Pyrostrip Interdens (10mm x 2mm x 1m Strip) 

Pyrostrip Interdens Intumescent System

Size: 2mm Width 

Roll Length: 1m Strip

Pyrostrip Interdens is an advanced phosphate-based (MAP) multi-component intumescent system specifically engineered to provide a minimum of 30 minutes of fire protection for a wide range of fire-resistant glass and other structural applications.

Key Features:

1. Intumescent Properties: Upon exposure to heat, Pyrostrip Interdens' components undergo a chemical reaction that forms a soft char. This char expands up to 40 times its original volume, effectively sealing any gaps that may form during a fire. This expansion not only prevents the passage of flames and smoke but also insulates and protects timber substrates from high temperatures.

2. Proven Fire Resistance: Pyrostrip Interdens has been rigorously tested and proven to provide more than 30 minutes of fire resistance, making it a reliable choice for critical fire safety applications.

3. Aesthetic and Practical Options: Pyrostrip Interdens is available in a variety of finishes, including white, red, black, and brown, allowing for aesthetic integration into various design schemes. It is supplied in sheet form and can be cut to the required size or length, offering flexibility in installation.

4. Ease of Installation: For added convenience, Pyrostrip Interdens can be supplied with a self-adhesive backing, simplifying the fixing process. This feature is particularly useful in applications requiring quick and secure installation.

5. Flexibility and Versatility: The system remains completely flexible when cold, facilitating easy handling and application. It is available in standard thicknesses of Type 5 (0.6mm), Type 15 (1mm), and Type 36 (2mm), catering to a range of protective needs.

6. Applications: Pyrostrip Interdens is suitable for use with fire-resistant glass and other applications where effective gap sealing and substrate protection are critical. Its multi-component design ensures comprehensive fire protection and structural integrity during fire incidents.

Overall, Pyrostrip Interdens is a high-performance intumescent system that combines chemical ingenuity with practical design, offering robust fire protection and ease of use in various architectural and structural applications.
