Adhesive tapes

A professional adhesive tape is a bonding solution made up of a backing coated with an adhesive mass on one or both sides. Depending on its design, it can be used for packaging, masking, protection, fixing, insulation, or assembling materials. Its performance depends notably on its backing, its adhesive, and the conditions under which it is applied.

The choice mainly depends on the materials to be bonded, the level of adhesion required, the duration of the bond, and the conditions of use. It is also important to consider temperature, humidity, mechanical stresses, and potential exposure to UV or chemicals. The dimensions of the roll and the method of application should also be checked.

Depending on its design, it can be used for packaging, masking, protection, fixing, insulation, or assembling materials. Its performance depends notably on its backing, its adhesive, and the conditions under which it is applied.

The backing should be selected according to the intended use. Paper is particularly suitable for masking, while polyester or polyimide films are used for more technical applications. Foam backings help to compensate for certain irregularities, while fabric, PTFE, or fiberglass tapes meet specific needs for strength, protection, or insulation.

An acrylic adhesive generally offers good resistance to ageing, UV and temperature variations. A rubber adhesive often provides quick initial adhesion on many substrates. A silicone adhesive is more suitable for high temperatures and certain difficult surfaces. The choice therefore depends on the substrate, the environment, and the expected performance.

It is necessary to consider the material, roughness, cleanliness, and surface energy of the material. A smooth and clean surface generally facilitates adhesion, while a dusty, greasy, uneven, or difficult-to-bond substrate may require a specific adhesive. Conducting a test allows for checking the grip, performance, and removal of the tape.

High-temperature applications require a tape specifically designed to maintain its adhesion and properties under the expected conditions. Depending on the temperature, duration of exposure, and the process used, it may be necessary to choose a substrate made of polyester, polyimide, PTFE, or fiberglass with an appropriate adhesive. The stated resistance should always be compared to the actual stresses of the application.

A permanent adhesive is designed to provide a durable bond and resist peeling. A repositionable tape can be moved or adjusted during application before reaching its final adhesion level. A temporary adhesive is intended to be removed after a limited duration, particularly for masking, protection, or temporary holding.

Yes, some adhesive tapes can be cut, shortened or transformed into a width suitable for the application. The feasibility depends on the material, thickness, diameter of the roll and the requested width. DERFI can also study the need and carry out tests to verify the compatibility of the tape with the materials and the conditions of use.
