DEUTSCH Sealing Plug

The performance indicators of DEUSCH rubber seals mainly include the following aspects:

1. **Physical and mechanical properties**:

– **Hardness**: The hardness of the rubber seal is an important indicator that affects its sealing performance and wear resistance. Appropriate hardness ensures that the seal can maintain good shape and sealing effect under different working conditions. For example, a harder seal may be more suitable for high-pressure environments, while a softer seal may be better for applications requiring better flexibility.

– **Tensile strength**: It reflects the ability of the rubber seal to resist tensile forces. High tensile strength means that the seal can maintain its integrity and sealing performance when subjected to stretching or pulling forces during installation or use.

– **Elongation at break**: This indicates the extent to which the rubber seal can be stretched before breaking. A higher elongation at break value means better flexibility and adaptability of the seal, which is beneficial for installation in complex sealing structures and for withstanding certain degrees of deformation.

– **Compression set**: After being compressed for a long time, the rubber seal may have a certain degree of permanent deformation. A lower compression set value indicates that the seal can better maintain its original shape and sealing performance after being compressed, ensuring long-term stability of the sealing effect.

2. **Sealing performance**:

– **Leakage rate**: It is a key indicator to evaluate the sealing performance of the rubber seal. A low leakage rate means that the seal can effectively prevent the leakage of fluids or gases, ensuring the normal operation of the sealed system. The leakage rate is closely related to factors such as the material, structure, and installation quality of the seal.

– **Sealing force**: The sealing force refers to the force exerted by the rubber seal on the sealing surface to achieve a tight seal. Sufficient sealing force is necessary to ensure that the seal can closely adhere to the sealing surface and resist the pressure of the medium inside the sealed system to prevent leakage.

– **Dynamic sealing performance**: For applications where there is relative movement between the sealing parts, such as rotating shafts or reciprocating rods, the dynamic sealing performance of the rubber seal is crucial. It requires the seal to maintain good sealing performance while withstanding friction, wear, and the impact of movement, and to ensure that there is no leakage during the movement process.

3. **Temperature resistance**:

– **Low-temperature resistance**: In some low-temperature environments, the rubber seal needs to maintain good flexibility and sealing performance. The low-temperature resistance of the seal is reflected in its ability to maintain normal physical and chemical properties and sealing effect at low temperatures without becoming brittle or cracking.

– **High-temperature resistance**: In high-temperature working conditions, the rubber seal must be able to withstand high temperatures without significant deformation, aging, or loss of sealing performance. The high-temperature resistance of the seal is related to the material selection and formulation of the rubber, as well as the design and manufacturing process of the seal.

4. **Chemical resistance**: Depending on the specific application environment, the rubber seal may come into contact with various chemical substances, such as acids, alkalis, oils, and solvents. Therefore, it needs to have certain chemical resistance to resist the erosion of these chemical substances and maintain its sealing performance and physical properties.

5. **Aging resistance**: Over time, the rubber seal may be affected by factors such as oxygen, ozone, ultraviolet radiation, and heat, resulting in aging and deterioration. Good aging resistance means that the seal can maintain its performance and service life for a long time under normal use and storage conditions, reducing the frequency of replacement and maintenance.
