EPDM Seals for Refrigerated Trucks and Trailers
Sealing strips are key components in refrigerated trucks, refrigerated trailers, and cold chain transportation equipment. High-quality sealing systems effectively prevent cold air leakage, reduce the load on refrigeration units, improve energy efficiency, and ensure the quality of goods transported.
DESCRIPTION
For refrigerated truck door manufacturing, multi-lip EPDM compression sealing strips are often the more ideal choice because they offer better durability, long-term elasticity, and stable sealing performance under frequent door opening and closing conditions.
Why Choose EPDM Sealing Strips?
- Excellent thermal insulation performance.
- Good airtightness and watertightness.
- UV and ozone resistance.
- Maintains flexibility at low temperatures.
- Strong anti-aging properties.
- Easy installation and replacement.
- Suitable for frequent door opening and closing applications.
