To illustrate FireShield® behaviour, tests were carried out with pultruded sections made into two open box shapes, one of which was protected with FireShield®.
A short video has been prepared from the continuous filming of the test.
It was of particular interest that the ∆T across the char layer of the protected sections showed no change over the 30 minutes of the burn, indicating that the char itself was not reduced or ablated by the propane burner, during that time.
