| Silicone | High-temperature stability | Medical gadgets, automobile gaskets |
Kinds Of Plastic Gaskets
Plastic gaskets can be found in various types, each serving specific requirements. Here are a few of the most typical types:
1. Flat Gaskets
Flat gaskets are basic, circular or rectangular sealing elements that fit between 2 mating surfaces. These gaskets are typically utilized in applications like valve covers, flanges, and piping connections.
2. O-Rings
O-rings are circular gaskets created to fit snugly into a groove, creating a safe and secure seal. They are extensively utilized in hydraulic and pneumatic systems due to their trustworthy sealing capability.
3. Spiral Wound Gaskets
These gaskets include alternating layers of metal and filler product. They are created for high-pressure and high-temperature applications, making them suitable for oil and gas markets.
4. Customized Gaskets
Custom gaskets are tailored to specific applications, developed to meet unique dimensional, material, and efficiency requirements.
