| Silicone | High-temperature stability | Medical gadgets, automobile gaskets |
Types of Plastic Gaskets
Plastic gaskets can be found in different types, each serving particular requirements. Here are some of the most typical types:
1. Flat Gaskets
Flat gaskets are easy, circular or rectangle-shaped sealing components that fit in between 2 mating surfaces. These gaskets are often used in applications like valve covers, flanges, and piping connections.
2. O-Rings
O-rings are circular gaskets developed to fit snugly into a groove, developing a safe and secure seal. They are commonly used in hydraulic and pneumatic systems due to their reputable sealing ability.
3. Spiral Wound Gaskets
These gaskets include alternating layers of metal and filler material. They are developed for high-pressure and high-temperature applications, making them suitable for oil and gas industries.
4. Custom Gaskets
Customized gaskets are customized to particular applications, created to fulfill distinct dimensional, product, and efficiency requirements.
Table 2: Types of Plastic Gaskets and Their Uses
| Type | Description | Common Uses |
|---|---|---|
| Flat Gaskets | Basic shapes with even surface areas | Flanges, valve covers |
| O-Rings | Circular gaskets fitting into grooves | Hydraulic systems, pumps |
| Spiral Wound Gaskets | Layered gaskets for high pressure/temperature | Oil and gas, chemical processing |
| Custom Gaskets | Customized gaskets for specific applications | Different commercial applications |
