Rubber seal products are widely used in industry and daily life, its role is to prevent gas or liquid leakage, protect equipment and personal safety. The selection of rubber seal product material has an important impact on its performance and service life. This paper will introduce the common rubber seal product materials and their characteristics.
Rubber seal products are mainly divided into natural rubber and synthetic rubber two categories. Natural rubber comes from rubber tree and has excellent resilience, insulation, water insulation and plasticity, so it is widely used in the manufacture of various rubber products. Synthetic rubber is synthesized by chemical methods, with wear resistance, oil resistance, high temperature resistance, aging resistance and other characteristics, and performs better in special occasions.
Natural rubber (NR) is one of the most common materials for rubber seals. It has excellent resilience, insulation, water insulation and plasticity characteristics, the price is relatively low. However, the performance of natural rubber is reduced in high temperature, oil and chemical environments, so its application scope is limited.
Styrene butadiene rubber (SBR) is a synthetic rubber with good wear resistance, heat resistance, oil resistance and aging resistance. Excellent performance in high temperature, oil and chemical environments, so it is widely used in automotive, aerospace, petrochemical and other fields.
Ethylene-propylene rubber (EPR) is a kind of synthetic rubber with excellent insulation, water insulation and weather resistance. It maintains stable performance in high temperature and chemical environment, so it is widely used in automotive, electrical, chemical and other fields.
Nitrile butadiene rubber (NBR) has excellent resistance to a variety of oils, solvents and chemicals, so it is widely used in petroleum, chemical, acid, alkali and other fields. It also has excellent wear resistance and cold resistance and can be used at lower temperatures.
Fluororubber (FKM) has a high degree of high temperature resistance, oil resistance, chemical corrosion resistance, can be used in high temperature and high pressure environment for a long time. It is widely used in automotive, petroleum, chemical, aerospace and other fields.
Silicone rubber (SIL) is a special rubber with excellent high temperature resistance, low temperature resistance, aging resistance and good air permeability. Silicone rubber is widely used in automobiles, electrical appliances, medical devices and other fields, especially in the need for sealing and insulation occasions.
In addition to the above common rubber seal product materials, there are other materials with special properties, such as acrylic rubber (ACM), polyurethane rubber (PU) and so on. These materials have excellent wear resistance, high temperature resistance and chemical corrosion resistance, so they are used in special situations.
When choosing the material of rubber seal products, it is necessary to choose according to the actual use environment and needs. For example, in high temperature environments, it is necessary to choose materials with good high temperature resistance; In the oil or chemical environment, it is necessary to choose materials with strong resistance to oil or chemicals. In addition, it is also necessary to consider the hardness, tensile strength, resilience, insulation and other physical properties of the material.
In short, there are many kinds of rubber seal products, and different materials have different characteristics and scope of application. In the selection of materials need to consider the actual use of the environment and needs, and comprehensive assessment. The correct material selection can ensure the performance and service life of rubber seal products, and provide protection for equipment and personal safety.
