Choose the wrong rubber material This causes the rubber seal to wear out quickly

simple rubber material that many people tend to overlook Because I think that they are the same, can be used interchangeably, affecting the usage. Rubber seals come with a shorter service life. But in fact, each type of rubber raw material There are different salient features and limitations of use.
At present, the rubber raw materials used in the production of Extruded Rubber Profile have many types for you to choose from. have outstanding features and has different usage restrictions as follows:

MaterialLowest cold resistance

Maximum heat resistance

Outstanding featuresLimitation
Silicone Rubber-70°C+220°C / +270°C / +315°C
  • Wide operating temperature range
  • Food grade properties
  • Resistant to UV Ozone and Weather
  • Smooth skin
  • Water resistant
  • Not oil resistant
  • Not resistant to high concentrations of chemicals
  • Poor mechanical properties
VITON Rubber (VITON/FKM)-30°C+260°C
  • Acid resistance, high chemical resistance
  • Oil resistant
  • Weather resistant
  • Not alkali resistant
  • Not resistant to hot water and steam
  • Poor mechanical properties
  • Not resistant to low temperature use
EPDM Rubber-50°C+160°C
  • Heat resistant
  • Chemical resistant
  • Resistant to UV Ozone and Weather
  • Impact resistant, bend resistant
  • Impact resistant, bend resistant
  • Not oil resistant
  • Not resistant to high concentrations of chemicals
Neoprene Rubber (CR)-40°C+140°C
  • Chemical resistant
  • Oil resistant
  • Excellent resistance to mechanical properties
  • Weather resistant
  • Not resistant to high concentrations of chemicals
NBR Rubber-35°C+120°C
  • Excellent oil resistance
  • Abrasion resistant
  • Water resistant
  • Weather resistant
  • Does not tolerate Brake Fluids
  • Not resistant to low temperature applications
  • Does not chemical resistant
NR Rubber-50°C+100°C
  • Water resistant
  • Resistant to hot water and steam
  • Low temperature resistant
  • Impact resistant
  • Not heat resistant
  • Chemical resistant
  • Not oil resistant
  • Short service life

 

If you choose raw materials that are not suitable for use, it can cause the rubber seal to deteriorate, such as  

CASE STUDY 1 The use of rubber seal raw materials made from EPDM rubber to be used in contact with oil results in swelling of the rubber seal. and deteriorate quickly In which this case must be selected as a rubber seal made from NBR rubber material instead of being able to use it in contact with oil

CASE STUDY 2 The use of rubber seal raw materials produced from NBR rubber raw materials to use in contact with oil. But the temperature is higher than 120 °C, it also causes the rubber seal to deteriorate quickly because the NBR rubber seal cannot withstand high temperatures, which this case can choose to use as CR rubber, oil resistant grade silicone or Viton rubber instead. depending on the operating temperature Other uses including joint costs

Therefore, when choosing raw materials for rubber, you must choose the one that is suitable for your application. which can consult the manufacturer Or let the Sales Engineer team of AlphaSeals brand (PTI Global Products Company Limited) take care of it.
