Above is the water absorption comparison after breaking .
Water absorption rate |
EVA |
PVB |
0.5% |
4% |
For some special application environment ( for example : shower room, swimming pool ) , water absorption is likely to cause de-lamination or haze at the edge of laminated glass . With oster EVA film , it wouldn’t be a problem for all the laminated glass manufacturers.
Transmittance |
> 92% |
Haze |
< 0.3% |
Cross-linking rate |
> 90% |
Adhesion with glass |
>100N/CM |
Tensile strength |
>22MPA |
UV filtering rate |
>99% |
