Plan a trial for your application
Tires or thick rubber parts
At the same thermal history, test scorch, state of cure and properties inside and at the surface of the article.
Predispersed ingredient sourcing
Compare compatibility with the base rubber by active content and carrier type.
Purchase specifications and incoming inspection
Review these properties when selecting and inspecting incoming material. Example figures refer to the cited grade or source. Confirm the offered specification, packaging and lead time in the quotation. LANXESS · TBBS rubber accelerator catalogue ↗
| Property | Unit | Published or agreed specification | Test conditions and checks |
|---|---|---|---|
| TBBS assay | % by mass | Confirm against the offered grade and purchase specification | State the powder grade or the active ingredient mass fraction in the masterbatch. |
| Initial melting point | °C | Confirm against the offered grade and purchase specification | Compare using the same measurement procedure. |
| Volatiles | % by mass | Confirm against the offered grade and purchase specification | Check temperature, drying time and condition of the as-received sample. |
When approving a sample, record the grade, methods, limits and specification revision. On receipt, match the packing lot number to the lot-specific COA and record the measured values and release decision.
From samples to commercial delivery
Packaging and receiving
Specify powder, granules or rubber masterbatch on the order. Include bag label and lot number.
Storage and handling
Follow grade-specific handling and transport documents. Retain the compound cure curve for batch validation.
Sample and order lead times
State the finished part, machine trial quantity and routine order size. Match trial and commercial grades and agree MOQ, load unit, lead-time start and arrival.
Questions from the plant
What if a thick part cures differently from a test sheet?
Compare core and surface temperature histories. Repeat with a specimen close to the actual thickness.
Why might an order stating only “NS” cause confusion?
Provide the full chemical name, TBBS abbreviation, required form and specification.
Report a delivery or batch issue
Include the order number, lot number from the package, label photos and inspection records for the affected lot. When retesting, check TBBS assay, Initial melting point, Volatiles.
