Non-woven adhesive tapes

A non-woven double-sided adhesive tape has a sticky surface on each of its sides and a soft central backing made of non-woven fibres. It allows for the discreet assembly of two materials, without liquid glue or visible mechanical fastening. It is particularly used for bonding, mounting, laminating, and double-sided sticking.

The non-woven backing provides flexibility and allows the tape to better conform to the materials. It facilitates achieving a uniform contact between the two surfaces, even when they are slightly textured or soft. Its low thickness also allows for clean and discreet assemblies.

A non-woven double-sided tape is generally more flexible and conformable. It is particularly suitable for papers, cartons, foams, and slightly irregular materials. A PET double-sided tape has a more stable and less deformable structure, suitable for assemblies requiring greater dimensional precision or mechanical strength.

A non-woven double-sided tape remains thin and is suitable for lightweight assemblies requiring little thickness. A foam adhesive tape is thicker and allows for compensating for greater irregularities or level differences. It can also help distribute stresses and dampen certain vibrations.

According to its formulation, a non-woven double-sided adhesive tape can be used on paper, cardboard, foams, textiles, films, lightweight plastics, and various technical substrates. However, compatibility depends on the roughness, cleanliness, and surface energy of the materials to be bonded.

Its flexible structure allows it to adapt to slightly uneven or textured surfaces. However, it cannot compensate for significant dips or large differences in level. For very rough or deformed materials, a thicker foam tape may provide better contact between the surfaces.

The choice depends on the materials to be bonded, the level of adhesion required, the desired thickness, and the mechanical or thermal constraints. It is also important to consider the duration of adhesion, the temperature of use, and the method of application. DERFI can conduct tests to propose a non-woven tape suitable for bonding, laminating, or the desired assembly.
