Fitherm NP is an – phosphate based product – intumescent material that foams up pressure-free, forming a firm and heat-resistant foam in case of fire. Fitherm NP fills gaps and cavities and builds up a very effective barrier against fire and smoke. Fitherm NP is a halogen free product. It can be laminated with a self-adhesive tape on one side for fixing.

- Fitherm NP (phosphate based product) is developed for a wide range of applications where an intumescent material is necessary to maintain the system integrity and insulation in case of fire. These systems are for example:
- Fire protection doors from wood, steel or aluminium
- Glazing elements
- Component joints
- Pipe penetrations and cable transit systems
Fitherm NP should be stored under room conditions (best above 10°C). During handling and processing the wearing of protective gloves is recommended.
Fitherm NP is available as flexible rolls in the following standard dimensions:
Thickness: 1mm,1.5mm or 2mm;
Width: 10mm, 15mm and 20mm;
Lenght: 25 meter with or without self- adhesive backing, Other sizes on request.
