High Temperature Resistance NBR Rubber Seal

 

 

Product Description

Introduce

High temperature resistance NBR rubber seal is a seal made using high-temperature resistance nitrile rubber, a synthetic rubber with excellent resistance to oil, abrasion, and chemical corrosion. It can still maintain its own elasticity and sealing performance in high-temperature environments, and will not become hard, brittle, or lose its sealing effect due to high temperatures. This type of seal is typically used in applications that require effective sealing in high-temperature environments, such as engines, heating equipment, water heaters, and high-temperature pipes. They can prevent liquid or gas leakage at high temperatures and ensure the normal operation and safety of the system.

Certification standard

Linde Polymer ensures stability and aging resistance by producing high-quality, temperature-resistant NBR rubber seals. Advanced machinery and technology are used in the manufacturing process, which includes rubber mixing, extrusion, and vulcanization. A robust quality control framework is implemented, encompassing raw material inspection, production monitoring, and final product inspection. These seals meet industry or international standards like ISO 9001, and some sectors could need further certifications. To guarantee consistent performance and dependable sealing in hot conditions, performance testing is also carried out. Linde Polymer uses many tests and verifications to guarantee the quality of its products.

• Gather supplies: Acquire raw nitrile rubber (NBR) that can withstand high temperatures and confirm that it satisfies the necessary quality requirements. Simultaneously, get ready any additional supplies and equipment that could be required, such as molds, fillers, and reinforcement materials.

• Mixing: Using a specified formula, combine nitrile rubber with other auxiliary elements (such as fillers and reinforcing materials). The goal of mixing is to completely combine the basic components to produce the desired chemical and physical qualities.

• Molding: Fill the prepared mold with the blended rubber material, then use molding techniques like pressing or extrusion to shape the rubber material into the desired seal shape. It's important to make sure the rubber material fills the mold completely and that the right pressure and temperature are maintained throughout the molding process.

• Vulcanization: To undergo vulcanization treatment, place the rubber seal that has been created into a furnace. The goal of vulcanization is to increase the physical and chemical qualities of rubber materials, such as their high-temperature tolerance, by subjecting them to a cross-linking process at a certain temperature and time.

• Post-processing: The rubber seal undergoes any required post-processing, such as edge trimming, cleaning, inspection, etc., once vulcanization is finished. Verify if the product's dimensions and look satisfy the specifications.

• Perform a quality check on the manufactured NBR rubber seal with high-temperature resistance. Dimensional inspection, hardness testing, tensile strength testing, temperature tolerance testing, etc. are examples of common testing items.

• Packaging and storage: To shield NBR rubber seals from the elements, pack them in a way that is suitable for high temperatures. It is best to store items out of direct sunlight and away from chemicals and to maintain the right humidity and temperature levels.

1. High resilience to temperature changes: High-temperature stability The elasticity and physical characteristics of NBR rubber seals can withstand high temperatures; they won't harden, crack, or lose their sealing ability as a result of the heat. Usually able to tolerate temperatures of 150 °C or more.

2. Oil resistance: NBR rubber resists swelling, softening, and cracking when it comes into contact with oil. It may continue to seal properly in the presence of gasoline, lubricating oil, and other petroleum-based liquids.

3. Chemical corrosion resistance: It can withstand the erosion of acids, alkalis, solvents, and other chemicals to a certain level while still retaining its sealing performance and service life. It has strong corrosion resistance to a variety of chemical compounds.

4. Sealing performance: It can successfully stop liquid, gas, or dust leaks and has good sealing performance. They can provide dependable sealing, guarantee regular system performance, and stop energy waste and degradation of the environment.

5. Mechanical characteristics: It can sustain a certain amount of pressure, distortion, and vibration, has strong elasticity and wear resistance, and continues to operate steadily over time.

6. Widely used: High temperature resistance NBR rubber seals are frequently used to meet sealing needs in a variety of hot settings, including gas turbines, motors, heating apparatuses, water heaters, stoves, and high-temperature pipelines. They are adaptable to a variety of application scenarios and industrial industries.
