Lotte EVA LVS430

Lotte LVS430 is a premium 18% ethylene vinyl acetate (EVA) copolymer resin engineered by Lotte Chemical Corporation (South Korea), designed for high-performance foam, footwear, injection, and sheet molding applications. Produced via advanced high-pressure tubular polymerization, LVS430 offers unmatched foaming, mechanical strength, and processing consistency. 

LVS430 is manufactured with tight control over molecular weight and vinyl acetate distribution, resulting in predictable processing and minimal batch variance (<2%). Physical form: white/natural pellets, 25 kg bags. Contains thermal stabilizers (300 ppm typical), no slip/anti-block, allowing custom additive integration. Fully compliant with ISO 9001:2015, RoHS, REACH, and ASTM standards. 

Processing Guidelines

  • Foam Molding: 1–3% blowing agent (azodicarbonamide or CO₂); mold at 160–180°C; density 40–150 kg/m³ 
  • Injection/Sheet Molding: Barrel 150–180°C; MFI 2.0 ensures smooth cavity fill, minimal defects 
  • Extrusion: Tubes, strips, profiles; process at 150–180°C; avoid >190°C 
  • Best Practices: Keep material dry, avoid excessive residence time, regular purging 

Performance Advantages 

  • Foaming: Uniform expansion, fine cell structure, minimal voids—critical for comfort and durability 
  • Mechanical: High tensile strength (260 kgf/cm²), elongation (~750%), 92 Shore A hardness 
  • Temperature: Low melting point (86°C) reduces energy use, shortens cycle times 
  • Chemical/Environmental: Resistant to oxidation, UV, ozone, common chemicals; flexible to -40°C

FAQs

Frequently Asked Questions

What is the core composition and manufacturing process of Lotte LVS430?
Lotte LVS430 is an 18% vinyl acetate EVA copolymer created via high-pressure tubular polymerization. This advanced process results in tightly controlled molecular weight and VA distribution-ensuring batch-to-batch uniformity, high elasticity, and optimal foaming behavior. The resin is supplied as white/natural pellets and is free from slip/anti-block additives, allowing for custom additive integration.
LVS430 is specifically engineered for superior foaming, enabling lightweight, resilient, and comfortable foam with consistent cell structure. Its unique formulation ensures minimal voids, excellent compression set, and long-term durability, making it a top choice for high-volume footwear and foam sheet manufacturers.
With a melt flow index of 2.0, LVS430 offers smooth flow, excellent cavity filling, and minimal processing defects. It supports complex geometries and delivers high mechanical strength and flexibility, making it ideal for flexible connectors, grips, and molded cushioning components.
LVS430 features a density of 0.940 g/cm³, a melting point of 86°C, and a tensile strength of 260 kgf/cm². It maintains flexibility at low temperatures (down to -40°C) and offers high elongation (~750%), making it suitable for demanding cushioning and insulation applications.
The resin’s low melting point reduces energy consumption and shortens cycle times. Its batch consistency (<2% variance) minimizes production scrap, while thermal stabilizers prevent degradation during processing. LVS430 is also highly compatible with fillers, pigments, and blowing agents.
LVS430 is fully compliant with ISO 9001:2015, RoHS, REACH, and ASTM standards. Each batch is supplied with a Certificate of Analysis (CoA), origin verification, and, if required, third-party lab testing-ensuring traceability and regulatory peace of mind for B2B buyers.
JITSY provides polymer engineer support for all processing, troubleshooting, and custom formulation needs. Flexible order quantities, rapid pan-India delivery, and transparent supply ensure buyers get the right material, when and where needed, with full documentation and quality assurance.
