What are the advantages of using NBR or silicone rubber materials for the sealing gaskets of the refrigerator water filter-KR series in maintaining the sealing of the water filter?

NBR material can fit the various connecting parts of the water filter accurately and tightly, effectively preventing any tiny leakage of water during the filtration process. This excellent sealing not only ensures the maximization of the filtration effect, but also ensures the safety and purity of the final water quality. Considering that the refrigerator water filter may be exposed to water containing a small amount of grease under certain circumstances, the NBR material shows its extraordinary oil resistance. This feature enables the NBR sealing gasket to maintain stable sealing performance in an environment with long-term contact with grease, and is not easily eroded or failed, thereby extending the overall service life of the water filter.
During the installation, disassembly and daily maintenance of the water filter, the sealing gasket will inevitably experience a certain degree of friction and wear. With its excellent wear resistance, the NBR material can effectively resist the erosion of these external forces and reduce the decline in sealing performance caused by wear. This not only reduces the frequency of users replacing sealing gaskets, but also saves maintenance costs and improves the overall cost performance of the product.
Silicone rubber, with its excellent sealing performance, is not only reflected in normal temperature and humidity environment, but also can remain stable under extreme temperature and humidity conditions. The interior of the refrigerator is usually maintained at a relatively low temperature, which places high demands on the cold resistance of the sealing material. Silicone rubber can remain soft and elastic in an environment as low as dozens of degrees below zero, effectively preventing hardening or cracking caused by low temperature, and ensuring the tightness of the water filter connection. At the same time, although the direct application inside the refrigerator does not involve a high temperature environment, the high temperature resistance of silicone rubber also provides it with the possibility of a wider range of applications, showing its excellent adaptability and durability.
Over time, many materials will age due to environmental factors, showing performance degradation or even failure. However, silicone rubber stands out with its excellent aging resistance. Even during long-term use, it can effectively resist aging and maintain its original physical and chemical properties. Silicone rubber sealing gaskets can maintain a stable sealing effect for a long time, without frequent replacement, reducing the user's maintenance cost, and also reflecting the high quality of the product.
In the field of drinking water filtration, the safety of materials is crucial. As a strictly certified non-toxic and harmless material, silicone rubber fully complies with food safety standards, does not contain harmful substances, and will not release any harmful components to the human body during contact with water. This feature makes silicone rubber sealing gaskets an ideal choice for ensuring the safety of drinking water, allowing users to enjoy pure water treated by the water filter without worrying about health risks caused by material problems.
During the use of the water filter, its connecting parts may undergo slight deformation or dislocation due to factors such as temperature changes and external forces. With its high elasticity, silicone rubber sealing gaskets can flexibly adapt to these changes to ensure that the sealing performance is not affected. This high elasticity not only enhances the durability of the sealing gasket, but also improves the overall stability and reliability of the product, allowing the refrigerator water filter-KR series to maintain excellent filtering effects in various complex environments.
Whether it is NBR or silicone rubber material, it can play an important role in maintaining the sealing of the refrigerator water filter. The specific material to be selected may depend on factors such as product design requirements, cost considerations, and usage environment.
