The fast setting agent uses polymers such as high-crystallization long-chain nylon with appropriate carbon chain length to compound with EVA, and uses a special process to form a blend of micro-nano-scale fibers and polymer elastomers. This product mainly solves the industry problem of long setting time for EVA secondary molded foam products, and significantly shortens the product molding cycle.

Introducing KD-600H Fast Setting Agent – an advanced polymer-based additive designed to significantly accelerate the secondary molding process of EVA foam products. This innovative agent is formulated with high-crystallization long-chain nylon and compounded with EVA through a specialized micro-nano fiber blending technology. It effectively addresses the industry challenge of prolonged setting times, enabling manufacturers to enhance production efficiency without compromising material integrity.
KD-600H offers exceptional fast-setting properties, reducing secondary molding time by 20–25%. It also acts as a nucleating agent, resulting in finer and more uniform cell structures, which improve the overall aesthetic and functional quality of foam products. Importantly, it maintains all original physical properties of the EVA formulation, ensuring consistent performance and reliability.
Key Advantages
Accelerates molding process and increases production output
Enhances cell structure for superior product finish
No adverse effect on mechanical properties of EVA
Easy to use and integrate into existing production lines
Application Areas
EVA midsole production for footwear
Sports equipment padding
Automotive interior foam components
Packaging cushioning materials
Yoga mats and fitness foam products
Child play mats and foam toys
