LG Chem EVA EA28025
LG Chem EVA EA28025 is a premium, dual-purpose ethylene-vinyl acetate (EVA) copolymer designed for hot melt adhesive (HMA) formulations and foam applications. With 28% vinyl acetate, MFI 25 g/10 min, density 0.950–0.951 g/cm³, elongation 850%, and Shore A 76, EA28025 delivers exceptional adhesive compatibility, outstanding flexibility, and reliable low-temperature sealability.
Manufactured by LG Chem (South Korea) with strict contaminant control and uniform VA/MI distribution, EA28025 is the trusted resin for packaging adhesives, foam cushioning, footwear assembly, lamination, and cable insulation. Its balanced flow, high polarity, and excellent additive compatibility ensure consistent batch-to-batch performance and versatile processing for India’s leading adhesive, foam, cable, and specialty manufacturers.
Functional Features & Technical Authority
- Uniform VA & MI: Consistent vinyl acetate content and melt index across batches guarantee stable adhesion, flexibility, and processing—eliminating production variability.
- HMA-Optimized Compatibility: Seamlessly blends with tackifying resins, waxes, plasticizers, and antioxidants, enabling simple, stable hot melt adhesive formulations for packaging, bookbinding, woodworking, and product assembly.
- Dual-Purpose Versatility: Designed as a single resin for both HMA and foam—reducing inventory, simplifying procurement, and supporting a wide range of bonding and cushioning applications.
- Outstanding Flexibility: 850% elongation ensures soft, resilient foam and flexible adhesive bonds that withstand thermal cycling, mechanical loading, and repeated use.
- Strict Contaminant Control: Low gel level and clean resin ensure defect-free films, adhesives, and foam products—critical for packaging, lamination, and consumer applications.
- Excellent Low-Temperature Sealability: Vicat 45°C and high VA provide reliable adhesion and foam flexibility, even in cold storage or winter conditions.
- Good Organoleptic Property: Transparent, odour-neutral resin suitable for food-contact and consumer applications.
- Regulatory Compliance: Meets FDA 21 CFR 177.1350 and ASTM D6400; documentation available via authorized LG Chem distributors.
Applications
Hot Melt Adhesive (HMA) Base Resin (Primary):
EA28025 is the benchmark for packaging adhesives, lamination, bookbinding, woodworking, and product assembly. Its high VA delivers strong adhesion to paper, cardboard, plastic, metal, fabric, and leather. Balanced MFI and excellent compatibility enable efficient blending with resins, waxes, and additives, producing stable, flexible, and durable bonds for a wide range of end uses.
Foam Applications (Secondary but Significant):
Ideal for foam shoe soles, insoles, cushioning pads, and comfort layers, EA28025’s high elongation (850%) and 28% VA provide soft, responsive, and reliable foam for footwear, sports equipment, and industrial cushioning. Its consistent properties ensure reliable foam density, cell structure, and flexibility.
Wire & Cable Compounds:
Used for cable insulation and jacketing, EA28025 delivers flexibility, low-temperature performance, and good adhesion to metal and polymer cable components—supporting semi-conductive and specialty cable applications.
Specialty & Industrial Uses:
Perfect for extrusion coating on paper, foil, or film, thermal laminates, and custom compound formulations-where strong, flexible, and clean EVA is required.
Key Application Highlights:
- Packaging, lamination, woodworking, bookbinding adhesives
- Foam shoe soles, insoles, cushioning, comfort padding
- Cable insulation, jacketing, semi-conductive compounds
- Thermal lamination, extrusion coating, specialty bonding
