Anti-Oxidants
Allzone Trading supplies anti-oxidants to plastics processors, compounders and manufacturing plants in Toronto, the GTA, Ontario, Quebec and across Canada. Antioxidants protect polymers from thermal and oxidative degradation during processing and in service, and are typically supplied as primary/secondary blends. Grade and specification are confirmed against supplier documentation at quotation.

Buyer intent coverage
Antioxidants for plastics — what it is, where it is used, how it is chosen
Antioxidants protect a polymer twice: primary hindered phenolics scavenge the radicals that cause long-term ageing, while secondary phosphites decompose peroxides formed during melt processing. Compounders and recyclers are the main buyers, because every additional heat history consumes stabiliser. In practice most purchases are one-pack blends designed for a specific polymer and process rather than single chemistries bought separately.
Primary uses
- Protecting polymers during melt processing and regranulation
- Extending long-term thermal stability in service
- Restoring stabiliser levels in recycled polymer streams
- Preventing yellowing and property loss on repeated heat history
Applications
- Compounding and masterbatch production
- Recycled polyolefin reprocessing
- Pipe, cable and technical compounds with long service life
- Film and moulding grades exposed to multiple heat cycles
Advantages
- Protects both the process and the service life of the finished part
- One-pack blends simplify dosing and reduce weighing errors
- Directly supports higher recycled content in compounds
Limitations to consider
- Some phenolic chemistries can contribute to discolouration in specific systems
- Stabiliser is consumed over time, so protection is finite
- Ultraviolet damage needs a light stabiliser; an antioxidant alone does not cover outdoor exposure
- Addition rate and performance are established on your own line; the figures quoted in supplier literature are starting points, not a specification.
How to choose the right grade
- Start from the defect or property you are trying to fix, then work back to the chemistry family
- State the base polymer and the process, because the same function is delivered by different chemistries in different resins
- Confirm the maximum processing temperature the additive must survive
- Confirm the regulatory status the finished part requires before shortlisting grades
- Decide whether you want the active as a neat additive or carried in a masterbatch for easier dosing
- Exact specification is confirmed against supplier documentation at quotation.
Typical grades
- Hindered phenolic grade
- Phosphite grade
- Thioester grade
- One-pack blend for a specific polymer
- Food-contact grade where the application requires it
- Reference grade names are widely used as shorthand in enquiries. They are treated here as search language only: an equivalent is confirmed by comparing declared datasheet values and by a line trial, and no grade is presented as a drop-in replacement for another.
Comparable materials — how Antioxidants for plastics sits against alternatives
- UV stabilizer packages for light-driven degradation
- Process temperature reduction
- Higher-stability base resin grade
- Buyers searching for an alternative or second-source supplier should state the incumbent grade and the property they are matching, because a like-for-like comparison depends on the declared datasheet values and on line trials, not on the material name alone.
Comparable-material reference. Grade selection is confirmed at RFQ against your process.
Procurement coverage
How to specify, order and receive Antioxidants for plastics
Written for procurement, quality and technical buyers in Canada and the United States. No numeric price, MOQ, stock or lead-time value is published — those are confirmed per shipment in the quotation and against the confirmed batch.
How buyers specify at RFQ
- Base polymer and process the additive is dosed into
- Function required and the defect being corrected
- Physical form (powder, pellet, liquid or masterbatch) your dosing equipment accepts
- Processing temperature window the additive must survive
- Regulatory status required for the finished part
- Compatibility with the other additives already in the formulation
Packaging options (industry-standard)
- 25 kg bag or box — the usual format for dosing-unit refills
- Jumbo / FIBC bag for continuous gravimetric feeding on high-output lines
- Moisture-barrier or foil-lined packaging for hygroscopic and oxidation-sensitive actives
- Packaging options and available pack sizes are confirmed with each quotation.
Storage & handling
- Store cool, dry and sealed; heat and humidity degrade both carrier and active
- Keep concentrates in closed containers to avoid contamination of natural or light-colour runs
- Use first-in, first-out rotation and respect any retest or shelf-life date on the batch
Documentation available
- Technical data sheet (TDS) stating the active chemistry, carrier and recommended addition range
- Safety data sheet (SDS) in the format required for Canadian import
- Certificate of analysis (COA) against the confirmed batch
- Food-contact or regulatory declaration where the converted part requires it
- Documentation is confirmed per batch at quotation; availability depends on the grade and supplier offered.

Technical & procurement detail
Where anti-oxidants is used+
Antioxidants protect polymers from thermal and oxidative degradation during processing and in service, and are typically supplied as primary/secondary blends. It is quoted for the specific process, machine and end-application described in the enquiry, because performance depends on the processing window rather than on a single published value.
Grades are not interchangeable+
Different grades of anti-oxidants are supplied and quoted as separate specifications. A grade supplied for one process, resin system or end-use is not presented as suitable for another. State the resin, process, machine type and end-application in your enquiry so the correct grade and documentation are reviewed with the supplier.
How specifications are confirmed+
Allzone does not publish assumed purity, melt index, loading level, particle size, origin, certification, regulatory approval, packaging or price values. Grade, specification and documentation are confirmed in writing against supplier technical data sheets and safety data sheets before an order is placed.
Frequently asked questions
What grade of anti-oxidants do you supply?+
The grade and specification are confirmed at quotation against the supplier technical data sheet. No specification or certification value is published in advance.
Can I request a technical data sheet and a safety data sheet?+
Yes. Both the supplier technical data sheet and the safety data sheet for the quoted grade are provided on request and should be reviewed before purchase and use.
Do you deliver anti-oxidants across Ontario and Quebec?+
Yes. Freight is arranged across Toronto, the GTA, Ontario, Quebec and Western Canada, and the delivery method is confirmed with the quotation.
What quantities can you supply?+
Quantities are reviewed per enquiry, from single pallets to full container loads.
