Technical Features of Sealing Rubber Strips
The performance of sealing rubber strips is determined by several key technical features. These features vary depending on the material and intended application. The table below highlights some of the most important considerations. Manufacturers such as HCsealstrip.com carefully consider these factors during production.
| Feature | Description | Importance |
|---|---|---|
| Material | EPDM, Silicone, PVC, Neoprene, etc. Each material offers unique properties. | Determines chemical resistance, temperature range, weatherability, and durability. |
| Hardness (Shore A) | Measures the material’s resistance to indentation. Ranges from 0 to 100. | Affects the strip’s compression set and ability to conform to irregular surfaces. |
| Tensile Strength | Resistance to being pulled apart. | Crucial for maintaining seal integrity under stress. |
| Elongation | Percentage of stretch before breaking. | Indicates flexibility and ability to accommodate movement or expansion/contraction. |
| Compression Set | Permanent deformation after compression. | Important for maintaining a consistent seal over time. |
| Temperature Range | Operating temperature limits. | Determines suitability for specific environments. |
| Chemical Resistance | Ability to withstand exposure to various chemicals. | Essential for applications involving corrosive substances. |
Types of Sealing Rubber Strips
Sealing rubber strips come in various shapes and configurations, each designed for specific applications. The choice depends on the gap to be sealed, the required performance characteristics, and the environmental conditions. Kaxite Sealing (www.seal-china.com) and Weixian Yatai Seals Co., Ltd. (www.yataisealing.com) offer diverse options.
| Type | Shape | Applications | Advantages | Disadvantages |
|---|---|---|---|---|
| D-Shaped | D-shaped profile | Doors, windows, automotive applications | Easy to install, effective sealing | Limited to specific gap sizes |
| U-Shaped | U-shaped profile | Doors, windows, weather stripping | Simple design, good compression | May not be suitable for large gaps |
| EPDM Sponge | Rectangular, various profiles | Doors, windows, automotive, industrial applications | Excellent weather resistance, good compression, insulation properties | Lower tensile strength than solid EPDM |
| Solid EPDM | Rectangular, various profiles | Automotive, industrial applications requiring high durability and strength | High tensile strength, excellent chemical resistance, long lifespan | Less flexible than sponge EPDM |
| Silicone | Various profiles | High-temperature applications, demanding sealing requirements | Wide temperature range, excellent flexibility, good chemical resistance | Can be more expensive than other materials |
| PVC | Various profiles | General-purpose sealing, less demanding applications | Cost-effective, easy to work with | Lower temperature resistance, less durable than rubber materials |
| Pile Weatherstrip | Bristle-like profile | Doors, windows, improving energy efficiency | Excellent sealing, sound and thermal insulation | Can be more difficult to install, requires more maintenance |
Applications
Sealing rubber strips are widely utilized across numerous sectors. Their versatility makes them indispensable in many applications. The specific type of rubber strip chosen depends heavily on the application’s requirements.
Conclusion
The Chinese sealing rubber strip industry is a significant contributor to the global market. The wide range of materials, designs, and manufacturing capabilities ensures that there’s a suitable solution for almost every application.

FAQs
1. What is the most common material used for sealing rubber strips in China?
EPDM (ethylene propylene diene monomer) is widely used due to its excellent weather resistance, ozone resistance, and durability.
2. How do I choose the right hardness for my sealing rubber strip?
The ideal Shore A hardness depends on the application. Softer strips (lower Shore A) conform better to uneven surfaces but may compress more. Harder strips (higher Shore A) maintain their shape better but may be less flexible.
3. What are the advantages of using EPDM rubber strips?
EPDM offers excellent weather resistance, ozone resistance, and chemical resistance. It’s durable and has a long lifespan, making it ideal for outdoor and demanding applications.
4. What is the difference between solid and sponge EPDM rubber strips?
Solid EPDM is denser and stronger, providing better durability and resistance to wear. Sponge EPDM is more flexible and provides better insulation and compression sealing.
5. Where can I find reliable suppliers of sealing rubber strips in China?
Many reputable manufacturers operate in China. Online directories, trade shows, and direct contact with factories are ways to find reliable suppliers.
