| EPDM | Excellent UV and ozone resistance | Automotive seals, roofing membranes |
| Silicone | High-temperature stability | Medical gadgets, automobile gaskets |
Types of Plastic Gaskets
Plastic gaskets been available in numerous types, each serving particular requirements. Here are a few of the most typical types:
1. Flat Gaskets
Flat gaskets are easy, circular or rectangular sealing components that fit between two mating surface areas. These gaskets are typically used in applications like valve covers, flanges, and piping connections.
2. O-Rings
O-rings are circular gaskets created to fit comfortably into a groove, developing a safe and secure seal. They are commonly utilized in hydraulic and pneumatic systems due to their dependable sealing ability.
3. Spiral Wound Gaskets
These gaskets consist of alternating layers of metal and filler product. They are designed for high-pressure and high-temperature applications, making them ideal for oil and gas industries.
4. Custom-made Gaskets
Custom-made gaskets are customized to specific applications, developed to fulfill unique dimensional, material, and efficiency requirements.
