Long-term heat protection
Keeps tensile and impact properties through long service at elevated temperature, the main reason 1010 is the default phenolic in polyolefins.
Antioxidante 1010 Supplier for Long-Term Polymer Stabilization
SUNNOX® 1010 is a high-molecular-weight hindered phenolic primary antioxidant. It gives long-term thermal protection with very low volatility and extraction, in polyolefins, plásticos de engenharia, rubber and adhesives.
CAS 6683-19-8 · Hindered phenol · Primary antioxidant
Visão geral do produto
Antioxidante 1010 traps the free radicals that drive thermal oxidation, so plastics keep their strength and appearance through years of service at elevated temperature. Its molecular weight of 1177.6 keeps it in the polymer: it does not evaporate during processing and resists extraction by water and solvents. For processing stability it is normally blended with a phosphite such as 168, and with a thioester (DLTDP / DSTDP) where long-term heat aging is critical.
Typical specification. Every shipment is supplied with a batch COA; the limits that apply to your order are confirmed in the quotation and contract.
Key Benefits
Stays in the part
High molecular weight means low volatility in processing and low migration or extraction in use.
Broad compatibility
Used in PE, PP, POM, abdômen, PS, PVC, PA, BICHO DE ESTIMAÇÃO, PU, borracha, hot-melt adhesives and lubricants. Odorless and non-staining.

Applications by Polymer
Pick a material family to see how 1010 is normally used and what to confirm before your trial.
Polyolefins — PE & PP
The default long-term antioxidant for PP and PE pipe, filme, fiber and molded parts. Typically 0.05–0.3%, blended with 168 (1:1 ou 1:2 1010:168) for processing stability.
What to confirm for your application
- Resin grade and end use (cano, filme, fibra, molding)
- Service temperature and expected life
- Current antioxidant package and dosage
Engineering Plastics — POM, PA, BICHO DE ESTIMAÇÃO, abdômen
Used for heat-aging protection in POM, PA, PET/PBT, ABS and PS, often at the higher end of the dosage range for parts exposed to heat.
What to confirm for your application
- Polymer type and filler / glass content
- Heat-aging test you use (temperatura, horas)
- Color and odor requirements
Borracha, Hot-melts & Adesivos
Protects SBS, SIS, EPDM and EVA-based hot-melts and adhesives from oxidation during melting and storage, without staining.
What to confirm for your application
- Base polymer and tackifier system
- Melt-tank temperature and holding time
- Color stability target
PVC, Poliuretano & Lubrificantes
Used as a co-antioxidant in PVC and PU systems and as a high-temperature antioxidant in lubricants and oils.
What to confirm for your application
- System type and existing stabilizers
- Processing or operating temperature
- Solubility in your base oil or polyol
Embalagem & Storage
Embalagem
25 kg net in a plastic inner bag inside a paperboard drum or carton. Private-label packing on request.
Storage
Stable under normal conditions. Keep sealed, away from heat and moisture. See the SDS for full handling details.
Tempo de espera & terms
Typically 3–15 business days from order confirmation, depending on quantity. FOB, CIF or DAP to major ports.
Technical & Buying Information
Antioxidante 1010 Guia do comprador
Name the failure you want to prevent
Yellowing or melt-flow change during processing points to the phosphite share; embrittlement or cracking after months in service points to the phenolic and thioester share. Note recycled content and the number of extrusion passes.
Start from a proven blend
Most polyolefin packages start from a phenolic primary plus a phosphite secondary, then adjust. Send your current package and we suggest a starting blend for the trial instead of changing several variables at once.
Compare the numbers that matter
For powders: ensaio, melting range, volatiles and light transmittance at 425/500 nm (a direct read on color). Ask for the same parameters on our COA that appear on your incoming-inspection sheet.
Lock in supply terms
Agree packaging, monthly volume, destination port and required documents up front. A matching CAS number alone does not qualify a new source; run your trial and keep the approved lot COA as the reference.

Antioxidante 1010 ou 1076: which should I use?
Both are hindered phenolic primaries. 1010 (PM 1177.6) has lower volatility and extraction, so it is preferred for long service life and high-temperature use. 1076 (PM 530.9, melts at 50–55 °C) disperses more easily in film and low-temperature compounding.
What dosage of 1010 is typical?
0.05–0.3% in most polyolefins, higher for parts that must pass long heat-aging tests. Use it with 168 for processing stability. Confirm the level in your own heat-aging trial.
Is 1010 suitable for food-contact plastics?
1010 is widely used in food-contact polymers. Ask us for the grade-specific food-contact statement for your market before you start trials.
Can I get a sample before ordering?
Sim. Tell us the polymer, the test you plan to run and the quantity you need. Samples ship with a COA so you can compare the lot against your current material.
What if a COA does not match our agreed specification?
Send us the agreed specification and the COA showing the difference (parameter, unit and test method). We check it with the production batch record before you accept the material, and replace or re-test where the lot is out of specification.
