| Silicone | High-temperature stability | Medical devices, automobile gaskets |
Types of Plastic Gaskets
Plastic gaskets been available in various kinds, each serving particular requirements. Here are a few of the most typical types:
1. Flat Gaskets
Flat gaskets are easy, circular or rectangle-shaped sealing aspects that fit between 2 mating surfaces. These gaskets are often utilized in applications like valve covers, flanges, and piping connections.
2. O-Rings
O-rings are circular gaskets designed to fit comfortably into a groove, producing a safe and secure seal. They are widely used in hydraulic and pneumatic systems due to their reliable sealing ability.
3. Spiral Wound Gaskets
These gaskets consist of rotating layers of metal and filler material. They are designed for high-pressure and high-temperature applications, making them suitable for oil and gas markets.
4. Customized Gaskets
Customized gaskets are tailored to particular applications, developed to satisfy unique dimensional, material, and performance requirements.
Table 2: Types of Plastic Gaskets and Their Uses
| Type | Description | Typical Uses |
|---|---|---|
| Flat Gaskets | Basic shapes with even surfaces | 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 particular applications | Different industrial applications |
