Self Adhesive Foam Rubber 80Kg/m3 H 150 cm (per meter)

Technical data sheet: 'Flexible polyurethane foam'

The mass of any PUE sample is homogeneous and made up of a uniform plastic polymer called polyurethane.

So there are no other foreign substances present. The raw materials from which we start to obtain polyurethane, by making the various components react with each other, are:

- Polyol Polyether (basic raw material).
- TDI Toluendiisocyanate (co-reactant with polyol and water).
- Water (expanding). Silicone oil (surfactant).
- Tertiary amines (catalysts for the expansion reaction).
- Stannous octoate (catalyst for the polymerization reaction).
- Antioxidant (internal yellowing regulator due to exothermic reaction).
- Reactive dyes (only for colored foams).
- Anti-flame (additive inhibiting the spread of flame).

These ingredients are no longer found in the final polymer, except for the flame retardant, which, not being reactive, is incorporated into the solid polyurethane matrix as it is.

Over time, the product tends to normal and inevitable yellowing
