tesa® 88665 – High-Performance Double-Sided Tape for Silicone and Critical Surface Bonding

tesa® 88665 is a transparent, double-sided tape engineered with a PET backing, combining a silicone adhesive on one side and a modified acrylic adhesive on the other. This unique design makes it the perfect solution for bonding silicone materials to non-silicone substrates. With a thickness of 115 µm, tesa® 88665 is ideal for applications requiring strong adhesion and durability, even in demanding environmental conditions.

The silicone adhesive provides exceptional bonding strength to silicone-containing surfaces, while the acrylic adhesive offers versatile performance on various other materials, such as PP and PE. Its advanced design ensures excellent handling during converting processes, making it an essential choice for industrial applications.

Key Features:

Outstanding silicone adhesive properties for bonding silicone and silicone-containing substrates.
Versatile acrylic adhesive ensures strong bonding on a wide range of surfaces.
Excellent performance under demanding environmental conditions.
Superior handling and processing performance in converting applications.

Applications:

Laminating silicone foam.
Mounting silicone rubber components (e.g., rubber feet, phone cases, keypads, gaskets).
Mounting on critical surfaces such as PP and PE.
