EPDM rubber foaming agent

Functions of DF17 blowing agent in EPDM seals: Density reduction: Theoretically, 1-2% addition can reduce rubber density by 15-40%. The specific weight reduction effect depends on factors such as the amount added and processing conditions. Improved sound and thermal insulation: DF17 forms a uniform and stable closed-cell structure within the rubber, enhancing the product's thermal insulation, sound insulation, and insulation properties, improving surface structure, and increasing product stability. The specific improvement in thermal insulation depends on factors such as the amount added and processing conditions.
. Enhanced compression set resistance and flexural strength: DF17 offers controllable particle size and more uniform particle size distribution, effectively improving the uniformity of foam micropore diameter and distribution in the rubber, ensuring a closed-cell foam effect, thereby enhancing the rubber's compression set resistance and flexural strength.
