High - Durability Resilient Anti - Abrasion Car Window Lift Rubber Strips for Long - Lasting Use

The car window lift rubber strip mainly serves two key functions. Firstly, it provides a weather - tight seal. It prevents rain, dust, and wind from entering the vehicle's interior, keeping the cabin clean and dry. Secondly, it acts as a buffer between the moving window glass and the window frame. This helps to reduce noise during the window - lifting operation and protects the window glass and frame from scratches and abrasions.

There are several tell - tale signs. If you notice water leaking into the car when it rains, especially around the window edges, it's a strong indication that the rubber strip has deteriorated. 

Typically, materials such as EPDM (Ethylene - Propylene - Diene Monomer), PVC (Polyvinyl Chloride), and silicone are used. EPDM is highly resistant to weathering, ozone, and aging, making it a popular choice for long - lasting performance. PVC is cost - effective and offers good flexibility. Silicone rubber is known for its excellent heat resistance and ability to maintain its shape and flexibility over a wide temperature range. The choice of material often depends on the vehicle manufacturer's requirements and the intended application.
