Double sided foam tape thickness is not one universal number. It may mean foam core thickness, finished tape without liner, or total caliper with liner. Density, adhesive build, gauge pressure, compression, surface, load, temperature, and dwell affect how a nominal thickness behaves. Treat values as reference data and confirm the actual assembly by sample testing before full use.
EPDM sponge specific gravity should be read with apparent density, cell structure, compression behavior, and specimen condition, not as one universal number. This reference applies to cellular EPDM used as sheet, gasket, cushioning substrate, or adhesive-tape backing. Published ranges support comparison only; confirm the tested grade under the intended surface, load, temperature, and process conditions.
Adhesive tapes for foam converting must do more than create an initial bond. They must laminate cleanly to the foam, stay dimensionally stable through slitting or die cutting, release from the liner at the right moment, and continue performing after the converted part is assembled. This solution is intended for foam gaskets, sealing strips, pads, spacers, vibration-control parts and similar components made from PE, EVA, PU, EPDM, neoprene and other foam substrates. The main risks are poor wet-out, edge lifting, adhesive transfer, foam compression, liner instability and cutting distortion. Selection should therefore balance the foam surface, adhesive construction, carrier, liner, converting method, load and service environment.
