TPE and EPDM weatherstrips offer superior thermal insulation, reducing heat transfer and minimizing air leakage. Their closed-cell structure helps maintain consistent interior temperatures, reducing energy costs by preventing heat loss or gain, which is critical for energy-efficient building and automotive applications.
Both materials are highly effective in noise reduction, thanks to their density and elasticity. Their ability to absorb sound waves and prevent vibration transmission enhances acoustic performance, making environments quieter by blocking external noise, ideal for both automotive and construction applications.
