A Comprehensive Guide to Window Rubbers in China
Window rubbers, also known as window seals or glazing seals, are essential components in various applications, from automotive vehicles to buildings and industrial machinery. China is a significant manufacturer and exporter of these products, offering a wide range of options to meet diverse needs. This guide delves into the world of Chinese-made window rubbers, providing insights into their technical features, different types, and key considerations.
The primary material used in Chinese window rubbers is EPDM (Ethylene Propylene Diene Monomer) rubber. EPDM is favored for its excellent weather resistance, ozone resistance, and durability. This makes it ideal for outdoor applications and ensures a long lifespan for the window seals. Other materials, such as NBR (Nitrile Butadiene Rubber), are also used, particularly when oil resistance is required. Companies like Hebei Shida Seal Group (www.shidarubber.com and www.shidaprofile.com) are prominent players in the EPDM rubber sealing profile market, showcasing their state-of-the-art equipment and manufacturing capabilities.
Technical Features of Window Rubbers
The performance of window rubbers hinges on several key technical features. These features vary depending on the specific application and material used. The following table compares some crucial aspects:
| Feature | EPDM | NBR | PVC |
|---|---|---|---|
| Weather Resistance | Excellent | Good | Good (depending on formulation) |
| Oil Resistance | Good | Excellent | Poor |
| Temperature Range | -40°C to +100°C | -30°C to +80°C (varies with formulation) | -10°C to +60°C (varies with formulation) |
| Hardness (Shore A) | 50-70 (variable) | 50-70 (variable) | 60-80 (variable) |
| Flexibility | Good | Good | Moderate to Low (depending on formulation) |
| Cost | Moderate | Higher | Lower |
