Final product types

• Encapsulant interlayer films for c-Si PV modules
• Bifacial glass-glass module encapsulants
• Flexible solar panels (thin-film and specialty photovoltaic)
• PERC and TOPCon panel encapsulation layers

3. Wire & Cable Insulation and Sheathing

Cable manufacturers apply this EVA copolymer in thermoplastic and crosslinked formulations for primary insulation and jacket layers, where its melting flow properties permit continuous coating, while vinyl acetate content bestows electrical insulation and anti-cracking benefits in both low- and high-tension electrical cables.

Industry compliance standards

• IEC 60502 (Power cables with extruded insulation and their accessories)
• RoHS Directive 2011/65/EU
• EN 50363 (Insulating, sheathing and covering materials)

Typical usage ratio

• 35–70% in insulation compound; loading rate is determined by flame-retardant filler incorporation, required flexibility, and voltage rating

Downstream process integration

• Compound blending and extrusion over copper or aluminum wires in tandem with initiators or flame-retardant additives, followed by irradiation crosslinking when specified on production lines

Final product types

• Building wire insulation and jacketing
• Power and control cable sheathing
• Automotive battery cables
• Halogen-free flame–retardant (HFFR) cables

4. Flexible Footwear Sole Compounds

Shoe component compounders and footwear manufacturers rely on this material to produce durable, lightweight, and resilient foamed and solid soling grades, balancing shock absorption, processability, and surface smoothness for sportswear, leisure, and safety footwear.

Industry compliance standards

• ISO 20871 (Footwear – Outsoles – Test methods for abrasion resistance)
• REACH compliance (Annex XVII - Phthalate and PAH restrictions)
• CPSIA requirements (for US markets – heavy metal content)
• EN 20345 (Personal protective – Safety footwear)

Typical usage ratio

• 25–60% in outsole and midsole EVA foam formulations, based on hardness, foam density, and end-use comfort specifications

Downstream process integration

• Melt blending with blowing agents, colorants, and crosslinkers, then injection or compression moulding in heated metal moulds for sole shape definition and surface finish control

Final product types

• Sports sneaker outsoles and midsoles
• Sandals and flip-flop base units
• Children’s and leisure footwear soles
• Work and safety boot midsoles and outsoles

5. Film Extrusion for Agricultural and Horticultural Use

Agricultural film converters use this EVA copolymer to engineer tunnel covers, greenhouse films, and mulch layers that deliver excellent mechanical strength, low-temperature impact toughness, and controlled diffusion of sunlight and thermal radiation for crop productivity enhancement and protection.

Industry compliance standards

• EN 13206 (Plastic films for agricultural applications – Specifications and test methods)
• REACH Annex XVII (Chemical safety limits)
• ISO 9001-driven quality control in film extrusion

Typical usage ratio

• 10–35% in multilayer film blends; ratio is customized for haze, tear strength, and light transmittance, sometimes coextruded with LDPE or LLDPE

Downstream process integration

• Gravimetric blending with other polyolefins and additives, followed by blown-film or cast-film extrusion and in-line corona, anti-drip, or anti-fog treatments

Final product types

• Greenhouse covering films
• Low tunnel crop covers
• Mulching and silage films
• Thermal insulation films for horticulture

6. Masterbatch Carriers for Pigments and Additives
