Powder
A powder form for your material evaluation. Discuss feeding, weighing, storage and preparation in relation to your existing process.
Discuss handling and the trial procedure.
HB / THE MATERIAL
Recovered carbon black.A practical blending option.
Tyre-derived recovered carbon black in powder and granular forms, with 20 kg, 500 kg and 1,000 kg packaging options. Evaluate a partial blend with virgin carbon black in your own industrial rubber compound.

01 / TWO MATERIAL FORMS
Powder or granules. Start with your process.
Choose the form for your material handling and mixing process, then evaluate it in the intended compound. Photographs show appearance; they do not define particle size or a performance grade.
Granules
A granular form for your material evaluation. Review granule condition, handling and dispersion during the compound trial.
Evaluate dispersion in the intended compound.
02 / PACKAGING OPTIONS
Three pack sizes. One clear supply plan.
Choose a pack size for your handling and purchasing requirements. Confirm the bag specification, pallet arrangement, markings and loading plan for each order.
20 kg
Small bag
Small-bag packaging; discuss palletisation and handling for the shipment.
500 kg
Half-tonne bulk bag
Bulk-bag packaging; confirm bag dimensions and the handling arrangement for the order.
1,000 kg
One-tonne bulk bag
Bulk-bag packaging; confirm the pack specification and loading plan for the order.
Bulk-bag photographs illustrate the packaging format. The 500 kg or 1,000 kg specification is confirmed in the order; a photograph alone does not identify the net weight.

Source: the HB batch comparison table. N330/N550/N660 are listed as typical industry reference ranges, rather than national-standard acceptance limits.
These are batch-specific figures. The reference sources, rubber formulation and test conditions were not supplied. The table does not establish grade equivalence or a replacement ratio.
* The N330 figure for stress at 300% elongation reads -0.5±1.5 in the original. It is retained as a source value requiring confirmation.

Source notes & items to confirm+
This layout transcribes the supplied table. It does not add a test, certification, laboratory endorsement or independent verification.
- The source prints 261021A / 2601021C. The second identifier has one more digit; both are retained without inferring a correction or a test date.
- Entries such as ≤0.5-0.7, ≤1.0-1.5 and ≤200-1000 are retained literally. The source does not explain how the inequality and range should be interpreted.
- The nitrogen-adsorption surface-area row does not specify total or external surface area. The last three rows print the unit as CN; confirm whether cN (centinewton) was intended.
- Method numbers are reproduced without edition years, as in the original. The three tensile properties are rubber-compound results; the same method number alone does not make different formulations directly comparable.
03 / PRODUCT APPROACH
One material decision. Three useful questions.
What material is being offered? How does it behave in your compound? What does the approved recipe cost? Start with these questions before choosing a blending level.
Identify the material
Confirm the proposed product, its source and the specification or supporting information available for that material.
Set an application benchmark
Choose one existing compound and record its processing conditions and the properties that determine product acceptance.
Compare the approved compound
Review trial performance, processing observations and the total material cost of the recipe before deciding on a purchase.
A FORMULATION DECISION
rCB + virgin carbon black.
A blend is a starting point for evaluation. The right level depends on your formulation, processing conditions and target properties.

04 / PRODUCT INFORMATION
Ask for the details that support your decision.
A product name and a price are only the beginning. Ask which specification applies, how the material is identified and what will be included in the proposed supply.
| Information to request | What to discuss |
|---|---|
| Material characteristics | Specification, reported properties and test methods; clarify typical values, agreed limits and the product reference. |
| Material form & handling | Powder and granular forms are offered. Confirm the selected form, storage and handling information, available safety documents and preparation for your process. |
| Batch information | Batch identification, available delivery records and how commercial supply can be compared with an evaluated sample. |
| Sample evaluation | Whether a sample is available, its identity, quantity, destination and any agreed sample or transport charges. |
| Purchase details | Choose 20 kg small bags, 500 kg bulk bags or 1,000 kg bulk bags. Confirm quantity, packaging details, currency, delivery basis, quotation validity and proposed dispatch timing. |
