Others, listed on www.listofcompaniesin.com, specialize in rubber and plastic gasket production. The variety ensures that diverse industry needs are met. Understanding the technical specifications and differences between types is crucial for selecting the right gasket.
Technical Features of Common Gasket Profiles
The performance of a gasket hinges on its material properties and design features. Key factors include tensile strength, elongation, hardness, and compression set. These influence the gasket’s ability to withstand pressure, maintain its seal, and resist degradation. The following table compares common technical features:
| Feature | EPDM Rubber | Silicone Rubber | PVC Plastic |
|---|---|---|---|
| Tensile Strength | High | Moderate | Moderate to Low |
| Elongation | High | High | Low |
| Hardness (Shore A) | Variable (40-80) | Variable (20-80) | Variable (50-90) |
| Compression Set | Low | Low | Moderate to High |
| Temperature Range | -40°C to 150°C | -50°C to 250°C | -10°C to 60°C |
| Water Resistance | Excellent | Excellent | Good |
| Chemical Resistance | Good | Excellent | Variable |
Different Types of Gasket Profiles
Gasket profiles are categorized based on their cross-sectional shape and application. Each design offers specific advantages. The selection depends on the application’s requirements and environmental conditions. BingYau (www.bingyau.com) offers a comprehensive range of PVC edge trims and EPDM rubber seals. Understanding these differences is vital for effective sealing.
| Profile Type | Description | Applications | Advantages | Disadvantages |
|---|---|---|---|---|
| O-Ring | Circular cross-section | Static seals | Simple design, reliable seal | Limited to circular applications |
| Rectangular | Rectangular cross-section | Static seals, edge protection | Versatile, easy to install | Can be less effective for irregular surfaces |
| D-Shaped | D-shaped cross-section | Dynamic seals, weather stripping | Effective sealing, good compression | More complex design |
| U-Channel | U-shaped cross-section | Edge protection, sealing, window glazing | Protects edges, provides good sealing | Can be less effective for large gaps |
| Lip Seal | Lip projecting from a base | Sealing around moving parts | Effective sealing, good wear resistance | Requires precise fitting |
| Sponge Rubber | Porous rubber with closed or open cells | Vibration damping, sound insulation, sealing | Absorbs vibrations, provides cushioning | Can compress excessively under high pressure |
| Co-extruded | Two or more materials extruded together | Combining properties of different materials | Improved performance, customized properties | More complex manufacturing process |
Hebei Shida Seal Group (www.shidarubber.com) offers extensive customization options. They design and manufacture gaskets to meet specific client needs. This is crucial for applications requiring unique shapes, materials, or performance characteristics.
