Downstream process integration

• Co-extrusion or single-layer extrusion, then integrated directly into the glazing and cell lamination step after film calendaring and pre-treatment with crosslinker masterbatch

Final product types

• Packed and rolled EVA encapsulant films for crystalline silicon and thin-film PV modules
• UV-resistant layers for bifacial solar panels

2. Hot Melt Adhesive (HMA) Production

This EVA supports hot melt adhesive compounding, delivering consistent melt flow and tack at controlled vinyl acetate content, which formulators balance with tackifiers and plasticizers to match substrates including packaging paper, wood composites, and hygiene disposables.

Typical usage ratio

• 20%–55% of the adhesive blend, adjusted for required open time and bond strength; higher ratios for pressure-sensitive adhesives, lower for fast-setting packaging grades

Downstream process integration

• Melt blending with proprietary tackifier and wax components in a sigma blade mixer or twin-screw extruder, then pelletized or formulated into glue sticks and blocks before packaging

Final product types

• Hot melt glue sticks for packaging automation
• Pressure-sensitive adhesives for hygienic closure systems
• Pre-formed adhesive pellets for woodworking or book binding equipment

3. Wire and Cable Sheathing

Cable manufacturers incorporate this EVA grade for primary sheathing and insulation extrusion, particularly where resilient flex performance, flame retardancy, and regulatory compliance for low-smoke, halogen-free (LSHF) applications are needed—such as power, telecommunication, and data cabling.

Industry compliance standards

• EN 50620 (Electric cables for photovoltaic systems with crosslinked insulation)
• IEC 60332-1, -3 (Flame-retardant performance of cables)
• RoHS compliance for hazardous substance limitation
• UL 62 for flexible cord insulation in North American markets

Typical usage ratio

• 30%–60% in masterbatch with flame retardants and crosslinking agents, fine-tuned for dielectric strength and LSHF performance according to cable diameter and spec

Downstream process integration

• Feeds into tandem extrusion lines before or after silane-grafting (for XLPE cables), or as a non-crosslinked insulation for low-voltage applications

Final product types

• Low-smoke zero-halogen (LSZH) wire insulation
• Flexible power cables for photovoltaic arrays and electronics
• Telecommunication and LAN cable jacketing

4. Foam Injection for Footwear and Sports Equipment

We supply PRIMEVA P2850M to foam compounding houses serving the shoe and sporting goods industry, as its melt index and high VA content yield controlled expansion, softness, and rebound in closed-cell foams for midsoles, yoga mats, and other sports gear. Manufacturers value this grade for its compatibility in both continuous and batch foam molding lines.

Industry compliance standards

• EN ISO 20345:2022 (Personal protective equipment – Safety footwear)
• OEKO-TEX Standard 100 (for restricted chemical substances in textiles and foams)
• ISO 6330:2012 (Textile testing for end-use resilience and washability)
• REACH Annex XVII for phthalate and plasticizer limitation in consumer goods

Typical usage ratio

• 35%–60% as the base resin in foam compounding; ratio varies based on target foam density from 0.10 to 0.30 g/cm³ and hardness/softness specification of the final part

Downstream process integration

• Dry-blending with mineral fillers, blowing agents, and pigment masterbatches, then injection or compression-molded at 120–160°C for shoes and sporting foam components

Final product types

• Injection-molded midsoles for athletic and casual shoes
• High-resilience yoga and sports mats
• Protective gear and grip pads for cycling or industrial uses

5. Flexible Packaging Film Production

Film converters use this EVA for sealing and flexibility in multilayer film composites for food, pharma, and industrial packaging. Its balance of clarity, puncture resistance, and low-seal temperature allows converters to reduce energy loads and deliver films with high sensory and barrier performance under frequent global migration and purity audits.

Industry compliance standards
