidant additive, ensuring your plastic and resin formulations retain their strength, clarity, and performance throughout processing and long-term end use.
What is Greenlano® Antioxidant 1010?
Greenlano® Antioxidant 1010 (CAS 6683-19-8) is a high-molecular-weight sterically hindered phenolic antioxidant. Chemically known as Pentaerythritol tetrakis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate), it serves as a top-tier Irganox 1010 equivalent and Songnox 1010 alternative for global manufacturers.

Key Highlights & Value Drivers:
- High Thermal Stability: Resists extraction and volatile loss during hot melt extrusion.
- Low Color Contribution: Prevents discoloration and yellowing in clear or light-colored polymers.
- Broad Substrate Compatibility: Works seamlessly across polyolefins, engineering plastics, adhesives, and elastomers.
- Global Grade Standards: Delivers identical chemical performance to legacy market brands with superior cost efficiency.
Mechanism of Action: Radical Scavenging
During processing, exposure to heat and shear generates reactive free radicals (R• and ROO•). These free radicals kickstart an auto-oxidation chain reaction that breaks polymer backbones.
Greenlano® Antioxidant 1010 acts as a powerful polymer thermal stabilizer by halting this chain reaction before degradation spreads.
- Step 1 (Hydrogen Donation): The active sterically hindered phenolic groups donate sterically hindered hydrogen atoms to peroxy radicals (ROO•).
- Step 2 (Radical Neutralization): This reaction transforms harmful peroxy radicals into stable hydroperoxides (ROOH), cutting the auto-oxidation cycle short.
- Step 3 (Phenoxy Radical Resonance): The resulting antioxidant radical is stabilized through resonance across its bulky tert-butyl structure, preventing it from attacking the polymer chain.
By deploying four active phenolic heads per molecule, Antioxidant 1010 yields maximum radical-scavenging efficiency at minimal dosing rates.

Industry Applications & Substrate Compatibility
When manufacturing plastics and resins, thermal degradation can destroy your materials during processing and daily end-use. We developed Antioxidant 1010 to offer ultimate protection across a wide range of substrates, preventing yellowing, cracking, and loss of mechanical strength.
As a high-performance sterically hindered phenolic antioxidant, it acts as a primary antioxidant additive that neutralizes free radicals across diverse manufacturing processes.
Polyolefins & General Thermoplastics
Polyolefins face high thermal stress during extrusion and injection molding. Antioxidant 1010 serves as an essential polyolefin antioxidant stabilizer, safeguarding polymer chains against thermo-oxidative degradation.
- Polypropylene (PP): Protects melt flow index (MFI) stability and prevents yellowing during high-heat processing.
- Polyethylene (HDPE, LLDPE, LDPE): Maintains structural toughness and tensile strength in pipe, film, and blow-molding applications.
- Ethylene Vinyl Acetate (EVA): Prevents degradation in solar encapsulants and hot-melt formulations.
Engineering Plastics & Styrenics
High-performance engineering polymers require processing at elevated temperatures where standard stabilizers fail. Antioxidant 1010 provides low volatility and high extraction resistance.
| Polymer Type | Key Benefit | Typical Applications |
|---|---|---|
| ABS & HIPS | Retains impact resistance and prevents discoloration | Automotive trim, consumer electronics housings |
| Polyamides (Nylon / PA) | Limits heat aging during long-term continuous use | Under-the-hood automotive parts |
| Polyacetals (POM) & Polycarbonates (PC) | Maintains long-term clarity and mechanical integrity | Precision gears, optical components |
Elastomers, Rubbers & Synthetic Resins
Synthetic rubbers and elastomers suffer rapid degradation when exposed to oxygen and heat. Our Irganox 1010 equivalent stabilizes these matrix networks during polymerization and vulcanization.
- SBS & SIS Block Copolymers: Prevents polymer crosslinking and maintains elasticity.
- Polyurethane (TPU / PU): Blocks thermo-oxidative breakdown and preserves color purity.
- Synthetic Rubbers (BR, SBR, EPDM): Extends service life by preventing surface cracking and hardening.
Industrial Coatings, Adhesives & Lubricants
Beyond solid polymers, Antioxidant 1010 excels in fluid and semi-solid chemical formulations where long-term heat resistance is crucial.
- Hot-Melt Adhesives (HMA): Prevents charring, skinning, and viscosity shifts in pot life testing.
- Industrial Coatings: Protects powder coatings and synthetic enamel finishes from baking-oven yellowing.
- Lubricants & Greases: Serves as a reliable polymer thermal stabilizer, preventing sludge formation and fluid oxidation.
4. Processing Guidance & Dosing Matrix for Antioxidant 1010
How much primary antioxidant additive do you actually need to protect your polymer from thermo-oxidative degradation? Dialing in the right loading level keeps your processing stable while saving on raw material costs.
As a high-molecular-weight sterically hindered phenolic antioxidant, Antioxidant 1010 delivers long-term thermal stability at remarkably low concentrations.
Here is our recommended dosage matrix based on application type and substrate demand:
| Application / Resin Type | Typical Dosage (wt%) | Performance Focus |
|---|---|---|
| Polyolefins (PP, PE) | 0.05% – 0.25% | Prevents melt flow rate changes during extrusion |
| Engineering Plastics (PA, PBT, POM) | 0.10% – 0.50% | Retains tensile strength and heat resistance |
| Styrenics (ABS, HIPS, PS) | 0.10% – 0.30% | Inhibits discoloration and surface yellowing |
| Elastomers & Rubbers (SBR, BR, TPE) | 0.20% – 0.80% | Maintains elasticity and prevents crosslinking |
| Coatings, Adhesives & Polyurethanes | 0.15% – 0.50% | Extends pot life and prevents clear-coat degradation |
Pro Tip: High-shear extrusion processes or filled compounds (such as glass-fiber reinforced resins) typically require dosage levels near the higher end of these ranges.
4.2 Synergistic Co-Stabilizer Blends (Antioxidant 168 / Phosphites)
While Antioxidant 1010 acts as an exceptional primary antioxidant by scavenging free radicals, combining it with a secondary phosphite stabilizer creates a powerful synergistic defense system.
Why Use an Antioxidant 168 Synergistic Blend?
- Dual-Stage Protection: Antioxidant 1010 scavenges carbon-centered radicals during processing, while Antioxidant 168 decomposes hydroperoxides before they can initiate fresh polymer degradation.
- Color Stability: Blending a hindered phenolic antioxidant with a phosphite prevents yellowing during high-temperature injection molding or recycling loops.
- Processability: Reduces melt viscosity spikes and gel formation during multi-pass extrusion.
