EVA Film Quality Specification

There is attached file which clarify the factory inspection standards.

1)Crystal point definition

Excessively polymerized solution residues such as heterochromatic dots, stripes, and spots inside the interlayer

2)Water ripple

Rippled marks on the surface of the interlayer

3)Spot defect

The bubbles and other visible inclusions remaining in the interlayer during the production process, the paste points caused by the excessive decomposition of peroxy compounds, the oil stains and teardrops adhering to the surface of the interlayer, etc.

4)Cross link
Cross-linking refers to the process in which linear or branched polymers are connected by chemical bonds to form a network or three-dimensional polymer. The degree of cross-linking is a measure of the degree of cross-linking, expressed as a percentage.
