Lotte EVA LVS520
Lotte Chemical EVA LVS520 is a next-generation, high-VA ethylene-vinyl acetate (EVA) copolymer engineered for foam applications, injection molding, and comfort-centric footwear. Developed by Lotte Chemical (South Korea) using proprietary tubular process technology, LVS520 stands out for its superior softness, fine-cell foamability, and robust mechanical properties-making it the top choice for Indian footwear manufacturers, foam converters, and cushion product makers.
With a melt flow rate (MFI) of 3.0 g/10 min, vinyl acetate content of 22 wt%, density 0.943 g/cm³, tensile strength at break 200 kg/cm² (~19.6 MPa), elongation at break 750%, Shore hardness 78A, Vicat softening 53 °C, and melt temperature 79 °C, LVS520 delivers unmatched foam softness, flexibility, and energy-efficient processing. Its high VA content and moderate MFI enable precise compounding, uniform cell structure, and soft, durable foam products-ideal for comfort footwear, sports pads, and custom molded foam parts.
Functional Features & Technical Authority
- High VA Content (22% VA): Delivers exceptional softness, elasticity, and comfort-outperforming standard 18–19% foam EVAs for premium feel and flexibility.
- Optimized MFI (3.0): Supports controlled foam mixing, uniform additive dispersal, and easy flow in injection and sheet molding equipment, reducing defects and boosting productivity.
- Fine-Cell Foamability: Proprietary process ensures fine, uniform cell structure for lightweight, soft, and resilient foam products.
- Low-Temperature Processing: Melt temperature of 79 °C and Vicat 53 °C allow for energy-efficient, thermally gentle processing-preserving material integrity and additive performance.
- Soft Yet Durable: Shore A 78 and 750% elongation provide a cushioned feel with robust mechanical support, resisting cracking and fatigue over repeated use.
- Excellent Mechanical Strength: Maintains tensile strength (200 kg/cm²) and flexibility even after crosslinking and foaming, ensuring long-term durability in footwear and cushioning.
- Versatile Processing: Readily processable in kneading, milling, injection, and sheet molding setups-compatible with standard equipment and a wide range of foam formulations.
- Consistent Quality: Lotte Chemical’s global pedigree ensures batch-to-batch reliability, traceability, and regulatory compliance.
Applications
Foam Shoe Soles & Footwear Components:
LVS520 is the benchmark for soft, comfortable EVA foam shoe soles, insoles, and footbeds-delivering superior cushioning, flexibility, and impact absorption for casual, comfort, and recreational footwear. Its high VA content ensures a plush, premium feel while maintaining structural support.
Injection Molding & Sheet Molding:
Ideal for injection-molded EVA parts (grips, handles, decorative elements) and sheet-molded foam products (custom foam sheets, thermoformed pads, blocks). LVS520’s MFI 3.0 allows for smooth flow and easy coloring, supporting complex shapes and detailed parts.
Cushion Products & Protective Padding:
Perfect for sports equipment padding, industrial cushioning, protective packaging, mats, and playground surfaces. Fine-cell foam structure and high elongation enable effective impact absorption and comfort.
General EVA Foam & Industrial Compounds:
Adaptable for custom foam formulations, general foam sheets, blocks, and as a modifier resin to boost softness and flexibility in blends for technical and consumer applications.
Key Application Highlights:
- EVA foam shoe soles, insoles, footbeds, sandals, slippers
- Injection-molded EVA parts and foam sheets
- Cushion pads, sports/protective padding, comfort layers
- Custom foam blocks, industrial compounds, modifier resin
