The performance and temperature resistance of different rubber materials are crucial in engineering design and applications. Here are the performance and temperature resistance of some common materials:

1) Nitrile Rubber（NBR）:

Performance: good oil resistance and wear resistance, suitable for many liquid and oil environments.

Temperature resistance: usually can work in the temperature range of -40°C to +120°C, and specific formulas can provide a wider temperature range.

2) Silicone Rubber:

Performance: excellent high temperature resistance, aging resistance and electrical insulation, suitable for high temperature environment and food contact.

Temperature resistance: can work in the range of -50°C to +230°C, and some special formulas can even extend to higher temperatures.

3) NeopreneRubber （CR）:

Performance: good oil resistance and weather resistance, suitable for outdoor and automotive parts and other fields.

Temperature resistance: usually can work in the range of -30°C to +100°C, but its performance can also be improved by different vulcanization methods and additives.

4) Fluoro rubber (FKM):

Performance: excellent chemical resistance and high temperature resistance, suitable for sealing and corrosion resistance requirements under extreme conditions.

Temperature resistance: able to work in the temperature range of -20°C to over +200°C, it is one of the preferred materials in many high temperature and chemical environments.

5) EPDM:

Performance: excellent weathering resistance and water resistance, suitable for outdoor and water treatment applications.

Temperature resistance: usually able to work in the range of -40°C to +120°C, specific formulations can make it perform better in high temperature and chemical environments.

Choosing the right material depends on the specific application requirements, including temperature range, chemical environment, mechanical properties and other factors. Through reasonable material selection and process control, it can ensure that the product can operate stably and reliably under various environmental conditions.
