Sealing tape for closing polycarbonate - 75 mm

Product detailed description

Self-adhesive tape made of a solid corrugated material with a plastic surface and acrylic adhesive applied on one side. It is used to close the cavities of polycarbonate sheets. Thanks to the strong adhesive, the tape is sufficiently resistant to damage, even in outdoor environments. Additionally, the tape sufficiently adapts to most PC sheets during thermal stress or their linear thermal expansion. This is the solid (non-perforated) variant of the tape.

Functional properties

• The tape contracts and expands together with the polycarbonate sheet.
• Effective at high and low temperatures (-30°C ~ +80°C); minimum application temperature: +10°C.
• Excellent moisture resistance.
• Durable, strong outdoor adhesive.
• Perfect adhesion on irregular surfaces.
• Developed for polycarbonate applications.

Selection and installation

When purchasing the tape, you need to think about what tape width you will need. Of course, it is better to have a tape half a centimeter too wide than 1 mm too narrow. Below are general recommendations for choosing the tape according to the thickness of the polycarbonate sheet.

• Polycarbonate 4 mm - tape width 28 mm
• Polycarbonate 6 mm - tape width 28-38 mm
• Polycarbonate 8-10 mm - tape width 38-60 mm

During application, the surface of the sheet must be dry and free of grease. The tape, which has adhesive applied to one side, is then applied. Another advantage of the ventilation tape is that it is very easy to recognize the spots where it needs to be renewed over time.

Even proper use of mounting tapes cannot prevent condensation from forming in the sheet's cavities. Polycarbonate allows water vapor to pass through the sheet walls into the cavities and vice versa. This is a natural physical phenomenon caused by the difference in air humidity concentration and temperature between the interior and exterior sides. Once conditions stabilize, the condensation disappears again.
