ISMAT manufactures Cerulean NR 11 as a sulphur curable natural rubber compound, validated through in-house testing to ensure consistent quality across every batch. With an elongation at break of 350% minimum, this compound offers exceptional stretch and flexibility, backed by excellent mechanical properties and abrasion resistance that hold up well under repeated wear.
This combination of high elongation and good wear resistance makes Cerulean NR 11 a strong fit for grommets, anti vibration mounts and rubber-to-metal bonded parts, where the material needs to absorb mechanical shock and vibration without cracking or degrading over time. It also performs reliably in refrigeration seals, pumps, and cable wire applications across its -40°C to +70°C operating range.
If your application calls for a resilient, wear-resistant rubber that can flex repeatedly under mechanical load, Cerulean NR 11 is worth considering. Contact ISMAT to confirm it fits your specific application requirements.
