| Silicone | High-temperature stability | Medical gadgets, automobile gaskets |
Kinds Of Plastic Gaskets
Plastic gaskets can be found in numerous forms, each serving specific requirements. Here are a few of the most common types:
1. Flat Gaskets
Flat gaskets are basic, circular or rectangular sealing aspects that fit in between 2 mating surface areas. 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, producing a secure seal. They are widely utilized in hydraulic and pneumatic systems due to their dependable sealing capability.
3. Spiral Wound Gaskets
These gaskets include rotating layers of metal and filler product. They are developed for high-pressure and high-temperature applications, making them ideal for oil and gas industries.
4. Customized Gaskets
Custom gaskets are tailored to particular applications, created to fulfill distinct dimensional, material, and performance requirements.
Table 2: Types of Plastic Gaskets and Their Uses
| Type | Description | Typical Uses |
|---|---|---|
| Flat Gaskets | Easy 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 | Various commercial applications |
