Applications of Mitsui Chemicals Evaflex EV210 EVA in Industrial Manufacturing

Evaflex EV210 EVA from Mitsui Chemicals is widely recognized for its consistent performance and outstanding processability across critical industrial manufacturing segments. Below, we detail the key downstream application scenarios, each mapped to specific compliance requirements, precise formulation guidance, defined integration points, and end use product categories.

1. Photovoltaic Module Encapsulation

This grade is widely adopted as the primary encapsulant resin for solar panel production lines, thanks to its reliable crosslinking behavior and UV stability. Formulators calibrate the melt flow and vinyl acetate content to match stringent long-term weathering and lamination standards. Process engineers add the resin during the film extrusion phase, which determines cell adhesion, transparency, and delamination resistance in the final module stack.

Industry compliance standards

• IEC 61215 (Crystalline silicon terrestrial photovoltaic modules)
• IEC 61730 (PV module safety qualification)
• UL 1703 (Flat-plate PV panels and modules)
• RoHS Directive 2011/65/EU (Restriction of Hazardous Substances)

Typical usage ratio

• 65–75% of total encapsulant film weight, adjusted per layer thickness and module architecture

Downstream process integration

• Compounded with crosslinking and UV stabilizer masterbatches, then extruded into film for vacuum lamination over solar cells

Final product types

• Monocrystalline silicon PV modules
• Polycrystalline silicon PV panels
• Flexible solar modules

2. Hot Melt Adhesives for Packaging and Hygiene Products

EVA copolymer resins deliver strong tack, flexibility, and melt processability in industrial hot melt adhesive formulas. Adhesive compounders rely on this grade to balance open time and setting speed for high-throughput case sealing or disposable hygiene product production, adjusting the addition level depending on bonding target surfaces and final melt viscosity needs. The resin enters mixer compounding lines during the hot melt formulation stage before granulation or block molding.

Industry compliance standards

• FDA 21 CFR 175.105 (Adhesives for food packaging contact)
• EN 13432 (Compostability, when used in biodegradable applications)
• ISO 9001 (Quality management in production)

Typical usage ratio

• 20–45% by weight of the adhesive blend, determined by required tack, flexibility, and melt flow

Downstream process integration

• Incorporation during melt mixer blending with tackifiers, waxes, and stabilizers; followed by pelletizing, block casting, or direct application in hot melt coaters

Final product types

• Case and carton sealing adhesives
• Feminine hygiene pad and baby diaper construction adhesives
• Labels and pressure-sensitive adhesive tapes

3. Cable and Wire Insulation Compounds

Industrial cable coating companies formulate EVA-based insulation to realize the required flexibility, dielectric properties, and flame retardancy for power and communication cables. Production formulates accurate proportions of flame retardants and antioxidant packages with this grade prior to compounding and extrusion. Regulatory compliance drives composition, especially for electrical safety and hazardous substance restrictions in finished goods.

Industry compliance standards

• IEC 60502 (Power cables with extruded insulation)
• UL 1581 (Reference standard for electrical wires, cables, and flexible cords)
• RoHS Directive 2011/65/EU
• REACH Regulation (EC) No 1907/2006

Typical usage ratio

• 30–60% by total cable compound, varying with flame retardant loading and mechanical targets

Downstream process integration

• Dosed in internal mixers or twin-screw compounders with fillers, FR, pigments, then processed via continuous extrusion into cable sheaths or insulation layers

Final product types

• Low voltage power cables
• Telecommunication wires
• Data and fiber optic cable insulation coverings

4. Footwear Foam Injection Molding

Shoe manufacturers use this EVA grade as the elastomeric base for injection molded midsole and outsole foams, balancing cushioning with durability requirements set by global brands. Engineers select the resin’s vinyl acetate content and melt index to achieve fine foam cell structure, ensuring product compliance with safety and consumer goods regulations. Material feeding takes place in the compounding section before injection or compression molding, adding blowing agents and performance modifiers as specified by footwear process protocols.

Industry compliance standards

• EN ISO 20344 (Footwear test methods)
• REACH Regulation (EC) No 1907/2006
• CPSIA (Consumer Product Safety Improvement Act, for children’s footwear)

Typical usage ratio

• 60–85% by weight in foaming compound, adjusted based on targeted hardness and resilience

Downstream process integration

• Blended in internal mixers with crosslinking agents, fillers, colorants, then directly delivered to injection or compression molding systems for expansion and forming

Final product types

• Sports shoe midsoles and outsoles
• Beach sandals and flip-flops
• Comfort insoles and shoe inserts

5. Flexible Film for Agricultural and Industrial Use

EVA serves as a co-polymeric modifier in blown or cast film formulations for greenhouses, mulching, and flexible packaging, providing controlled light transmission, mechanical tear resistance, and flexibility even at low temperature conditions. Film manufacturers optimize the addition level according to the dimensional and optical targets specified by each use, with compliance frameworks focusing on environmental and food contact safety. Addition occurs during dry blending before extrusion and film blowing or casting.

Industry compliance standards

• EN 13206 (Plastic films for agricultural use)
• FDA 21 CFR 177.1350 (Ethylene-vinyl acetate copolymers in food contact film)
• ISO 22000 (Food safety management, when used for food wraps or covers)

Typical usage ratio

• 6–25% by weight in film formulation; adjusted per light transmission, mechanical, and thickness requirements

Downstream process integration

• Dry blended with LDPE, UV absorbers, and stabilizers, then fed into extruder hoppers for blown film or cast film production

Final product types

• Greenhouse covering films
• Silage and mulch films
• Flexible food packaging films
