Ventilation Tape for Sealing Polycarbonate - 28 mm

Product detailed description

A self-adhesive tape made of durable polypropylene non-woven fabric with a one-sided acrylic adhesive coating. It is used to seal the cells of polycarbonate sheets. Thanks to its strong adhesive, the tape is sufficiently resistant to damage, even in outdoor environments. The tape also adapts well enough to most PC sheets during thermal stress or their linear thermal expansion.

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 resistance to moisture.
• Durable, strong outdoor adhesive.
• Perfect adhesion to irregular surfaces.
• Developed specifically for polycarbonate applications.

Selection and installation

When purchasing the tape, you need to consider what tape width you will need. Of course, it's better to have a tape half a centimeter wider than one millimeter 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 on one side, is then applied. Another advantage of the ventilation tape is that it makes it very easy to recognize where restoration will be needed over time.

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

Technical parameters

• Roll length: 33 m
• Tape width: 28 mm
• Tensile strength: 70 (N/15mm)
• Elongation at overload: >50 (%)
• Water permeability: 10 l/m²
• Air permeability: 750 l/m²

The tape is treated in a way that guarantees medium-term resistance to aging. The tape is coated with a high-quality synthetic pressure-sensitive adhesive specifically designed for this type of application. The adhesive is applied over the entire surface in a pattern that imitates the tape's perforations.
