Applications
Typical usage patterns. Tell us your base system, operating conditions, and constraints and we’ll align the right chemistry and specification. (Final suitability depends on the formulation and validation tests.)
Process fluids & lubricants
Supports oxidation resistance in compatible base oils/fluids; selection considers solubility, color limits, and deposit control strategy.
Specialty blends
Used where oxidation can drive viscosity increase, discoloration, odor formation, or performance drift; grade selected by compatibility and constraints.
What antioxidants typically help control
Performance outcomes depend on chemistry family, treat rate, and system conditions.
- Oxidation-driven viscosity increase and sludge/varnish tendency (system dependent)
- Discoloration and odor formation caused by oxidative degradation
- Property loss over thermal exposure (e.g., brittleness, loss of flexibility, reduced performance)
Technical overview
A practical view of how antioxidant families are selected in industry (final choice depends on validation and approvals).
Primary antioxidants
Often hindered phenolics or aromatic amines. Used to interrupt oxidation chain reactions and slow degradation.
Secondary antioxidants
Often phosphites/phosphonites or sulfur-containing types. Commonly used to decompose hydroperoxides and improve processing stability.
AO packages
Blends are used when both processing stability and long-term aging performance are needed, subject to compatibility and constraints.
Chemistry families we commonly source (examples)
We quote by family + spec window rather than a single “one-size-fits-all” grade.
Hindered phenolics
Broad-use stabilizers. Often selected for low odor, good compatibility in many systems, and long-term thermal aging support (grade dependent).
Phosphites / phosphonites
Often paired with phenolics to improve processing stability and reduce oxidative byproducts; selection depends on hydrolysis resistance and color constraints.
Aromatic amines
Often used where strong high-temperature oxidation resistance is required; selection depends on discoloration tendency and regulatory/customer constraints.
Selection checklist
These inputs usually decide the correct grade quickly.
- Compatibility / solubility in the base system (oil, polymer, solvent, blend)
- Temperature and volatility limits (processing and service exposure)
- Color & odor limits (especially for light-colored or low-odor products)
- Interaction with other additives (metal deactivators, antiwear, biocides, surfactants, etc.)
- Regulatory/customer declarations needed (where applicable)
Performance & validation support
Antioxidant selection is typically validated with a test method aligned to your industry and base system. Share your test method or acceptance criteria and we’ll match to a suitable grade window.
Oxidation stability tests
Commonly tracked outcomes include induction time, acid number increase, viscosity change, and deposit formation (method dependent).
Color & appearance
Light-colored systems often require tight color limits and good discoloration control under heat exposure.
Processing window
For compounding/extrusion, melt behavior and volatility can be decisive (grade dependent).
Typical technical data you can request
Availability depends on grade and lane.
- Assay / active content and impurity limits
- Melting point (solids) or pour point/viscosity (liquids)
- Color (APHA/Hazen or Gardner where relevant) and odor notes
- Solubility / compatibility guidance (system-dependent)
- Storage/shelf-life guidance and handling precautions (SDS)
Typical specifications & formats
Values depend on chemistry family and grade. Confirm details on quotation (TDS/COA).
