Technical Features of Dry Van Trailer Door Seals
The performance of a dry van trailer door seal hinges on several key technical features. These features directly impact the seal’s effectiveness in protecting cargo from environmental factors and unauthorized access. Let’s examine these crucial aspects in detail. Understanding these features helps in selecting the optimal seal for specific applications and trailer types. The quality of materials and manufacturing processes significantly influence these characteristics.
| Feature | Description | Importance |
|---|---|---|
| Material | Commonly PVC, EPDM rubber, or various foam compounds. Each offers unique properties regarding durability, flexibility, and temperature resistance. | Determines the seal’s longevity, resistance to weather, chemicals, and its ability to maintain a tight seal. |
| Durometer | Measures the hardness of the material. A higher durometer indicates a harder, more rigid seal. | Affects the seal’s compression, resilience, and ability to withstand repeated compression and expansion. |
| Compression | The amount the seal compresses when the door closes. Proper compression ensures a tight seal. | Crucial for preventing air and water leakage, maintaining temperature, and excluding dust and debris. |
| Temperature Range | The range of temperatures the seal can withstand without compromising its performance. | Essential for transporting temperature-sensitive goods. Extreme temperatures can damage unsuitable seals. |
| Seal Length/Width | Determined by the dimensions of the trailer door. Custom sizes are often available. | Ensures complete coverage and a secure seal along the entire door perimeter. |
| Installation | Methods include adhesive backing, mechanical fastening, or a combination. | Impacts ease of installation and the seal’s long-term security. |
Types of Dry Van Trailer Door Seals
The market offers various dry van trailer door seals, each designed for specific needs. The choice depends on factors like cargo type, environmental conditions, and budget. Letu Automotive, for instance, offers a wide variety of co-extruded PVC seals suitable for different applications. Understanding the distinctions between these types is crucial for informed decision-making.
| Type of Seal | Description | Advantages | Disadvantages |
|---|---|---|---|
| Rubber Gasket Seal | A continuous rubber strip that compresses against the door frame when closed. | Durable, watertight, good for moisture-sensitive goods. | Can be less flexible than other options, may require more precise installation. |
| Brush Seal | Uses bristles to create a barrier, preventing dust and debris entry. | Effective dust and debris barrier, relatively inexpensive. | Less effective against water, may not provide complete temperature control. |
| Compression Seal | Uses a compressible material to create a tight seal. | Effective at reducing air and water infiltration, good for temperature-sensitive goods. | Can wear down faster than other types, may not be as durable. |
| PVC Co-extruded Seal | Combines rigid and flexible PVC for superior sealing performance. Often used by Letu Automotive and Shida Rubber. | Excellent sealing performance, waterproof and insulation, good temperature range. | May not be as durable as rubber seals in extreme conditions. |
