SK Functional EVA Evatane 28-40
SK Functional EVA EVATANE 28-40 (formerly Arkema) is a premium, balanced-flow ethylene-vinyl acetate (EVA) copolymer engineered for hot melt adhesive (HMA) formulations and multi-purpose applications, including packaging, film extrusion, automotive assembly, and consumer goods. Manufactured via high-pressure radical polymerization, this grade delivers excellent processing characteristics, superior tackifier compatibility, and reliable adhesion across diverse substrates. With 28% vinyl acetate, MFI 40 (35-45), antioxidant stabilization, and strict contaminant control, EVATANE 28-40 ensures batch-to-batch consistency, versatile extrusion speeds, and robust multi-purpose performance-making it the preferred choice for Indian manufacturers seeking balanced HMA and multi-purpose solutions.
Functional & Technical Features
- Balanced-Flow Processing: Optimized for standard to moderately fast HMA extrusion, enabling flexible production speeds and reliable application control.
- Tackifier Compatibility: Strong interaction with all standard tackifying resins and waxes, supporting robust adhesive formulations and flexible selection for formulators.
- Superior Adhesion: Delivers excellent bonding to paper, board, plastics, and other substrates, making it ideal for packaging, assembly, and consumer goods.
- Antioxidant Stabilization: Built-in antioxidant package protects against thermal degradation during HMA processing and storage, ensuring product longevity and reliability.
- Versatile Application Capability: Suitable for HMA, film extrusion, lamination, automotive assembly, and specialty coatings—providing flexibility for multi-purpose and custom applications.
- Consistent Quality: Uniform VA content and MI, strict contaminant control, and batch validation guarantee predictable performance for every use-case.
- Thermal & Mechanical Reliability: Good low-temperature sealability (Vicat 43°C), excellent elongation (800%), and mechanical strength for durable, flexible adhesive bonds and films.
Applications
SK EVATANE 28-40 is the material of choice for:
- Hot Melt Adhesive Formulations: Used in glue sticks, cartridge adhesives, packaging adhesives (carton sealing, edge banding), lamination, assembly, and consumer goods bonding—delivering balanced flow and robust adhesion.
- Packaging & Film Extrusion: Ideal for cast/blown film, flexible packaging, lamination, and multi-layer structures, offering excellent film-forming properties and adhesion to a variety of substrates.
- Automotive & Specialty Applications: Supports automotive assembly adhesives (interior trim, component bonding), specialty coatings, and custom formulations requiring versatile processing and reliable performance.
Key Application Benefits:
- Flexible production speeds and robust process control.
- Consistent bonding and film quality across batches.
- Reliable performance in packaging, automotive, and specialty segments.
