Product Description
Introduce
Rubber gaskets with an EPDM round seal flat are used in sealing applications. EPDM is a synthetic rubber material that has superior resistance to heat, ozone, and chemicals. This round gasket is frequently used in equipment such as pumps, valves, pipelines, and other apparatus for sealing, isolating, and waterproofing purposes. The flat outside circular gaskets allow for intimate contact with adjacent surfaces to provide a trustworthy seal. They work well as sealants in a range of chemical media and may be utilized in both high and low temperature settings. Custom sizes, forms, hardnesses, and other specifications can be requested for these gaskets to satisfy specific requirements. To satisfy sealing demands, it is widely utilized in the construction, automotive, industrial, and electrical areas.


Certification standard
To make sure their products comply with the directive's criteria, suppliers and producers of electronic and electrical equipment must get RoHS certification. REACH compliance is guaranteed by Linde Polymer, especially for goods marketed in Europe. Chemicals such additives and anti-aging compounds that are prohibited by REACH laws may be present in the gasket. The NSF International-developed standards are pertinent to the treatment of drinking water and food safety. NSF/ANSI 51 for food equipment materials and NSF/ANSI 61 for drinking water treatment equipment materials are pertinent NSF standards. Water purity and safety are guaranteed by these criteria.

Advantage and Function
-
Excellent weather resistance: EPDM is very resistant to the effects of ozone, oxygen, UV radiation, and atmospheric conditions. It continues to function steadily and with durability over time in both indoor and outdoor settings.
-
Outstanding chemical resistance: It exhibits good resistance to a variety of chemicals, including solvents, bases, acids, and corrosives. Because of this, EPDM round seal flat gaskets work incredibly well in situations where they come into touch with different liquids and gases.
-
Broad temperature range: It may often be utilized in temperatures between -40 °C and +120 °C due to its large operational temperature range. In both hot and cold temperatures, it may retain its flexibility and sealing qualities.
-
Outstanding elasticity and recovery: After compression or deformation, it may regain its original shape because of its excellent elasticity and recovery. Because of this, circular gaskets may offer dependable sealing and adjust to various stress and deformation scenarios.
-
Electrical insulation performance: A superior material with good insulation properties and resistance to dielectric breakdown is utilized for electrical insulation. Because of this, EPDM round seal flat gaskets are frequently used in electrical and electronic devices.
-
Certification for drinking water: NSF/ANSI 61 criteria, for example, can be met by certain EPDM materials. Makes circular gaskets appropriate for use in water-contact applications, such water treatment machinery.
-
Good anti-aging qualities: EPDM is resistant to oxidation and heat degradation and has good anti-aging qualities. Long-term usage and exposure to hot temperatures won't affect the seals' ability to work consistently.

Application
-
Automotive industry: The production and maintenance of automobiles make extensive use of EPDM round seal flat gaskets. They serve as seals for the suspension system, doors, windows, sunroofs, engines, and more. Because EPDM materials are resistant to chemicals and weather, they offer dependable sealing under challenging automobile conditions.
-
Building & Construction Engineering: EPDM round seal flat gaskets are utilized in many applications such as pipe, roof, and door sealing, as well as window and door sealing. Building constructions are guaranteed to be sealed and long-lasting due to the resistance of EPDM materials to UV radiation and climatic conditions.
-
Electrical and electronic equipment: The insulating sealing of wires and cables, dust-proof sealing of electronic components, sealing of switches and control panels, and other applications are all common uses for this round sealing gasket in electrical and electronic equipment. EPDM can satisfy the needs of electrical and electronic equipment and has high chemical resistance and electrical insulating qualities.
-
Food and beverage industry: EPDM round seal flat gaskets that satisfy applicable certification standards can be utilized in a variety of applications that come into contact with food and drink, including equipment used for food processing, beverage filling, and food storage. These gaskets need to fulfill hygiene standards and food safety criteria.
-
Water treatment industry: Applications for circular sealing gaskets include water pumps, valves, filters, and other pipework and equipment connected to water treatment. To guarantee the dependability and security of water treatment systems, they must be resistant to chemicals and high temperatures.
-
Industrial Machinery and Equipment: Circular gaskets are employed in a range of industrial machinery and equipment to seal and isolate fluids, gasses, or dust. They can be utilized in pipe couplings, pumps, valves, pressure vessels, etc.
