In the field of industrial sealing, the performance of gaskets is directly related to the stability, safety, and economy of equipment operation. As an innovative product that combines the advantages of polymer materials and metals, metal-reinforced PTFE gaskets have become an ideal choice for many high-demand industries such as chemical engineering, petroleum, pharmaceuticals, and food processing, thanks to their outstanding comprehensive performance.

I. Core Composition and Exquisite Manufacturing Process

The excellent performance of metal-reinforced PTFE gaskets stems from their scientific structural design and rigorous manufacturing process. These gaskets use 304 stainless steel or 316L stainless steel perforated plates as the core framework. Both materials not only possess excellent corrosion resistance, enabling them to adapt to a variety of complex working conditions, but also have outstanding mechanical strength, providing solid structural support for the gaskets.

During the manufacturing process, 100% pure polytetrafluoroethylene (PTFE) is used as the sealing base material. The pure PTFE and the metal perforated plate are tightly combined through a professional pressing process, followed by high-temperature sintering to form a solid integrated structure. This process not only ensures that there are no gaps or delamination between the PTFE material and the metal framework but also fully exerts the inherent advantages of the two materials, laying a solid foundation for the high performance of the gaskets.

II. Performance Advantages: Complementary Advantages to Break Through Traditional Limitations

The core value of metal-reinforced PTFE gaskets lies in the successful realization of performance complementarity between PTFE material and metal perforated plates, effectively solving the performance shortcomings of traditional pure PTFE gaskets while further enhancing the key sealing indicators.

1. Integration of Dual Performances, Balancing Sealing and Strength

These gaskets perfectly combine the excellent chemical resistance of 100% pure PTFE with the high tensile strength of metal perforated plates:

• The pure PTFE material itself is known as the "king of corrosion resistance". It can resist the erosion of most chemical media such as strong acids, strong alkalis, and strong oxidants, and can maintain stable chemical properties even in high-temperature environments, effectively avoiding sealing failure caused by medium corrosion;

• The metal perforated plate provides strong tensile strength for the gaskets, solving the problem that traditional pure PTFE gaskets have poor tensile performance and are prone to tearing due to stress during installation or use. This ensures that the gaskets always maintain a complete structural shape during long-term use.

The synergistic effect of these two performances greatly improves the sealing effect of the metal-reinforced PTFE gaskets, while significantly extending their service life. It reduces problems such as equipment shutdown and medium leakage caused by gasket damage, lowering the maintenance costs and safety risks of enterprises.

2. Making Up for Performance Shortcomings and Inhibiting Creep Relaxation

Traditional pure PTFE gaskets have two obvious defects: First, their compression rate and rebound rate are relatively low. It is difficult to achieve tight sealing through sufficient compression during installation, and during long-term use, once affected by external factors such as vibration and temperature changes, the rebound capacity of the gaskets is insufficient, which easily leads to gaps on the sealing surface and causes leakage. Second, PTFE material is prone to creep relaxation under long-term stress and high-temperature environments, that is, the gaskets will gradually produce plastic deformation, resulting in a decrease in sealing pressure and ultimately loss of sealing effect.

The metal-reinforced PTFE gaskets successfully solve these problems through the addition of metal perforated plates:

• The rigid structure of the metal perforated plate can provide effective support for the PTFE material. During installation and compression, the metal framework can guide the uniform distribution of the PTFE material, improving the overall compression rate of the gaskets. At the same time, the elastic recovery performance of the metal material can complement the rebound performance of the PTFE material, significantly increasing the rebound rate of the gaskets, ensuring that the gaskets can always fit tightly on the sealing surface during long-term use and maintain a stable sealing effect;

• The existence of the metal perforated plate can also effectively delay the creep relaxation process of the PTFE material. The high strength of the metal framework can limit the plastic deformation trend of the PTFE material, reducing the creep amount of the PTFE material under long-term stress. This allows the gaskets to maintain stable sealing pressure for a longer period, further extending the service life of the gaskets and improving the reliability of equipment operation.

III. Application Scenarios and Value Summary

With its excellent corrosion resistance, high strength, high sealing performance, and the ability to inhibit creep relaxation, metal-reinforced PTFE gaskets are widely used in scenarios with high sealing requirements and complex working conditions, such as chemical reaction kettles, petroleum pipelines, pharmaceutical equipment, and food processing machinery. Whether in strong corrosive medium environments, high-temperature and high-pressure working conditions, or equipment that requires long-term stable operation, these gaskets can provide reliable sealing guarantees.

In summary, through scientific structural design and exquisite manufacturing process, metal-reinforced PTFE gaskets perfectly integrate the advantages of PTFE material and metal material. They not only break through the performance limitations of traditional gaskets but also provide an efficient and reliable solution for industrial sealing with their outstanding comprehensive performance. They are an ideal choice for improving the stability of equipment operation, reducing safety risks, and saving maintenance costs in modern industrial production.
