Typical usage ratio

• 18–35% (by weight in cable compound), adjusted based on flame retardancy, mechanical flexibility, or crosslinking requirements

Downstream process integration

• Extruded into masterbatch alongside polyolefin base, co-extruded with flame retardants and stabilizer package in cable compounding stage

Final product types

• Cross-linked polyethylene (XLPE) insulated power cables
• Automotive battery cables
• Telecommunications and signal transmission wires
• Flexible data cable sheathing

2. Hot Melt Adhesive Formulations

The formulation of hot melt adhesives in both packaging and bookbinding relies on the low-temperature flexibility and compatibility that our EVA provides. Production lines incorporate the resin to achieve controllable viscosity and set times, allowing high-speed applications and secure bonding of varied substrates such as paper, foil, and certain plastics.

Industry compliance standards

• FDA 21 CFR 175.105 (Adhesives for indirect food contact in the US market)
• EU Regulation (EC) No 1935/2004 on Materials Intended to Come into Contact with Food

• ASTM D1876 (Standard Test Method for Peel Resistance of Adhesives)

Typical usage ratio

• 28–42% in adhesive blend, varying with target setting speed and tack; higher percentages for flexible packaging, lower for rigid substrates

Downstream process integration

• Fed as a primary polymer component into compounding reactors with tackifiers, waxes, and antioxidant packages; pelletized before melt application in high-speed coating equipment

Final product types

• Food carton sealing adhesives
• Spine adhesives for softcover books
• Pressure-sensitive tapes and labels
• Woodworking assembly glues

3. Film Extrusion for Flexible Packaging

This grade is a preferred component in flexible food and non-food packaging films, primarily where puncture resistance and seal integrity are critical. Film extrusion converters blend the EVA into multilayer recipes to optimize heat sealing response, clarity, and mechanical toughness for finished packaging rolls and bags.

Industry compliance standards

• FDA 21 CFR 177.1350 (Ethylene-vinyl acetate copolymer for food packaging)
• BfR Recommendation XXI (German Federal Institute for Risk Assessment for food-contact polymers)
• GMP Regulation (EU) No 2023/2006 for Good Manufacturing Practice in food contact materials
• EN 12301 (European standard for control of film seals)

Typical usage ratio

• 8–20% of core or sealant layer; proportion adjusted for required seal strength versus flexibility, often higher in stand-up pouch applications

Downstream process integration

• Incorporated via gravimetric feeders into blown or cast film co-extruders, produced in multi-layer (3–7 layer) structures targeting specific sealing or barrier properties

Final product types

• Retort pouch inner films
• Vacuum bag sealant layers
• Frozen food packaging films
• Medical device packaging with peelable seals

4. Solar Panel Encapsulant Sheets

EVA copolymers constitute a key ingredient in the encapsulant films that protect photovoltaic (PV) cells against moisture and environmental exposure. Sheet producers rely on our grade for its transparency and resistance to crosslinking under lamination, ensuring high light transmittance and long operational panel life.

Industry compliance standards

• IEC 61215 (Performance qualification for crystalline silicon PV modules)
• UL 1703 (Standard for Safety: Flat-Plate Photovoltaic Modules and Panels)
• EN ISO 4892-2 (Accelerated aging testing for plastics)
• RoHS compliance for heavy metals and regulated substances

Typical usage ratio

• 92–98% of encapsulant sheet composition, with small proportions of crosslinking promoter, UV absorber, and antioxidant

Downstream process integration

• Mixed with cross-linking initiators and additives; extruded into sheets (typically 0.4–0.6 mm thick); laminated in situ onto PV cell arrays during module assembly

Final product types

• Monocrystalline and polycrystalline PV panel encapsulant films
• Bifacial solar module encapsulation layers
• Building-integrated photovoltaic panel sheets

5. Foam Sheet Manufacturing

Manufacturers producing foam sheets for sports, construction, and footwear industries depend on our EVA to impart softness, elasticity, and cell stability. The resin performs as the primary matrix component, supporting uniform foam expansion and rebound characteristics in both physical and chemical foaming systems.

Industry compliance standards

• ISO 846:2019 (Evaluation of plastics for microbial resistance in open environments)
• Oeko-Tex Standard 100 (Textile and footwear applications—restrictions on harmful substances)

• ASTM D3575 (Testing of flexible cellular materials—open-cell and closed-cell plastic foams)

Typical usage ratio

• 40–85% of the foam composition, adjusted for degree of softness, thickness, and foaming gas/loading filler systems

Downstream process integration

• Dry blended with blowing agents and fillers, then processed via continuous sheet extrusion with in-line expansion or via compression-molding for thicker foam blocks

Final product types

• Sports mat rolls and tiles
• Construction underlay foams
• Footwear insoles and midsoles
• Protective packaging foams

6. Injection Molding for Sports and Leisure Goods
