How often does the train EPDM sealant strip change

The function of the train EPDM sealant strip is to prevent water from entering the vehicle and improve the sound insulation performance. The sealant strip is a rubber product, which will be aged after long-term use, so it needs to be replaced regularly. The replacement time depends on the situation. Generally, the sealing strip should be replaced in three to four years.

First, check whether the sealing strip has large crack and fracture. If the sealing strip is broken, it can be repaired with adhesive. In particular, the use of special adhesive for sealing strips can easily repair large cracks. Of course, if the sealing strip is seriously damaged or aging, it is better to replace it with a new one.

The train EPDM sealant strip is mainly made of EPDM rubber foam and dense composite with good elasticity and compression deformation resistance, aging resistance, ozone and chemical action, and a wide temperature range of - 40 ° C to - 120 ° C. It contains a unique metal clamp and tongue buckle, which is durable and convenient for installation.
