Sealing tapes

The category "Sealing Tapes" includes adhesives designed to create a barrier against water, humidity, air, dust, or certain external agents. Used alone or in conjunction with an assembly, they help to strengthen the protection of components, surfaces, or systems subjected to environmental stresses.

These tapes improve the durability of assemblies and the reliability of connections by creating a protective interface between surfaces. They are particularly useful in technical, industrial, or outdoor applications requiring protection, performance maintenance, and reduced water ingress.

Why choose a sealing tape?

A sealing tape, also known as sealing adhesive, protective tape or technical joint tape depending on the usage, is used to protect, insulate or reinforce an area to limit the infiltration of water, air, dust, moisture or external agents. It helps to improve the reliability of assemblies and the durability of surfaces exposed to environmental constraints.

This type of adhesive tape is particularly suitable for technical, industrial, outdoor, maintenance or construction applications. It secures a connection between two surfaces, protects a sensitive joint or reinforces an area subject to the risk of infiltration or loss of sealing.

A solution suitable for technical connections and protections

Sealing tapes can be used on different substrates depending on the application: films, membranes, sleeves, panels, metal surfaces, plastics, construction materials or technical components. They allow for clean, quick and effective connections, while providing a protective barrier suitable for the constraints of the job.

Depending on the needs, it is possible to choose a PTFE tape, a Teflon® tape, a high-temperature adhesive, a silicone adhesive tape or a technical solution suitable for exposed areas. Each tape meets specific constraints of adhesion, resistance, temperature, exposure duration and compatibility with the substrate.

Protection, resistance and reliability

A well-chosen sealing tape ensures a consistent application, good hold and long-lasting protection of sensitive areas. It helps to limit infiltrations, secure connections and maintain the performance of installations over time.

It also saves time on installation, repair or maintenance operations, while ensuring a clean and professional finish. In an industrial or technical environment, choosing a suitable sealing adhesive enhances the safety of assemblies and reduces risks associated with external constraints.

DERFI support

DERFI offers sealing tapes, PTFE tapes, Teflon® tapes, technical adhesives, and protective solutions tailored to the needs of professionals in construction, industry, maintenance, and technical applications.

DERFI's support helps to choose the most suitable tape according to the substrate, exposure constraints, the expected level of sealing, the temperature of use, and the technical requirements of your application. Each solution is selected to ensure reliable protection, effective application, and improved durability of assemblies.
