| Feature | EPDM Rubber | PVC | Foam Rubber (e.g., Polyurethane) |
|---|---|---|---|
| Durability | Excellent | Good | Moderate |
| Weather Resistance | Excellent | Good | Good |
| Temperature Range | Wide (-40°C to 120°C+) | Moderate | Moderate |
| Flexibility | Good | Moderate | Excellent |
| Cost | Moderate to High | Low to Moderate | Low to Moderate |
| Sound Insulation | Good | Moderate | Good |
These variations influence the cost and suitability for different applications. Companies like Hebei Shida Seal Group, showcased on www.shidarubber.com, specialize in EPDM rubber compounds known for their superior properties.
Exploring Different Types of Auto Door Seal Strips
Auto door seal strips come in various shapes and designs, each suited to specific needs. Key distinctions include:
| Type | Description | Advantages | Disadvantages |
|---|---|---|---|
| Standard Extruded | Simple, continuous profile, often with a bulb or lip for sealing. | Economical, easy to install. | May not provide optimal sealing on uneven surfaces. |
| Co-extruded | Combines different materials (e.g., dense and sponge rubber) for enhanced performance. | Improved sealing, durability, and weather resistance. | More expensive than standard extruded seals. |
| Molded | Custom-shaped seals for precise fit and complex designs. | Superior sealing on irregular surfaces. | Most expensive, longer lead times. |
| Adhesive-backed | Features self-adhesive backing for easy installation. | Quick and easy installation, no additional fasteners required. | May not adhere well to all surfaces, can be less durable. |
| Clip-on | Secured using retaining clips, offering a more robust and durable installation. | Durable, secure fit, suitable for high-vibration applications. | More complex installation. |
The selection depends on the vehicle’s design, the desired level of sealing, and budget considerations. Websites such as www.rubberstripseal.com highlight a diverse range of these types.
