ETA certification: AF Sleeve, fire-rated wrap for combustible pipe penetrations

We are pleased to inform you that AF Systems has obtained the ETA certification for AF SLEEVE, our solution for sealing pipe passages made of combustible plastic materials;

AF SLEEVE is an intumescent preformed sheath consisting of a material with high thermo-expansion power which, under the action of heat, guarantees the sealing of the passing pipe by means of the complete obstruction of the same.

The fire resistance is EI 180 with rigid wall and slab according to EN 13501-2. The tests have been carried out according to EN 1366-3.

When exposed to a temperature above 180°C, it expands by blocking fumes and flames and provides the necessary thermal insulation to achieve EI180 classification.

The product is marketed for the protection of plastic pipes (PVC, PP, HDPE, PE, ABS, SAN+PVC) of diameters between 30mm and 160mm.

AF SLEEVE meets the requirements for use of category Y2, with a durability certificate that ensures its suitability in temperatures between -20° and 70°C.
