PVA and PET are layered! Applications as a "water-soluble" process sheet are expected.
The "SO Sheet" is a film made by layering PVA (polyvinyl alcohol) and PET (polyethylene terephthalate). It can be utilized as a transfer substrate for functional patterns (resist, metal, functional resins, etc.) created through various printing and coating processes on the PVA layer. By combining with PET, the dimensional stability is enhanced compared to a standalone PVA film, making it possible to maintain the shape of fine structures that were previously difficult to achieve. Applications as a "water-soluble" process sheet are expected in areas such as three-dimensional lithography, removal of sacrificial layers and self-supporting films, and temporary protection within processes. 【Features】 ■ Can be used as a support for functional patterns and printed patterns, as well as a carrier film. ■ Capable of maintaining the shape of fine structures. *For more details, please refer to the PDF document or feel free to contact us.
