A Comprehensive Guide to Window Rubber Seals in China
Window rubber seals are crucial components ensuring weather resistance, noise reduction, and energy efficiency in buildings and vehicles. China is a major producer of these seals, offering a wide variety of options from different manufacturers. This guide explores the technical features, types, and considerations for selecting the right window rubber seal for your needs. Companies like Jiangyin Haida Rubber and Plastic Co., Ltd. (www.epdmrubberseal.com), Qingdao Seashore Industrial Co., Ltd. (www.extrusionrubber.com), and Hebei Shida Seal Group Co., Ltd. (www.shidarubber.com) are prominent players in this market.
Understanding the Technical Features
The performance of a window rubber seal depends heavily on its technical specifications. Key features include material composition, hardness, compression set, and temperature resistance. Manufacturers like www.shidarubber.com emphasize their expertise in material selection and testing to ensure product quality. Let’s compare some key technical features:
| Feature | EPDM Rubber Seal (Solid) | EPDM Rubber Seal (Sponge) | Silicone Rubber Seal |
|---|---|---|---|
| Material | EPDM | EPDM Sponge | Silicone |
| Hardness (Shore A) | 50-75 | 20-50 | 20-70 |
| Compression Set | Low | Moderate | Low |
| Temperature Range | -40°C to +120°C | -40°C to +100°C | -50°C to +200°C |
| Weather Resistance | Excellent | Excellent | Excellent |
| UV Resistance | Good | Good | Excellent |
| Cost | Moderate | Moderate | High |
The table shows that EPDM is a popular choice for its balance of performance and cost. Silicone offers superior temperature and UV resistance but comes at a higher price. The choice depends on the specific application and environmental conditions. Companies such as www.extrusionrubber.com offer a range of materials to suit different needs.
Types of Window Rubber Seals
Window rubber seals come in various shapes and designs to accommodate different window and door types. The selection depends on the specific application and installation method. Hebei Shida Seal Group Co., Ltd. (www.shidarubber.com) highlights their diverse product line.
| Type | Description | Applications | Advantages | Disadvantages |
