Alongside our portfolio of products for float glass, we offer a range of interleaving powder for specialty glass applications, including laminated and mirrored glass.
Our cross-linked polystyrene interleavant replaces the use of steel, wood or cork spacing bars in architectural lamination autoclaves. Our product has been tested extensively in autoclaves by Dupont as part of its laminated glass production process using the Butacite® range of PVB interlayers.
Mirrored glass products require particular care in the selection of an interleavant, which must be acid free. In addition, the paint used on the back of the mirror must be adequately dried or cured before the interleavant polymer is applied, otherwise it will be lost in the coating and hence offer no protection. Our powder offers the best protection in this application, however, a relatively high dosage compared to a float line is required to ensure that the powder is more evenly distributed.
