3. Footwear Injection Moulded Soles

Shoe component suppliers use the V3110F grade in injection-moulding lines to create flexible, lightweight, and abrasion-resistant outsoles across fashion and sports footwear. The material’s vinyl acetate concentration fine-tunes elasticity and resilience, critical for cushioning and repeated flex, while process set-points are determined by cavity geometries and cooling cycles. Production must conform with industry chemical safety and physical performance tests, demanding consistent raw input and continuous monitoring.

Industry compliance standards

Typical usage ratio

• 55–70 wt% EVA in compound, adjusted for filler, colorant, and foaming agent addition; variability based on target density and hardness for the outsole grade.

Downstream process integration

• Twin-screw compounding with process oils, pigments, and blowing agents; continuous pelletizing; dry-blend loading into fully automated injection molding systems for outsole, midsole, or insole component production.

Final product types

• Direct injection-moulded shoe soles

4. Wire and Cable Sheathing Compounds

Wire and cable compounders select this EVA material as a primary base for low-smoke, halogen-free insulation and jacketing, ensuring reliable dielectric and flexural performance in energy, telecom, and building wire production. Processing lines demand precise plasticizer and fire-retardant blending to meet evolving flame retardancy and material aging regulations, as well as compatibility with pigment masterbatches for clear color-coding. The balance of processability and long-term stability is adjusted per cable specification.
