Tesa 4957 4957 White Foam Tape, 12mm x 25 m, 1.1 mm Thick

This foam tape is a closed-cell polyethylene product designed for adhesive joining and sealing tasks where moderate temperature exposure and biocompatibility considerations apply. It combines a pressure-sensitive tackified acrylic adhesive with a double-ended configuration to provide continuous contact along applied surfaces and is supplied on a 25 m roll for extended use.

• 80°C maximum operating temperature provides heat-resistant performance
• Tackified acrylic adhesive gives high initial tack and adhesion
• 4 adhesion rating ensures a firm bond to common substrates
• 6 N/cm tensile strength resists shear and peel forces
• Double-ended format enables adhesive on both sides for mounting

• Suitable for sealing joints in temperature-challenged assemblies
• Ideal for attaching components in medical device manufacturing
• Used with panels and trims for vibration-damping joints
• Can be used for gasketing small enclosures and housings
• Suitable for secondary bonding in prototyping and production

The backing is closed-cell polyethylene foam, which offers controlled compressibility and rebound characteristics suited to sealing and cushioning tasks.

The product is provided as a 25 m length to support multiple applications without frequent replenishment.

It meets ISO 10993-10 and ISO 10993-5 assessments relevant to irritation and cytotoxicity evaluations.

It is supplied double-ended so adhesive coats both faces, enabling direct bonding between two substrates.
