SBR 1502 is a cold-polymerised emulsion styrene-butadiene rubber used in general-purpose and light-coloured rubber compounds. Buyers normally qualify it by producer specification, batch COA and a controlled compound trial rather than by grade name alone.
Why buyers specify SBR 1502
- Non-staining positioning: commonly considered for light-coloured, pigmented and general mechanical rubber goods.
- Balanced processing: suitable for conventional mixing and forming routes when the compound is adjusted to the supplied grade.
- Abrasion-oriented applications: widely evaluated for footwear, flooring, hoses, rollers and industrial moulded parts.
- Document-based qualification: Mooney viscosity, bound styrene, volatile matter, ash and cure behaviour should be checked using the supplier’s methods.
- Batch control: the TDS defines the specification framework while the COA identifies the actual supplied lot.
SBR 1502 supply overview
Linwell coordinates supply from approved sources and confirms producer, origin, packaging, current availability and document set for each quotation. Exact numerical limits are taken only from the offered producer’s current TDS and batch COA.
| Item | What it tells the buyer | Recommended action | Why it matters |
|---|---|---|---|
| Producer TDS | Supplier-specific specification and test methods | Compare with the approved material and formulation window | The same grade designation may not guarantee identical limits |
| Batch COA | Results reported for the offered or shipped lot | Check critical values before release to production | Lot-level evidence supports traceability and incoming control |
| Representative sample | Real processing and cure response in your compound | Run a controlled trial using documented conditions | Paper comparison cannot replace application testing |
| Packaging and lot plan | Bale format, quantity, palletisation and traceability | Confirm before purchase and record on receipt | Handling and identification affect production control |
Typical applications
Footwear and flooring
Soles, heels, mats and floor products can use SBR 1502 for a practical combination of abrasion resistance, processability and colour flexibility.
Mechanical rubber goods
Hoses, seals, gaskets, rollers and moulded items may use the grade when the formulation and finished-part requirements are validated.
Blends and filled compounds
SBR 1502 can be combined with reinforcing fillers, process oils, curing systems and other rubbers to tune cost and performance.
How to select and qualify the material
Define the operating environment and the production process before comparing suppliers. A useful request includes the finished product, service conditions, current material, critical raw-material controls, trial plan and commercial quantity.
| Decision input | What to provide or verify | Purpose |
|---|---|---|
| Mooney viscosity | Compare the producer’s test method and range with the approved material | Processing, mixing and extrusion behaviour can shift between lots |
| Bound styrene | Use the supplier’s declared method and specification | Polymer composition influences compound behaviour and properties |
| Volatile matter and ash | Review TDS limits and actual COA values | Incoming consistency and contamination control |
| Cure response | Test in the standard recipe and in the production compound | A passing raw-material COA does not prove identical cure behaviour |
| Finished-part tests | Repeat the tests that define your product approval | Qualification must close at component level |
Documents buyers should request
- TDS: current producer specification, declared characteristics and test methods.
- SDS: handling, storage, transport and safety information for the offered material.
- Batch COA: reported results and lot identity for the supplied batch.
- Origin and traceability: producer, country of origin, lot number, bale labels and packaging information.
- Commercial confirmation: quantity, lead time, Incoterm, shipment plan and document timing.
Packaging, storage and lot control
Confirm bale weight, wrapper type, pallet pattern, shipment quantity, production lot allocation and document delivery before placing the order. On receipt, preserve labels and lot identity and follow the producer’s storage guidance.
Quality and trial guidance
Use one controlled qualification record for the sample, trial batch and first commercial lot. Record mixer conditions, addition sequence, dump temperature, cure curve and finished-part results so that future lots can be compared on the same basis.
Prepare your inquiry
Send your application, current grade or producer, key specification window, trial quantity, annual demand and destination. Linwell will confirm the offered SBR 1502 source and provide the available technical documents for review.
