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.

KD-500L Fast Setting Agent is an advanced polymer-based additive specifically designed for EVA (ethylene-vinyl acetate) secondary compression molding processes. It is composed of high-crystallization long-chain nylon and EVA composite, engineered through a special micro-nano fiber blending technology. This product significantly reduces the setting time of EVA foam products by 15–20%, enhances cell structure uniformity through nucleation, and improves production efficiency without compromising the physical properties of the original formulation.
Ideal for footwear midsole production, sports equipment, packaging materials, and other EVA foam applications, KD-500L ensures finer cells, better product consistency, and shorter cycle times. It is easy to use, with a recommended dosage of 3–5%, and complies with industry standards for safety and performance.
Store in a cool, dry place away from direct sunlight and heat sources. Available in 25kg bags or cartons.
Application Fields
Footwear midsoles
Sports and leisure products
EVA foam padding and insulation
Packaging materials
Automotive interior components
Yoga mats and fitness equipment

Appearance
White granule
Advantages
Secondary compression molding time is shortened by 15–20%
Has nucleation effect, and the cells are finer
Does not affect the physical properties of the original formula
Recommended for use in EVA midsale secondary compression foaming process.
Package Storage
It must be stored in a cool, dry place, and kept away from hot steam pipes and fire sources to avoid direct sunlight. This auxiliary is packed by 25kg per bag or carton.
Reference Dosage
3–5%
