Applications of Braskem Evateno 8019PE EVA in Industrial Manufacturing

As a direct manufacturer, we supply Braskem Evateno 8019PE EVA to a range of downstream sectors where performance criteria, compliance, and processability are crucial for consistent, industrial-scale production. The following sections detail established real-world applications, including reference standards, technical usage guidelines, key stages in production, and output classifications for each industrial segment.

1. Photovoltaic Encapsulant Film Production

Solar module manufacturers select our EVA in formulating encapsulant sheets that demand excellent crosslinking, high optical clarity, and long-term durability under UV exposure. Our resin ensures stable lamination, sheet extrusion, and crosslinking, meeting the module qualification test regimes required by energy markets worldwide.

Industry compliance standards

• IEC 61215: Crystalline silicon terrestrial PV modules – Design qualification and type approval
• IEC 61730: Photovoltaic module safety qualification
• UL 1703: Standard for Flat-Plate Photovoltaic Modules and Panels
• RoHS Directive (EU) 2015/863 compliance for restricted substances

Typical usage ratio

• 60–80 wt% in the final film, adjusting with co-polymers or additives based on curing and transparency needs.

Downstream process integration

• Added to the extruder during melt compounding, followed by calendaring to form films. The films undergo crosslinking via lamination processes with peroxides. Our material provides controlled gel content for curing and lamination cycle stability.

Final product types

• Photovoltaic encapsulant sheets
• Pre-laminated solar cell modules
• Backsheet-laminated composite films for PV panels

2. Hot Melt Adhesive Formulation

Hot melt adhesive compounders incorporate this EVA grade for its combination of flexibility, tack, and compatibility with tackifiers and waxes. These features remain consistent in high-speed packaging, woodworking, and bookbinding operations, where thermal performance and mechanical bond strength must align to sector-specific standards.

Industry compliance standards

• FDA 21 CFR 175.105 for indirect food contact adhesives (for non-food-facing surfaces)
• REACH Annex XVII for restricted chemical content
• ASTM D1876: Peel Resistance of Adhesives
• ISO 11339: T-Peel Test for flexible-to-flexible bonded assemblies

Typical usage ratio

• 20–55 wt% as the base polymer in adhesive blends, with ratio adjustments based on viscosity, open time, and required adhesion strength for the target application.

Downstream process integration

• Introduced into high-shear mixers and extrusion reactors for compounding with resins and plasticizers, pelletizing the blended hot melt, and subsequent remelting during adhesive application in downstream assembly or packaging lines.

Final product types

• Bookbinding adhesives
• Carton and case sealing adhesives
• Pressure-sensitive labeling adhesives for industrial and retail packaging

3. Cable Sheath and Insulation Compounds

The wire and cable sector employs our EVA resin as a matrix polymer in low-voltage insulation and jacketing, where electrical properties, flexibility at low temperatures, and resistance to oil and chemicals are strictly defined. The selection and polymer modification respond directly to flame retardancy and physical testing standards established by electrical authorities.

Industry compliance standards

• IEC 60502-1: Power cables with extruded insulation and their accessories
• UL 758: Appliance Wiring Material
• RoHS Directive (2011/65/EU) for hazardous substance restriction
• EN 50363-4-1: Insulating compounds based on EVA for cables

Typical usage ratio

• 25–40 wt% in cable compound, typically blended with flame retardant fillers; formulation varies to balance insulation resistance and processing flow.

Downstream process integration

• Combined with specific grades of fillers and crosslinking agents during premix, then compounded via twin-screw extruders. Melt-blended composite is pelletized and then extruded as a sheath or insulation layer over conductors on cable production lines.

Final product types

• Flexible power cable jackets
• Low-voltage insulation for appliance wiring
• Cable compounds for automotive harness applications

4. Footwear Injection and Compression Molding

In sports and safety footwear manufacturing, our EVA serves as a key component in midsole and outsole foams, valued for shock absorption, resilience after repeated flexing, and precise cell structure in expanded foam applications. Producers tune the resin ratio and process settings for compliance with footwear safety and durability assessment protocols.

Industry compliance standards

• ISO 20344: Personal protective equipment – Test methods for footwear
• EN ISO 20345/20347: Safety and occupational footwear requirements
• REACH Regulation (EC) No 1907/2006 for chemical substances
• SATRA TM77: Slip resistance of footwear outsoles

Typical usage ratio

• 35–65 wt% in EVA foam block, with the range determined by desired expansion ratio, hardness, and rebound properties for midsoles versus outsoles.

Downstream process integration

• Fed into high-pressure or low-pressure injection machines, or batch compression molding lines, combined with blowing agents and crosslinkers. Process controls compression, steam expansion, and final cell structure cure to achieve required comfort and physical metrics.

Final product types

• Sport and casual shoe midsoles
• Safety boot outsoles
• Shock-absorption insole boards

5. Flexible Packaging Film Co-Extrusion

Producers of multilayer film structures integrate EVA to improve sealing, clarity, and puncture resistance, especially for flexible packaging targeting food, hygiene, and medical products. The inclusion of EVA allows optimization of heat seal performance and film mechanicals following sectoral regulatory screenings.

Industry compliance standards

• FDA 21 CFR 177.1350 for food contact polyolefin plastics
• EU Regulation (EU) No 10/2011 on plastic materials for food contact
• ISO 527: Determination of tensile properties of plastics films
• GMP EC 2023/2006: Good Manufacturing Practice in food packaging plastics

Typical usage ratio

• 5–25 wt% in the target layer, increased for high-clarity films and minimised where sealability is the primary modification need.

Downstream process integration

• Metered into film extrusion equipment via gravimetric blenders, co-extruded with LDPE or other polyolefins to create multilayer films; EVA-rich layers form inner or sealant layers, receiving corona or flame treatment for downstream printing if required.

Final product types

• Lamination films for flexible packaging
• Stretch and shrink wrap films
• Sealant layers for food packaging bags and sheets
