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

FAQs

Frequently Asked Questions

What is Lotte Chemical EVA LVS520 and what makes it different from other foam EVAs?
LVS520 is a 22% VA EVA copolymer engineered for foam and injection molding. Compared to standard 18–19% foam EVAs, it offers greater softness, flexibility, and energy-efficient processing-making it ideal for comfort footwear and soft foam products.
Foam shoe soles, insoles, footbeds, sandals, slippers, injection/sheet molded parts, cushion pads, sports/industrial padding, and custom foam blocks.
LVS520 (22% VA, MFI 3.0) is softer and more comfort-oriented than LVS430 (18% VA, MFI 2.0), which is stiffer and designed for athletic/performance footwear. Choose LVS520 for comfort and soft foam; LVS430 for athletic support.
Kneader: 70–100 °C; Roll mill: <110 °C; Melt temp: 79 °C; Foam molding: 150–170 °C, 100–150 kg/cm², 30–60 min. LVS520’s low melt point allows moderate processing temperatures, protecting additives and material.
LVS520 is generally FDA and EU compliant for EVA copolymers, but specific food/skin contact suitability depends on the full formulation and migration testing. Consult Lotte Chemical or your distributor for compliance certificates.
Higher VA improves additive compatibility, softness, flexibility, and uniform cell structure-delivering superior comfort, elasticity, and energy return in foam products.
Generic “EVA 22% VA foam” listings risk brand confusion and inconsistent quality. Jitsy ensures you get authentic Lotte LVS520 with full technical data-delivering batch-to-batch reliability, regulatory compliance, and premium foam performance.
