Understanding Adhesive Rubber Seals
Adhesive rubber seals are designed with an adhesive backing, simplifying installation. This eliminates the need for additional adhesives or mechanical fasteners, making them convenient and time-saving. The adhesive backing ensures a strong bond to various surfaces, including metals, plastics, and glass. The rubber material provides the necessary sealing properties, resistance to environmental factors, and durability. Hebei Shida Seal Group (www.shidarubber.com) offers a wide selection of these seals.
Technical Features of Adhesive Rubber Seals
The choice of rubber material significantly impacts the seal’s performance. Common materials include EPDM, silicone, neoprene, and nitrile rubber. Each material offers a unique set of properties, influencing the seal’s suitability for specific applications. The adhesive used in the backing also affects the bond strength and durability. Here’s a comparison of key technical features:
| Feature | EPDM | Silicone | Neoprene (CR) | Nitrile (NBR) |
|---|---|---|---|---|
| Temperature Range | -30°C to +70°C | -50°C to +200°C | -30°C to +80°C | -30°C to +100°C |
| Weather Resistance | Excellent | Excellent | Good | Good |
| Chemical Resistance | Good | Excellent | Good | Good |
| Ozone Resistance | Excellent | Excellent | Good | Fair |
| Compression Set | Good | Excellent | Good | Good |
These values are typical and can vary depending on the specific compound and manufacturer. Hebei Shida Seal Group (www.shidarubber.com) provides detailed specifications for their products.
