Applications of Celanese Ateva 1609 EVA in Industrial Manufacturing

Celanese Ateva 1609 EVA is recognized for its high vinyl acetate content, low density, and excellent processability, making it suitable for demanding industrial environments. As a direct manufacturer, we enable downstream producers to achieve reliable compounding and consistent output across multiple sectors. The following sections outline real-world application scenarios, industry-specific compliance, formulation details, integration steps, and representative end products.

1. PV Encapsulant Film Manufacturing for Photovoltaic Modules

Downstream PV module manufacturers utilize our EVA primarily for the lamination layer in solar panels, where it provides long-term UV resistance and optical clarity. Operators combine Ateva 1609 with crosslinking agents and stabilizers to create sheets with tailored melt characteristics, essential for thermal encapsulation and module longevity. Strict quality control is maintained throughout film extrusion and lamination processes.

Industry compliance standards

• IEC 61215 (Crystalline silicon terrestrial PV modules design qualification and type approval)
• UL 1703 (Standard for Safety Flat-Plate Photovoltaic Modules and Panels)
• TÜV Rheinland 2 PfG 1169/08.2007 (PV module encapsulation materials requirements)
• RoHS Directive 2011/65/EU

Typical usage ratio

• 80%–92% EVA by weight in encapsulant blends, adjusted for targeted melt index and desired optical transmittance; remaining formulated with crosslinkers and additives

Downstream process integration

• Compounders melt-blend the resin with required additives, extrude into sheets (0.4–0.6 mm), and apply directly during module vacuum lamination under heat and pressure

Final product types

• PERC and monocrystalline silicon PV modules
• Thin-film photovoltaic laminates
• BIPV (Building Integrated PV) panels
• Flexible lightweight solar panels

2. Hot Melt Adhesive Formulation for Packaging and Bookbinding

Our EVA serves as the polymer backbone in industrial hot melt adhesives, where formulators rely on its tailored vinyl acetate content to ensure bonding strength, flexibility, and sprayability. Production involves premixing with waxes and tackifiers under precise temperature control. The resulting adhesives exhibit clean open time windows and strong adhesion to paper, cardboard, and select plastics.

Industry compliance standards

• FDA 21 CFR 175.105 (Adhesives for food packaging)
• EN 923:1997 (Adhesives - Terms and definitions for hotmelts)
• ISO 9001:2015 QMS for adhesive manufacturing
• REACH Regulation (EC) No 1907/2006

Typical usage ratio

• 30%–45% EVA by weight in total adhesive blend; actual loading tuned based on viscosity, open time, and substrate compatibility

Downstream process integration

• Melting and mixing in industrial jacketed kettles at 120–180°C, followed by homogenization with tackifiers/rosin and dispensing via slot-die or spray equipment onto substrates

Final product types

• Case and carton sealing adhesives
• Perfect binding adhesives for books
• Label adhesives
• Disposable hygiene adhesive products

3. Cable and Wire Insulation Compound Formulation

Industrial cable manufacturers integrate Ateva 1609 EVA to enhance flexibility, processing and environmental resistance of insulation layers for low- and medium-voltage wires. Crosslinking, flame retardancy, and pigment masterbatches are incorporated alongside EVA to ensure compliance with safety and performance regulations. On-line extrusion and irradiation crosslinking create uniform jackets with controlled physical and electrical properties.

Industry compliance standards

Typical usage ratio

• 55%–75% EVA by weight in the insulation blend; levels vary based on flame retardant and plasticizer content for specific cable class

Downstream process integration

• Blend loaded into twin-screw extruders, compounded with crosslinkers and flame retardants at 140–180°C, extruded over wire, and optionally irradiated for crosslinking

Final product types

• Low-voltage building wires
• Automotive wiring harness insulation
• Flexible appliance cords
• Solar photovoltaic cable jackets

4. Foam Sheet Production for Sports and Footwear

Downstream producers select this grade for closed-cell foam sheet manufacturing, utilizing its fine cellular structure for impact absorption, lightweight properties, and reliable resilience. Manufacturers combine EVA with blowing agents, crosslinkers, and colorants, then process via molding or continuous foaming lines. This setup meets high durability and safety demands in finished athletic and casual footwear.
