The functions achievable by DF17 foaming agent in EPDM sealing strips include reducing density: theoretically, with a 1-2% addition, the rubber density can be reduced by 15-40%. The specific weight reduction effect depends on factors such as the amount added and processing conditions. Improving sound and thermal insulation performance: DF17 forms a uniform and stable closed-cell structure within the rubber, which helps enhance the finished product's thermal insulation, sound insulation, and insulation properties, improves surface structure, and increases the stability of the finished product. The specific improvement in thermal insulation depends on factors such as the amount added and processing conditions.

Improving compression set and flex resistance: DF17 offers controllable particle size and more uniform particle size distribution, effectively enhancing the uniformity of the foam micropore diameter and distribution in the rubber, ensuring the closed-cell effect of the foam, thereby improving the rubber's compression set and flex resistance.
