Lotte Chemical EVA VA800 is a premium, autoclave-process ethylene-vinyl acetate (EVA) copolymer engineered for fast-extrusion hot melt adhesive (HMA) formulations, automotive, and specialty bonding. With 28% vinyl acetate, ultra-high MFI 20 g/10 min, density 0.950 g/cm³, melting temperature 69°C, Vicat <40°C, Shore D 25, and a dual-additive package (antioxidant + free flow agent), VA800 delivers exceptional adhesion, ultra-fast processability, and reliable low-temperature sealability for high-speed adhesive production. Manufactured via ExxonMobil Chemical’s autoclave process with strict contaminant control and uniform VA/MI, VA800 is trusted by India’s top HMA, packaging, and automotive adhesive manufacturers.
Functional Features & Technical Authority
- 28%-VA-Adhesive: High polarity ensures strong adhesion to paper, cardboard, plastic, leather, fabric, and metal—no tie-layer needed.
- 20-MFI-Ultra: Ultra-high melt index enables extrusion 3–4x faster than standard HMA EVA, ideal for rapid stick and cartridge production.
- Flow-Agent: Built-in free flow agent guarantees smooth, uninterrupted extrusion at maximum speed, reducing downtime and pressure.
- Antioxidant-Protected: Antioxidant additive provides thermal stability, preventing oxidative degradation and extending shelf life.
- Autoclave-Premium: ExxonMobil autoclave process ensures consistent, premium quality and batch-to-batch reliability.
- Uniform VA/MI: Delivers consistent adhesive performance and quality across high-speed production.
- Strict Contaminant Control: Low gel level for defect-free, clean adhesive compounds even at rapid throughput.
- Regulatory Compliance: Conforms to FDA 21 CFR 177.1350, ASTM D1238/D1505/D2240/D1525, ISO 9001/14001/TS16949, and automotive standards.
Applications
Lotte EVA VA800 is optimized for fast-extrusion hot melt adhesive sticks, rapid cartridge adhesives, high-speed packaging adhesives (carton sealing, edge banding, lamination), rapid assembly adhesives, and automotive mat coating.
