One solution adopts full‑polyester system: shell A‑2100/B‑3020 matching inner filling A‑2160PJ/B‑6323. Shell hardness ranges 60‑70 C, inner filling hardness 45‑65 C. It features low overall density, outstanding wear resistance and reliable anti‑slip property, suitable for casual shoes and safety‑footwear outsoles.
The second is polyester‑polyether combined solution: polyester‑based shell A‑2100/B‑3020 paired with polyether inner filling A‑1112/B‑5003‑1. The outer shell maintains good abrasion and slip performance; the polyether inner core brings high elasticity with ball rebound above 55 %, inner filling hardness 35‑45 C. This hybrid formula targets sports‑style footwear requiring both surface durability and soft cushioning.
Both material lines produce defect‑free surfaces free of bubbles. No post‑spray painting is required, helping factories shorten production chains and reduce auxiliary‑material consumption. Compared with conventional casting crafts, spray‑PU technology simplifies workflow, reduces manual dependence and unlocks more possibilities for complicated shoe‑body design.
