Applications of Braskem Evateno HM 150 EVA in Industrial Manufacturing

As the direct manufacturer of Braskem Evateno HM 150 EVA, we support key sectors that require high-performance ethylene-vinyl acetate copolymers for demanding processes. Our industrial partners in packaging, footwear, hot melt adhesives, cable compounds, and solar encapsulation benefit from material consistency, application-specific formulation flexibility, and regulatory compliance.

1. Food and Pharmaceutical Packaging Films

Flexible and semi-rigid films for food and pharmaceutical packaging rely on this resin for its sealing, flexibility, and low-temperature performance. Customers in film extrusion optimize oxygen and moisture barrier properties by fine-tuning resin ratios with LDPE and specialty additives. HM 150 EVA supports high-clarity demands, repeated heat sealing, and extended shelf life, while meeting strict compounding protocols.

Industry compliance standards

• FDA 21 CFR 177.1350 (ethylene-vinyl acetate copolymer resins)
• EU 10/2011 (plastic materials for food contact)
• USP <661.1> (plastic materials of construction for pharmaceuticals)
• GMP Compliance (EC 2023/2006)

Typical usage ratio

• 10–40% of total resin blend, adjusted based on sealing strength and barrier layer design; higher ratios in pharmaceutical blister films

Downstream process integration

• Dry blending with LDPE, LLDPE, and compatibilizer resins, followed by melt extrusion through blown or cast film lines
• Online metering and feed zone dosing ensure batch traceability and quality consistency

Final product types

• Vacuum and modified atmosphere food packaging films
• Pharmaceutical strip and blister packaging
• Heat-seal inner food pouches
• Dairy and meat cling wraps

2. Hot Melt Adhesive Formulations

EVA copolymers feature prominently in hot melt adhesive (HMA) systems, valued for controlled melt viscosity, bond flexibility, and fast-setting properties. Formulators blend HM 150 EVA with tackifiers, waxes, and stabilizers to create adhesives for product assembly, packaging, and bookbinding. Each application demands tailored ratios for open time, setting speed, and substrate compatibility.

Industry compliance standards

• FDA 21 CFR 175.105 (adhesives in indirect food contact)
• ISO 9001:2015 (quality management for adhesives)
• REACH (EC 1907/2006) chemical safety
• RoHS 2011/65/EU (for packaging adhesive on electronics)

Typical usage ratio

• 15–50% by weight of total adhesive formulation; high-VAc grades adjusted for open time and flexibility requirements

Downstream process integration

• Vacuum transfer into high-shear mixers and reaction kettles with continuous temperature monitoring
• Addition into adhesive compounding with solid ingredients to ensure homogeneous melting and dispersion

Final product types

• Hot melt adhesives for packaging and labelling
• Bookbinding spines and perfect binding agents
• Nonwoven hygiene product assembly adhesives
• Case and carton sealants for automated packaging lines

3. Cable Insulation and Jacketing Compounds

The electrical and communications cable sector uses EVA-based compounds for primary and secondary insulation, seeking a balance between flexibility, environmental stress crack resistance, and processability. EVA compatibilizes with flame retardants and plasticizers to deliver precise mechanical and dielectric properties. Our technical support aids compounders to configure robust insulation for medium- and low-voltage applications.

Industry compliance standards

• IEC 60502 (power cables with extruded insulation and sheath)
• UL 1581 (electrical wires, cables, and flexible cords)
• RoHS 2011/65/EU (lead, cadmium, and plasticizer limits)
• EN 50363-1 (insulating compounds for cables)

Typical usage ratio

• 5–30% in compound matrix; exact percentage tailored to flame retardant load, elongation, and softness targets

Downstream process integration

• Pre-mixing with inorganic fillers and fire retardants, then twin-screw extrusion for pelletizing
• Direct feeding into extrusion lines for continuous cable coating

Final product types

• Flexible power cable insulation
• Signal and data transmission sheathings
• Mining and marine cable jacketing
• Low-smoke zero halogen (LSZH) cable components

4. Footwear Injection and Compression Molding

Our raw material supports footwear sole and midsole production due to its resilience, cushioning, and corrosion resistance. Shoe manufacturers process EVA blends through injection and compression molding to deliver stable mechanical cushioning, precise foaming, and surface finish. The ratio and cell structuring are crucial for sports, leisure, and safety shoe markets.

Industry compliance standards

• EN ISO 20345:2022 (personal protective footwear)
• REACH (EC 1907/2006) authorization for footwear
• GB 28011-2011 (safety footwear for the Chinese market)
• Phthalate and heavy metal content checks (consumer goods directives)

Typical usage ratio

• 30–100% as the main polymer base, adjusted for desired density, flexibility, and expansion ratio in cross-linked foams

Downstream process integration

• Blend with blowing agents, cross-linking agents, and color masterbatches, then loaded into injection or compression moulds
• Thermal curing controls cell size and rebound properties

Final product types

• Sports shoe midsoles and outsoles
• Flip-flop and sandal base plates
• Work boot shock-absorption soles
• Children’s and leisure footwear components

5. Photovoltaic Module Encapsulation Sheets

Solar panel manufacturing depends on EVA encapsulant sheets for critical optical, adhesion, and weathering properties. Encapsulant film processors select HM 150 grade for reliable cell bonding, UV stability, and thermal cycling resistance. Process control in extrusion and sheet calendaring ensures consistent gel content and minimal shrinkage, directly influencing module lifetime.
