A manufacturer of a caulk free peel-and-stick trim for bathtubs, showers and countertops was looking for an improved extrusion process to both upgrade their product and eliminate third-party costs. Previously, the caulking tape was composed of two separate pieces — butyl and adhesive tape. Diamond America engineered a heated, precision application process that allowed for the butyl to be formed inline with the tape in a single V-shape. The company is currently testing the process with the Diamond America TT100 extruder and forming die in a production atmosphere.

The Diamond America process will eliminate third-party expenses (compound tape form), increase the tape’s adhesion, and improve performance of the product by eliminating seams.
