EVA Resin Grades

Ethylene Vinyl Acetate (EVA) is a flexible thermoplastic copolymer built from ethylene and vinyl acetate. It is defined by two parameters — VA content (5–40%) and Melt Flow Index (MFI) — and appears as translucent to transparent pellets. The balance of these values tunes softness, clarity, adhesion and processability.

FAQ

Frequently Asked Questions

What is EVA resin?

EVA (Ethylene Vinyl Acetate) is a thermoplastic copolymer of ethylene and vinyl acetate. It combines rubber-like flexibility with easy thermoplastic processing and is supplied as translucent to transparent pellets.

How to choose VA content?

VA content sets the property balance: 5–9% gives PE-like toughness, 9–18% suits films, 18–28% is used for hot-melt adhesives, and 28–40% is preferred for foam and PV encapsulant film.

What does MFI mean?

Melt Flow Index (measured at 190°C / 2.16 kg) indicates melt flowability. Lower MFI means higher viscosity and strength; higher MFI means easier filling and faster cycling.

Can I get technical data?

TDS available on request for your selected grade. Share your target VA content and application so we can provide the matching data sheet.

MOQ & lead time?

Minimum order quantity and lead time depend on grade and volume. Contact us with your grade and required volume for a quotation.
