| Silicone | High-temperature stability | Medical devices, automobile gaskets |
Kinds Of Plastic Gaskets
Plastic gaskets been available in various types, each serving particular requirements. Here are some of the most common types:
1. Flat Gaskets
Flat gaskets are easy, circular or rectangle-shaped sealing aspects that fit between two mating surfaces. These gaskets are often used in applications like valve covers, flanges, and piping connections.
2. O-Rings
O-rings are circular gaskets designed to fit comfortably into a groove, creating a safe and secure seal. They are extensively utilized in hydraulic and pneumatic systems due to their dependable sealing capability.
3. Spiral Wound Gaskets
These gaskets consist of rotating layers of metal and filler product. They are designed for high-pressure and high-temperature applications, making them appropriate for oil and gas markets.
4. Custom Gaskets
Customized gaskets are tailored to particular applications, designed to fulfill unique dimensional, material, and efficiency requirements.
