What material is commonly used for door gaskets?

The most common material used for door gaskets is EPDM, which stands for Ethylene Propylene Diene Monomer. EPDM is a type of synthetic rubber known for its excellent weather resistance, UV stability, and durability, making it ideal for applications such as door gaskets in dry vans. This material can withstand extreme temperatures and varying environmental conditions, which is essential for maintaining the integrity of the seal on a freight container's doors.

In addition to its physical properties, EPDM has good chemical resistance, which contributes to longevity and performance in sealing applications. The material is also flexible, providing a reliable seal that prevents air and moisture intrusion, which is critical for protecting cargo during transport.

While the other materials mentioned have their own applications, they do not possess the same combination of weather resistance, flexibility, and durability that EPDM offers specifically for door gaskets in the transport industry.
