Typical usage ratio

• 70–95% of the encapsulant layer formulation, adjustable for panel thickness and expected UV exposure; additional ratios depend on required mechanical strength and lamination speed.

Downstream process integration

• Sheet extrusion followed by lamination and cross-linking during module assembly; integration at the encapsulation stage before glass back sheet application.

Final product types

• Crystalline silicon photovoltaic modules
• Bifacial solar panels
• Flexible solar modules for building-integrated photovoltaics (BIPV)

2. Hot-Melt Adhesives for Packaging and Bookbinding

Typical usage ratio

• 30–60% of the total compound, depending on required mechanical performance, flame retardancy, and flexibility for specific cable grades and diameters.

Downstream process integration

• Melt blended with fillers, plasticizers, and stabilizers in compounding extruders; applied during wire extrusion as primary insulation or jacketing layers.

Final product types

• Low-voltage power distribution cables
• Automotive wire harnesses
• Telecommunications signal cables
• Flexible appliance cords

4. Footwear Injection Molding Compounds

Footwear manufacturers require resilient, cushioning midsoles and outsoles for both athletic and leisure shoes. EVA delivers high rebound properties, impact absorption, and low weight, enabling downstream processors to produce varied foam densities via injection or compression molding technologies without sacrificing comfort or durability.

Industry compliance standards

• ISO 20344 (Personal protective equipment – test methods for footwear materials)

• GB/T 15107 (China national footwear standard)

Typical usage ratio

• 60–100% of the foamed shoe compound, adapted with blowing agents and additives to achieve specific densities and resilience based on the application type.

Downstream process integration

• Directly foamed and injected as midsoles or soles; optionally blended for co-molding with rubber or thermoplastic PU in multi-stage molding lines.

Final product types

• Sports shoe midsoles
• Children’s foam sandals
• Casual slipper outsoles
• Work safety boot components

5. Film Casting for Flexible Packaging

Flexible packaging firms leverage EVA’s sealing performance, toughness, and transparency in multilayer films for food and consumer goods. By acting as the sealing or adhesion-promoting layer, this material enables converters to produce films capable of high-speed packaging, deep freeze applications, and peelable lid structures without compromising clarity or shelf life.

Industry compliance standards

• FDA 21 CFR 177.1350 (Ethylene-vinyl acetate copolymers – food contact approval)

• 5–20% in multilayer film structures, adjusted for required sealing strength, heat resistance, and peel characteristics by packaging form and filling process.

Downstream process integration

• Co-extruded as inner or tie layer; cast or blown film extrusion before slitting, printing, and pouch forming at converter facilities.

Final product types

• Vacuum food bags
• Peelable lidding films
• Frozen food pouches
• Laminated snack wraps

6. Masterbatch Carriers for Pigments and Additives

Masterbatch and color concentrate producers require a universal carrier resin to facilitate pigment dispersion without agglomeration and with high process stability.
