A Comprehensive Guide to Rubber Car Seals in China
Car door seals, also known as weatherstrips, are crucial components in automobiles. These rubber seals prevent water, dust, air, and noise from entering the vehicle cabin, enhancing comfort and vehicle longevity. China is a significant manufacturer and supplier of these seals, with companies like Hebei Shida Seal Group (www.shidarubber.com), Hebei Jintai Plastic and Rubber Products Co., Ltd (www.seal-strips.com), Jiangsu Ruyi Chemical Co., Ltd (www.ruyirubber.com), and Haining Chaoyue Seals Co., Ltd (www.chaoyuerubber.com) playing key roles in the industry. This guide delves into the technical aspects and diverse types of rubber car seals available from Chinese manufacturers.
Understanding Rubber Car Seal Technology
Rubber car seals are primarily made from EPDM (ethylene propylene diene monomer) rubber. EPDM offers superior resistance to various environmental factors, including ozone, sunlight, and water. Other materials like TPE/TPV and PVC are also utilized for specific applications. The manufacturing process often involves extrusion, molding, or a combination of both techniques to create the desired seal profiles. Hebei Shida Seal Group (www.shidarubber.com), for example, boasts state-of-the-art equipment for this purpose. The seals are often designed with adhesive backing or retaining clips for easy installation. Companies like Chaoyue (www.chaoyuerubber.com) offer various installation methods depending on customer needs.
Technical Features Comparison
The following table highlights key technical features of rubber car seals:
| Feature | Description |
|---|---|
| Material | EPDM, TPE/TPV, PVC, and blends |
| Hardness (Shore A) | Varies depending on application and material; typically ranges from 30 to 80 |
| Tensile Strength | Measures the material’s resistance to stretching; higher values indicate durability |
| Elongation | Indicates the material’s ability to stretch before breaking; higher values imply flexibility |
| Compression Set | Measures the permanent deformation after compression; lower values are preferred |
| Temperature Range | Operating temperature limits; varies with material selection |
| UV Resistance | Ability to withstand sunlight exposure without degradation |
| Water Resistance | Resistance to water absorption and damage |
| Ozone Resistance | Resistance to ozone degradation |
