Understanding Rubber Gasket Strip Technology
Rubber gasket strips are manufactured using various processes, primarily extrusion and molding. Extrusion creates continuous lengths of specific profiles, while molding shapes individual pieces. The choice of manufacturing process depends on the desired shape and volume. Material selection is crucial, as different rubbers offer varying properties. Common materials include EPDM, Neoprene, Silicone, and Nitrile. These materials are selected based on factors like temperature resistance, chemical compatibility, and required durability. Companies such as hcsealstrip.com specialize in custom extrusion, offering precise tolerances and a wide range of materials.
The technical specifications of rubber gasket strips are vital for proper functionality. Key features include hardness (Shore A), tensile strength, elongation, and compression set. These properties dictate the strip’s ability to withstand pressure, maintain its shape, and resist deformation over time. www.zhonggaoseals.com emphasizes the importance of professional technical advice to ensure optimal material selection.
| Feature | Description | Importance |
|---|---|---|
| Hardness (Shore A) | Measures the rubber’s resistance to indentation. | Determines the strip’s ability to withstand compression and maintain its seal. |
| Tensile Strength | Measures the maximum stress the rubber can withstand before breaking. | Indicates the strip’s resistance to tearing and stretching. |
| Elongation | Measures the rubber’s ability to stretch before breaking. | Crucial for applications requiring flexibility and the ability to conform to irregular surfaces. |
| Compression Set | Measures the permanent deformation after being compressed for a specific time. | Indicates the strip’s ability to maintain its shape and sealing effectiveness under prolonged compression. |
| Temperature Range | The range of temperatures the rubber can withstand without significant degradation. | Ensures the strip’s performance across various operating conditions. |
| Chemical Resistance | The rubber’s ability to withstand exposure to specific chemicals. | Essential for applications involving contact with oils, fuels, solvents, or other corrosive substances. |
