SBR and NBR grades are used across a wide range of rubber products. A useful material review starts with the finished product, service environment and production process, then checks the candidate grade in the buyer’s own formulation.
Start with the application
Tell us what the part does, what it contacts, the working temperature, target hardness and production method. These details are more useful than selecting a grade from a name alone.
Seals and Gaskets
Review fluid contact, temperature, compression requirements and dimensional stability.
Hoses and Rollers
Consider conveyed media, pressure, abrasion, surface contact and processing consistency.
Footwear and Moulded Parts
Compare process, colour, hardness, wear and the finished-product specification.
Information to Provide
- Finished product and end-use environment
- Current producer and grade, if available
- Process, hardness and key test requirements
- Trial quantity, regular demand and destination
- Required TDS, SDS or COA documents
Application Review
Linwell can help organize the inquiry, compare available documents and discuss candidate SBR or NBR grades. Final material approval remains with the buyer after formulation and production testing.
