Typical usage ratio

• 20–35% by weight in insulation compounds depending on flexibility, flame retardant requirement, and target application (e.g., data, power, automotive wires). Adjust for compound hardness and extrusion speed.

Downstream process integration

• Direct addition to the compounding process in banbury or twin-screw mixers, co-blended with PE or copolymer resins, followed by pelletizing and melt extrusion onto copper or aluminum conductor in wire and cable lines.

Final product types

• Low-voltage power cable insulating layers
• Telecommunication cable jackets
• Automotive primary wire insulation
• Flexible appliance wire coverings

2. Hot Melt Adhesive Formulation

Producers of industrial hot melt adhesives use this grade for its balanced melt viscosity and excellent bonding to porous and non-porous surfaces. Its consistent vinyl acetate level enhances compatibility with tackifiers, plasticizers, and waxes during formulation, providing reliable open time, tack, and cohesive strength that meet high-volume packaging and woodworking operations.

Industry compliance standards

• FDA 21 CFR 175.105 (Adhesives for indirect food contact packaging in the USA)
• REACH Regulation (EC) No 1907/2006 (EVA non-listed SVHC confirmation)
• ISO 9001:2015 (process and quality consistency for adhesive production)
• EU food contact framework regulation (EC) 1935/2004

Typical usage ratio

• 28–42% in hot melt adhesive formulations; formula adjusted for viscosity, open time, and specific performance based on end-use—carton sealing, hygiene, woodworking, or label application.

Downstream process integration

• Polymer is introduced as the primary base resin in pre-mixing kettles with tackifiers, waxes, and additives, then compounded under controlled shear, homogenized, filtered, and finally cast or pelletized for further application or packaging.

Final product types

• Case, carton, and tray sealing adhesives (packaging industry)
• Bookbinding glues
• Automotive trim bonding adhesives
• Label and tape adhesives

3. Solar Panel Encapsulation Sheets

Photovoltaic encapsulant sheet manufacturers employ this EVA grade for its high optical clarity and robust crosslinking properties. It stands up to ultraviolet aging and thermal cycling, especially after peroxide or silane-based crosslinking, ensuring low shrinkage, minimal moisture ingress, and strong interlayer adhesion demanded by international solar module performance criteria.

Industry compliance standards

• IEC 61215 (design qualification and type approval of photovoltaic modules)
• UL 1703 (standard for flat-plate photovoltaic modules in North America)
• EN 50548 (connectors and structural components for PV systems, EU)
• ISO 9001:2015 (solar packaging process quality)

Typical usage ratio

• Used as 100% base polymer for pelletizing, with 0.8–1.5 phr (per hundred resin) of crosslinking agents (such as organic peroxides) and 0.2–0.8 phr stabilizers, adjusted for desired sheet softness and cure rate.

Downstream process integration

• Material is pelletized, dry-blended with crosslinkers and UV inhibitors, extruded into films (thickness 350–500 µm), and laminated with glass and photovoltaic cells; sheets undergo hot lamination and curing during module assembly.

Final product types

• Photovoltaic module encapsulant sheets
• Backsheet interlayer films
• Building-integrated photovoltaic (BIPV) glass modules

4. Footwear Foam and Injection Molding

Footwear component manufacturers select this resin for comfort soles, midsole foams, and injection-molded sport shoe parts due to its controlled expansion characteristics and skin formation properties. The material’s processability allows precise control of hardness, rebound, and density to suit various athletic and safety footwear specifications across different regional markets.

Industry compliance standards

• EN ISO 20344/20345 (personal protective safety footwear standards)
• GB/T 15107 (China National Footwear Standards for Plastic Shoes)
• CPSIA (US Consumer Product Safety Improvement Act, heavy metal and phthalate limits)
• REACH Annex XVII (EU regulation of restricted substances)

Typical usage ratio

• 50–75% as primary copolymer in closed-cell foam formulations, blended with blowing agents, pigments, and fillers. Ratio is set based on target hardness (Shore A 35–65) and recovery performance requirements.

Downstream process integration

• This EVA enters the batch mixing phase with foaming agents (e.g., azodicarbonamide), coloring powders, and plasticizers, then passes to mold-filled extrusion, steam-press foaming, or injection-molding systems that generate finished soles or cushioning pads.

Final product types

• Sport shoe midsoles and outsoles
• Work and safety shoe soles
• Injection-molded slippers and sandals
• Cushioned insoles and pads

5. Film & Sheet for Flexible Packaging

Manufacturers of coextruded flexible packaging films adopt this EVA formulation for heat-sealable layers, especially in food-grade and medical pouch films. Its low sealing temperature paired with clarity and toughness allows downstream converters to produce reliable, contamination-resistant closures while maintaining oxygen and aroma barrier integrity in multilayer substrates.

Industry compliance standards

• FDA 21 CFR 177.1350 (EVA films for food packaging contact)
• EU Regulation (EU) 10/2011 (Polymer materials in contact with food, migration limits)

Typical usage ratio

• 10–32% in sealant layers of blown or cast film; adjusted according to the film’s mechanical strength, peelability, and sealing temperature requirements for the application (snack, medical, dairy, or vacuum packaging).

Downstream process integration

• Material is fed with LDPE or LLDPE to blown or cast film lines; forms the interior (sealing) layer in 3- to 7-layer coextruded film structures, or is laminated post-extrusion onto carriers (paper, foil, PET) before slitting and pouch-making.

Final product types

• Medical device sterilization pouches
• Dairy and snack food flexible packaging
• Vacuum and modified-atmosphere food bags
• Lidding films for trays and cups
