EVA PRODUCT RANGE

Ethylene–vinyl acetate
grade portfolio

Ten commercial grade references covering VA contents from 18 to 33 wt.% and multiple melt-index ranges.

01 / MATERIAL BASICS

Two screening variables: VA content and melt index.

EVA is a copolymer of ethylene and vinyl acetate. Grade behavior changes with composition, molecular structure and flow characteristics.

VA content and melt index are useful starting points, but they do not replace application testing. Additives, processing conditions and the finished-product specification all affect the final result.

VA CONTENT

18–33 wt.% references

Higher VA content generally changes polarity, flexibility and compatibility. Use the TDS for grade-specific values.

MELT INDEX

3–45 g/10 min references

The listed range supports different conversion and formulation routes. Test conditions must match the current TDS.

QUALIFICATION

Process and end-use trials

Screen the data, request samples, then validate the grade under actual equipment and product conditions.
