Integrated Intumescent technology (IIT)
A new way to look at fire protection
IIT was designed to remove the inherent flaws in conventional intumescent technology and at the same time build on the strengths.
In a conventional intumescent material a number of components have to react before the substrate can be protected from the heat.
These components are:
- A phophorus source to act as a catalyst typically ammonium polyphosphate
- A carbonific source to act as a char former typically pentaerythritol
- A gas source usually nitrogenous gas and typically produced by melamine
The IIT technology works on the theory that if this reaction has already partially occured prior to the fire and the components are molecularly bonded together then they can react at a lower temperature and an earlier point in the fire thereby protecting the substrate earlier and allowing it to maintain its structual integrity longer.
There are two generations of IIT technology:
- The first was developed in 1992 and was called IIP (Intrinsically Intumescent Polymers). This is licensed to Chemische Fabrik Budenheim. They can be contacted here for further information on this technology.
- The second generation is known as Phosphorus Rich Polymers (PRP) and Mixed Intumescent Polymeric Salts (MIPS). PD has no responsibility for the commercialisation of these products.
