Material for rubber seals: NBR, SBR, EPDM
Rubber gaskets are a very important component of many technical systems, providing tightness, durability and resistance to a variety of environmental factors. Choosing the right material for rubber seals is crucial to ensure optimum product functionality and longevity. The most common rubber gasket materials are NBR, SBR and EPDM.
Rubber gaskets play a key role in many industries and everyday applications. Thanks to their unique properties, such as their flexibility, resistance to a variety of chemical agents, and ability to form tight joints, these seals are used in a wide variety of fields. Here are some of the main areas where rubber gaskets are used:
- Automotive industry: rubber seals are commonly used in automotive engines, brake systems, air conditioning systems and vehicle doors and windows.
- Hydraulic and Pneumatic Industry: Rubber seals are essential in hydraulic and pneumatic systems, where robust connections are required that can withstand high pressures and a variety of chemical agents.
- Food and Pharmaceutical Industry: Due to their resistance to chemicals and ability to maintain hygiene, rubber seals are used in food processing equipment and medical equipment.
- Construction: In the construction industry, rubber seals are used in windows, doors, ventilation systems and various plumbing systems.
- Domestic appliances: Rubber seals are also an important component in domestic appliances such as washing machines, refrigerators and dishwashers.
- Electronics: In electronics, rubber seals protect delicate components from dust, moisture and vibration, which increases the durability and reliability of equipment.
- Aerospace: High-quality rubber seals are used in aerospace constructions where exceptional durability and resistance to extreme conditions are required.
Rubber seals are an indispensable component of many systems and equipment, ensuring their long-term and reliable operation. Thanks to the continuous development of rubber material production technology, their properties are constantly being improved, allowing them to be used even more widely and effectively in the future.
The most popular materials for rubber seals
NBR (Nitrile Butadiene Rubber)
Features and applications
NBR, also known as Nitrile Butadiene Rubber, is one of the most popular materials used for rubber gaskets. It is distinguished by its exceptional resistance to oils, fats and other chemicals. Thanks to these properties, NBR is often used in the automotive, oil and hydraulic equipment industries.
Advantages of NBR:
- Resistance to oils and fuels
- Excellent abrasion resistance
- Good mechanical strength
Disadvantages of NBR:
- Limited weather resistance
- Poor ozone and UV resistance
SBR (Styrene Butadiene Rubber)
Features and applications
SBR, or Styrene Butadiene Rubber, is widely used due to its mechanical properties and low price. It is used in the manufacture of tyres, conveyor belts and a variety of seals that are not exposed to aggressive chemicals.
Advantages of SBR
- Good mechanical strength
- Abrasion resistance
- Low price
Disadvantages of SBR
- Low oil and chemical resistance
- Limited resistance to weathering
EPDM (Ethylene Propylene Diene Monomer)
Features and applications
EPDM is a material that is characterised by exceptional resistance to weather, ozone and UV radiation. Thanks to these properties, EPDM gaskets are often used in the construction industry, the automotive industry and in water installations.
Advantages of EPDM
- Excellent resistance to atmospheric conditions
- Resistance to ozone and UV radiation
- Good flexibility at low temperatures
Disadvantages of EPDM
- Poor oil and chemical resistance
- Lower mechanical strength than NBR
