• UL 1703 (Standard for Flat-Plate Photovoltaic Modules)
• RoHS 2011/65/EU (Restriction of Hazardous Substances)

Typical usage ratio

• Used at 70–85% by weight in film formulation; filler loading, crosslinkers, and stabilizers adjust per encapsulant specification, cell architecture, and desired crosslink density.

Downstream process integration

• Feeds directly into single- or multi-layer extrusion and blown film lines, then proceeds to lamination with PV cells using vacuum laminators at 140–155°C, followed by curing to fix the encapsulant.

Final product types

• PV encapsulant films for solar panels (mono/polycrystalline modules, thin-film modules, bifacial modules, and building-integrated photovoltaics).

2. Footwear Injection Molding Compounds

Footwear manufacturers select V5110F EVA as the core polymer for producing midsole foam, outsole sheets, and slip-resistant pads. This grade supports direct injection processes and physical foaming methods, yielding flexible, lightweight, and compression-set-resistant products. Operators achieve fine cell structure and consistent rebound performance, essential for athletic, safety, and children’s shoes. Integration with pigments, crosslinkers, and processing aids enables color fidelity and dimensional control in finished footwear components.

Industry compliance standards

• REACH Regulation (EC) No 1907/2006 (Chemical Substance Registration)
• GB/T 15107 (Chinese Standard for Rubber Shoes)

• CPSIA for Children’s Footwear (U.S. Consumer Product Safety Improvement Act)

Typical usage ratio

• In foam midsole blends, EVA comprises 60–85% by weight; modifiers and fillers added as per hardness, foaming rate, and color retention required by design and athletic application.

Downstream process integration

• Processed via melt mixing, then injected or compression molded under 140–180°C; physical blowing agents can be dosed for expansion, with in-mold crosslinking as required for structural footwear parts.

Final product types

• Sports shoe midsoles, sandal bases, occupational outsole pads, foam insert sheets, and children’s EVA sandals.

3. Hot Melt Adhesive (HMA) Formulations

Adhesive compounders use this EVA as a primary polymer in hot melt adhesive recipes, targeting packaging, woodworking, and hygiene disposable industries. The copolymer’s melt flow and compatibility with tackifiers enable custom viscosity and bond strength adjustment. The material facilitates rapid cooling and cohesive strength for carton sealing, bookbinding, and filter assembly. Downstream integrators focus on balancing processing open time and setting characteristics, critical for automated and high-throughput gluing applications.

Industry compliance standards

• FDA 21 CFR 175.105 (Adhesives for Food Packaging)
• ISO 9001:2015 (Quality Management for Adhesives Manufacturing)
• ASTM D1876 (Peel Resistance Testing)
• EN 923 (Adhesives – Terminology and Classification)

Typical usage ratio

• Ranges from 40–60% by weight as adhesive base; further formulated with 25–40% tackifier resins, plasticizers, and additives depending on substrate and end-use temperature requirements.

Downstream process integration

• Compounders blend the resin into heated reactors, then granulate or pelletize; end users feed granules into tank melters or slot coaters, apply in molten state (120–180°C) to substrates, followed by compression or roll assembly.

Final product types

• Hot melt adhesives for carton closing, furniture edge banding, disposable diaper assembly, book spine gluing, and filter pleat bonding.

4. Wire and Cable Polymeric Sheath Compounds

Wire and cable manufacturers employ this EVA as a base polymer in insulation and jacketing compositions where flame retardancy, flexibility, and chemical resistance must be balanced. Compounds using this grade ensure extrudability for low smoke, halogen-free sheaths, supporting indoor energy cables, signal wires, and data cable applications. The polymer controls dielectric properties and elongation at break, meeting critical safety and mechanical standards in the electrical sector.

Industry compliance standards

• IEC 60332-1/IEC 60332-3 (Flame Propagation Tests)
• RoHS 2011/65/EU (Limits for Substances in Electrical Equipment)
• EN 50267-2-1 (Corrosive Gas Emission Test)
• UL 1581 (Reference Standard for Electrical Wires, Cables, and Flexible Cords)

Typical usage ratio

• Forms 35–60% of total compound; loading varies based on hardness target and whether blending with polyolefins or further flame retardants such as ATH (aluminum trihydrate).

Downstream process integration

• Incorporated into internal mixers or twin-screw extruders with flame retardant fillers; extruded onto wire conductors at 150–180°C, calibrated, and cooled for solidification and surface finish control.

Final product types

• Low smoke, halogen-free (LSHF) wire insulation, data cable sheathing, indoor building wire jackets, and specialty electronic wire coatings.

5. Injection Foam Toys and Novelty Goods

Toy and recreational goods manufacturers select this copolymer to produce lightweight, safe, and colorful foam-based products. The EVA structure ensures non-toxic formulation, flexibility, and impact resistance for items including toy blocks, mats, and water play goods.
