The formamide-removing additive is an eco-friendly functional agent specially developed for EVA, PE and XPE plastic and rubber foaming systems. It targets free formamide, ammonia gas and pungent odors generated by ADC foaming agents during high-temperature foaming. Through chemical degradation reactions, it fundamentally decomposes residual formamide, thoroughly solving industrial pain points such as excessive formamide residue, finished product stuffy odor, storage odor recurrence and formamide rebound during high-temperature transportation. Featuring strong compatibility and low dosage, the product requires no modification to existing production processes, and is applicable to both primary and secondary foaming processes. It is a professional environmental compliance additive for maternal and infant mats, yoga mats, shoe foam materials and export-oriented rubber and plastic products.
