Adhesive Foam Tape 3M PRESTOPOR 1 m x 8 cm – single nonwoven strip

3M PRESTOPOR adhesive foam tape, 1 m x 8 cm, is a single nonwoven strip designed for sealing, padding and vibration damping in construction and installation applications. The tape combines a compressible foam core with a pressure-sensitive adhesive backing to form a flexible seal or spacer that conforms to irregular surfaces and gaps. It is suitable for use around windows and doors, between panels, and in other joints where a resilient, adhesive foam layer is required.

Advantages

The product offers a compressible foam structure that adapts to uneven surfaces and maintains contact under pressure. Its pressure-sensitive adhesive backing provides immediate tack and reliable adhesion to a range of substrates, enabling quick installation without additional fasteners. The nonwoven facing on the foam strip improves handling and allows for neat application along edges and joints. The tape contributes to noise and vibration reduction while creating a flexible seal that resists displacement under normal service conditions.

Suitable for

• Sealing gaps around window and door frames
• Packing and spacing between panels and trim
• Cushioning and vibration isolation in installations
• Edge protection and surface contact where compression is needed

Key specifications

• Length: 1 metre
• Width: 8 centimetres
• Construction: compressible foam core with pressure-sensitive adhesive backing and nonwoven facing
• Function: sealing, padding, cushioning and vibration damping
• Form: single continuous nonwoven strip

How to use

Ensure surfaces are clean, dry and free of dust, oil or loose particles before application. Measure and cut the required length from the strip, remove the protective liner from the adhesive side, and press the tape firmly into place along the joint or edge, applying even pressure to ensure full contact. For best results, apply at moderate temperatures and avoid stretching the tape during installation. Trim any excess material with a sharp knife or scissors for a neat finish.

Usage recommendations

Use the tape on compatible substrates such as painted or unpainted wood, metal and many plastics; test adhesion on sensitive surfaces first. For long-term outdoor exposure, consider additional mechanical fastening or protective cover as appropriate for the application. Store the roll flat in a cool, dry place away from direct sunlight and high humidity to preserve adhesive performance.
