Product Details

DESCRIPTION

  • Widely known for its physical strength and retention of properties after long-term exposure to heat, oil, and chemicals. 

  • Depending on filler selection and loading, HNBR compounds typically have tensile strengths of 20 – 31 Mpa when measured at 23 °C. 

  • Compounding techniques allow for HNBR to be used over a broad temperature range, -40 °C to 150 °C, and 160 °C in oil, with minimal degradation over long periods of time. 

  • For low-temperature performance, low ACN grades should be used; high-temperature performance can be obtained by using highly saturated HNBR grades with white fillers. 

  • As a group, HNBR elastomers have excellent resistance to common automotive fluids (e.g., engine oil, coolant, fuel, etc.) and many industrial chemicals.
