Applications of Hyundai VA900 EVA in Industrial Manufacturing

Hyundai VA900 EVA (ethylene-vinyl acetate copolymer) enables precise formulation and process control for demanding downstream sectors. As direct manufacturers, we support high-spec industries with application data, technical integration guidance, and reliable sourcing for continuous, large-scale operations.

1. Solar Photovoltaic Encapsulation Films

Solar module producers use VA900 EVA to create encapsulant layers protecting photovoltaic cells against moisture, dust, and electrical degradation. This grade ensures consistent crosslinking and optical transmission in lamination, matching power output retention and module longevity. Producers optimize film extrusion and lamination parameters to meet global certification for module reliability and climate durability.

• ISO 9001:2015 (Quality management systems for continuous production)

Typical usage ratio

• Encapsulant film production: 60–80% VA900 EVA in film formulation by weight, balance with UV stabilizers and crosslinking agents. Adjust proportion based on film thickness and die design.

Downstream process integration

• Direct extrusion and calendaring of films, pellet blending with formulation additives, hot-melt lamination onto cell strings, crosslinking during module autoclave or vacuum lamination.

Final product types

• Monocrystalline PV modules
• Polycrystalline solar panels
• Flexible thin-film solar laminates
• BIPV (building-integrated photovoltaic) glass panels

2. Hot Melt Adhesive Formulations

Packaging, woodworking, and hygiene product plants use VA900 EVA as a primary hot melt polymer, targeting controlled tack, setting time, and cohesive strength. Manufacturers select vinyl acetate content and melt flow grades by end-use adhesive performance and production speed. Melt compounding occurs with tackifiers, resins, and antioxidant additives to ensure specification targets in continuous glue application.

Industry compliance standards

• FDA 21 CFR 175.105 (Adhesives for indirect food contact, US market)
• EN 923 (Adhesives – terms and definitions for technical documentation)
• ISO 9001:2015/ISO 14001:2015 (Quality/environment for adhesives production sites)
• SOLAS/EN 204 (Adhesive performance for timber processing)

Typical usage ratio

• Hot melt adhesive core formulation: 25–60% VA900 EVA, depending on required viscosity, open time, and adhesion profile. Higher ratios for flexible, lower-melt adhesives; reduced percentage in highly filled, rigid systems.

Downstream process integration

• Batch or continuous compounding with resins, process oil, and performance additives. Direct extrusion or pelletizing into hot melt sticks, pillows, or blocks. Final product loaded into hot melt tanks for automated application, spray, bead, or slot-die methods.

Final product types

• Hygiene article adhesives (diaper, sanitary pad assembly)
• Bookbinding hot melts
• Corrugated packaging sealants
• Edge banding adhesives for woodworking

3. Wire and Cable Compounds

Insulation compound manufacturers use VA900 EVA as the base resin for flame-retardant, flexible sheaths in low-voltage power and coaxial cables. Blending with flame-retardant fillers and crosslinking agents, this EVA grade ensures targeted electrical, physical, and thermal properties. Downstream partners evaluate compounding rheology and extrusion stability for high-throughput wire coating lines.

Industry compliance standards

• IEC 60502-1 (Power cables with extruded insulation)
• UL 1581 (Electrical wires, cables, and flexible cords testing methods)
• RoHS 3 (2015/863/EU – Heavy metal and flame retardant restrictions)
• ISO 6722 (Road vehicle cable physical and electrical requirements)

Typical usage ratio

• Wire insulation compounding: 40–80% VA900 EVA, based on desired softness, flame-retardancy needs, and flexibility. Lower EVA for stiffer, high-filler formulations.

Downstream process integration

• Banbury or twin-screw compounding with ATH (aluminum trihydrate), stabilizers, and color masterbatch. Direct pelletizing, then melt extrusion onto copper/aluminum wire conductors using continuous vulcanization or irradiation crosslinking as required.

Final product types

• Low-voltage building cables
• Home appliance cords
• Telecom cable jacketing
• Flexible automotive wire sheaths

4. Foam Injection and Slabstock Manufacturing

Producers of sports, packaging, and automotive foams utilize VA900 EVA to achieve uniform closed-cell structure, targeted resilience, and density control in both injection and continuous slabstock lines. This grade delivers key expansion and flexibility for water-blown or chemical-blown processes, integrating within proprietary foam recipes for tuned end-use cushioning or protection characteristics.

Industry compliance standards

• EN 71-3:2019 (Safety of toys–Migration of certain elements for EVA-based toys and playground products)
• REACH (EU Regulation No. 1907/2006 for SVHC substances)
• ISO 9001:2015 (Quality management in foam production)
• RoHS (Directive 2011/65/EU for electrical packaging foams)

Typical usage ratio

• Foam compounding: 50–95% VA900 EVA, depending on product density. Blending adjusted for chemical blowing agent and filler content.

Downstream process integration

• Blending with crosslinking and foaming agents, dispersion in twin-screw extruders or mixing lines, then direct injection molding or slabstock extrusion, with post-extrusion curing or steam crosslinking steps.

Final product types

• Sports shoe midsoles and insoles
• Protective foam mats and tiles
• Case inserts and protective packaging foams
• Auto interior cushioning blocks

5. Flexible Film and Sheet Extrusion for Packaging

Food, pharmaceutical, and medical packaging manufacturers depend on VA900 EVA for high-clarity, flexible films with tailored sealability and puncture resistance. Processors precisely select VA content and copolymer architecture for low-temperature sealing, anti-blocking, and compatibility with multilayer barrier structures. Integrated QC confirms film performance for audit and certification against regulated end-use applications.
