A. Tapes for 2-ply laminates:
1. Tapes for 2-ply laminates with a microporous hydrophobic moisture-permeablewaterproof membrane
Tape substrate: non-thermoplastic crosslinked PU film
an extremely thin and elastic version of MELCO™ FU-700 tape, using thinner and lower modulus film.
When tape is welded onto a thin, flexible waterproof material, the outline of the tape sometimes becomes visible from the outside of the material.
MELCO™ FU-750 tape was created to minimize such problems.
Using non-thermoplastic film as a tape substrate gives MELCO™ FU-700 and FU-750 tapes unmatched quality.
These tapes can be conveniently applied using an iron, without having to worry about specific heat adjustments.
San Chemicals, Ltd. is the only company currently offering this type of tape.
* White color is also available for FU-700
Tape substrate: thermoplastic PU film
uses thermoplastic film which will melt if excess heat (in excess of film’s melting point) is applied.
Close attention must be paid to the welding conditions and welding speed.
Although other companies offer thermoplastic-type film tapes, MELCO™ FU-777 tape provides vastly superior performance.
Heat adjustments are easier to make with FU-777 tape due to its design
(the difference in heat properties between the tape substrate and the hotmelt adhesive is set as wide as possible for better and easier application).
2. Tape for 2-ply laminates with a non-porous hydrophilic moisture-permeable waterproof membrane
an extremely thin and elastic tape, using non-thermoplastic PU film as substrate.
Sometimes when tape is welded onto a thin flexible waterproof material, the outline of the tape becomes visible from the outside of the material.
MELCO™ XF-8505 tape minimizes this problem.
