We offer a range of materials for different sealing applications, including EPDM, silicone, PVC, TPE, TPV, NBR, and other custom rubber or plastic compounds. The material choice depends on the required performance, such as weather resistance, temperature resistance, flexibility, compression performance, food-grade compliance, or oil resistance.
The correct sealing strip depends on several factors, including application environment, installation method, profile shape, hardness, temperature range, and required sealing performance. For example, EPDM is often used for outdoor door and window sealing, while silicone is preferred for high-temperature or food-contact applications. If you provide drawings, samples, or application details, we can recommend a suitable solution.
