Feature
Advantage:
- Being compounded to have tensile in the area of 1500 PSI and tear up to 200 lbs.
- Low compression set and good resilience.
- moderate solvent resistance.
- Excellent heat resistance.
- Good release characteristics.
- Extreme low temperature properties.
- Highly resistance to oxidation and ozone attack.
Disadvantage:
- Not recommended for most concentrated solvents, oils, concentrated acids and dilute sodium hydroxide.
