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:
Material | Lowest cold resistance | Maximum heat resistance | Outstanding features | Limitation |
Silicone Rubber | -70°C | +220°C / +270°C / +315°C |
|
|
VITON Rubber (VITON/FKM) | -30°C | +260°C |
|
|
EPDM Rubber | -50°C | +160°C |
|
|
Neoprene Rubber (CR) | -40°C | +140°C |
|
|
NBR Rubber | -35°C | +120°C |
|
|
NR Rubber | -50°C | +100°C |
|
|
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.
