The ceramic rubber cap is a specialized sealing and protection product designed for battery pack apertures. Its core feature is a unique high-temperature response capability—when exposed to elevated temperatures, it gradually hardens, forming a more robust structure while retaining its protective function. This ceramification process ensures the rubber plug remains effective even in extreme conditions, enhancing overall safety and durability.

Crafted from advanced ceramifiable rubber material, the product combines flexibility and heat resistance. Under normal conditions, it remains soft and deformable, facilitating easy installation and secure adaptation to apertures of varying sizes. However, when temperatures rise—such as during overheating or fire incidents—the rubber plug begins to harden, forming a heat-resistant barrier that effectively shields internal components from damage and maintains structural integrity.

This intelligent thermal-responsive property makes the product particularly suitable for electric vehicles, energy storage systems, and other applications demanding high battery safety standards.
