Technical Data

Material: Sealing rubbers and gaskets are made from various materials depending on their application:

EPDM: Resistant to UV rays, ozone, moisture, and various chemicals.
NBR (nitrile rubber): Resistant to oil, fuel, and other aggressive substances.
Silicone: Withstands very high and low temperatures (typically from -60°C to +200°C) and is flexible.
Hardness: Usually between 40–80 Shore A (depending on required flexibility).
Temperature Resistance: Ranges from -60°C to +200°C, depending on the material.
Shape: Available as profiles (U, T, P shapes), strips, ring gaskets, sheets, or plates.
Color: Typically black, though customizable for specific needs (e.g., transparent silicone gaskets).
Applications

Industrial Equipment Sealing: Sealing rubbers are widely used to ensure the tightness of various industrial equipment, such as compressors, pumps, or valves, preventing leaks and enabling efficient control of liquid or gas flows.
Construction and Architectural Projects: Used to seal windows, doors, and roof structures to isolate from cold, noise, moisture, and wind.
Automotive and Transportation Industry: Sealing gaskets are widely used in cars, boats, trains, and other vehicles to isolate and protect against vibration, noise, and environmental effects.
HVAC Systems: Ensures the sealing of ventilation and air conditioning systems to prevent cold or warm air from penetrating unsuitable areas.
Food and Pharmaceutical Industry: Special food-grade silicone gaskets are used that withstand high temperatures and meet hygiene standards.
Advantages

High Tightness Level: Sealing gaskets protect against the penetration of liquids, gases, or dust, ensuring reliable sealing.
Resistance to Extreme Conditions: Depending on the material, rubbers and gaskets can withstand extreme temperatures, UV rays, chemicals, and mechanical wear.
Vibration and Noise Isolation: The elasticity of rubber gaskets effectively isolates vibrations and noise, making them useful in sensitive systems.
Flexibility and Customization: Various shapes and sizes allow easy adaptation to specific needs and different systems.
Cost-Effective Solution: Rubber gaskets are durable and easily replaceable, which makes maintenance and replacement cost-efficient.
Disadvantages

Limited Resistance to Specific Chemicals: Some rubbers, such as EPDM, are not resistant to oil-based substances, requiring the selection of suitable materials like nitrile rubber for such environments.
Aging Effects: Over time, rubber may lose elasticity and efficiency, especially in extreme conditions.
Temperature Limitations: Some gaskets (e.g., EPDM) are unsuitable for extremely high or low temperatures, necessitating careful material selection.
Dependence on Precise Installation: If sealing rubber or gasket is installed incorrectly, it may not ensure complete sealing, so careful installation is essential.
Sealing rubbers and gaskets are essential insulating elements in various industries, construction, automotive, and HVAC sectors. With their sealing capability, flexibility, and resistance to various environmental factors, these gaskets effectively protect against leaks, noise, vibration, and climate effects. However, when choosing a gasket, it is crucial to consider the operating conditions, as each material offers different resistance to temperature and chemical factors.
