Buyer intent coverage

Industrial-Grade Stearic Acid — what it is, where it is used, how it is chosen

Stearic acid (C17H35COOH) is a saturated C18 fatty acid supplied in single, double or triple pressed grades and in flake, bead or molten form. It is a rubber activator, external lubricant, mould release and feedstock for metallic stearate production.

Primary uses

  • Rubber and tyre activator in cure systems
  • External lubricant and mould release in rigid PVC extrusion
  • Feedstock for calcium / zinc / magnesium stearate production
  • Structural component of candles and personal-care bases

Applications

  • Tyre and technical rubber compounding
  • Rigid PVC pipe, profile and fittings extrusion
  • Metallic stearate plants
  • Candle formulations
  • Personal-care fatty-phase bases
  • PP mould-release applications

Advantages

  • Well-defined iodine value / colour / free-fatty-acid specification per press grade
  • Multiple forms (flake / bead / molten) for handling flexibility
  • Compatible with global rubber and PVC formulations

Limitations to consider

  • Press grade is not marketing — single, double and triple pressed differ measurably in colour and iodine value
  • Palm and tallow feedstocks track different commodity cycles and are traceable only when the letter of origin is on file
  • Molten handling requires jacketed and temperature-controlled equipment

How to choose the right grade

  • Triple pressed where light colour and low iodine value are process-critical (rubber activator, cosmetic)
  • Double pressed for general PVC external lubricant
  • Single pressed for stearate feedstock and industrial mould release
  • Select form against handling (flake / bead / molten)

Typical grades

  • Single pressed
  • Double pressed
  • Triple pressed

Comparable materials — how Industrial-Grade Stearic Acid sits against alternatives

  • Palmitic acid — different C16 chemistry
  • Zinc / calcium stearate — pre-neutralised salts
  • Paraffin wax — release-only applications

Comparable-material reference. Grade selection is confirmed at RFQ against your process.

About this product

Industrial-Grade Stearic Acid — product overview

AllZone-STA800 is an industrial-grade stearic acid used as an external lubricant and mould-release accelerator, and as a raw material in the production of metallic stearates. Primary industrial buyers include tyre and rubber compounders, rigid uPVC extruders (mould release, calender release) and downstream stearate producers (calcium, zinc, magnesium stearate). Grade selection is driven by the iodine value, moisture, colour and free-fatty-acid content required by the buyer's process; these parameters are confirmed on the batch COA. Packaging and origin references are recorded at RFQ.

Document & COA status
  • • TDS: Verified product TDS available below.
  • • SDS: Safety data is subject to grade and supplier confirmation. One SDS does not necessarily apply to every grade or supplier.
  • • COA: Certificate of Analysis is provided against the confirmed shipment, grade and batch. No stock, lead-time or regulatory claim is implied without written confirmation.

Pricing & Market Factors

What drives the price of Industrial-Grade Stearic Acid in Canada

Current pricing is confirmed through a live quotation because industrial material costs depend on grade, volume, origin, packaging, freight and delivery location, and move with global commodity, ocean-freight and CAD/USD cycles. Allzone does not publish spot prices — the drivers below help you frame the RFQ.

  • Press grade. Single, double and triple pressed grades sit at distinct price bands driven by iodine value and colour.
  • Form. Flake vs. bead vs. molten changes handling cost and freight.
  • Feedstock. Palm and tallow feedstocks track different commodity cycles; global oleochemical spreads matter.
  • Volume & freight. High-tonnage buyers see meaningful freight optimisation from mixed-container planning.

Buyer FAQ

Questions Canadian buyers ask about Industrial-Grade Stearic Acid

What is stearic acid used for industrially?
Stearic acid (C17H35COOH) is used as a rubber activator, external lubricant and mould release in rigid PVC extrusion, feedstock for calcium / zinc / magnesium stearate production, and in candle-wax and personal-care formulations.
What is the difference between single, double and triple pressed stearic acid?
Pressing removes olein and colour bodies. Triple pressed has the highest purity, lightest colour and lowest iodine value — typical for cosmetic and rubber activator use. Double pressed sits between. Single pressed is lower purity and typical for industrial mould-release and stearate feedstock.
Which grade of stearic acid fits rigid PVC compounding?
Rigid PVC extruders typically use double or triple pressed stearic acid as an external lubricant / mould release. Exact grade depends on the calcium-zinc stabiliser system and processing window; confirm on your line before scaling.
Do you supply stearic acid in Ontario and Quebec?
Yes. Allzone serves rubber, PVC, stearate and personal-care buyers across Ontario, Quebec and the rest of Canada. Grade selection, packaging (flake / bead / bag / super-sack) and freight mode are confirmed at RFQ.
What information should a stearic acid quotation request include?
State the intended process (tyre / rubber / uPVC release / stearate production), press grade required (single / double / triple), form (flake / bead), required iodine value / free-fatty-acid / colour targets, packaging, destination and monthly volume.
