An innovation in fire protection
Technical properties
Our material PT FirstOne is a non-combustible, extremely pressure-resistant and thermally insulating construction fiber material that is used to manufacture three-dimensional and non-combustible components.
PT FirstOne, PTFO for short, fulfills relevant fire protection requirements across all industries and has diverse, unique and irreplaceable properties.
PT FirstOne is based on an inorganic material composition consisting of finely granulated minerals and a phosphoric acid preparation. This conglomerate, combined with various fiber and fabric mats, ultimately forms our inert, non-combustible construction fiber material. PTFO thus transforms into an inert, solid substance when exothermic.
PT FirstOne has all the advantages of classic fiber composites, but also has other unique and irreplaceable benefits:
Non-flammable at up to > 2500°C
Thermal insulation in the high temperature range depending on the material thickness (>12 mm = F30 - F240)
No smoke development
No decomposition or liquid dripping of PTFO in the event of fire
Our material maintains complete integrity when exposed to fire for hours at temperatures above 1500°C
