Final product types

• Sealing adhesives for food and beverage cartons
• Spine glue for perfect bound books
• Case and carton sealing compounds
• Label and envelope adhesives

2. Polymer Modification for Cable Compounding

Wire and cable manufacturers select V7470M for modifying insulation and sheathing compounds due to its balance of flexibility, low temperature performance, and electrical insulation properties. Utility and power cable producers require high molecular weight EVA copolymers to improve extrudability and abrasion resistance in demanding environments, such as underground or automotive harness applications, without compromising flame retardancy or process stability.

Final product types

• PV encapsulant sheets for solar panel assembly
• Backsheet intermediate composites
• Photovoltaic module protection films

4. Foam Shoe Soles and Sports Goods Molding

Footwear and sports equipment manufacturers use our EVA copolymer to achieve the resilient, lightweight cell structure prized in athletic shoe soles and protective gear. Molders gain fine control of expansion, density, and shock absorbance, which is critical in meeting both international performance and occupational safety requirements. The resin produces consistent foam morphology in injection and compression processes, minimizing shrinkage and supporting complex mold designs for specialty uses like track shoes or safety clogs.

Industry compliance standards

• ISO 20344/20345 (Personal protective footwear)

• Incorporated in bulk mixing with blowing agents and colorants, followed by foaming in compression or injection molds at defined temperature and pressure profiles

Final product types

• EVA foam midsoles for running and training shoes
• Injection-molded sandals and safety clogs
• Shock-absorbing padding for helmets, shin guards
• Gym flooring tiles and yoga mats

5. Film Extrusion for Agricultural and Horticultural Coverings

Producers of plastic films for greenhouses and crop protection turn to this EVA grade to enhance weatherability, softness, and light transmission in multiseason applications. The copolymer resin provides improved resistance to cracking and shrinkage under sun and temperature cycling, supporting the durability requirements of intensive agricultural operations. Modified EVA films enable precise control of diffusion and filtration properties for light management in the field.
