IPS product data Sintofoil ST Membrane

Sintofoil ST Membrane

1. DESCRIPTION

TPO/FPA (Flexible Polypropylene Alloy) membrane produced by extrusion of granules resulting from the incorporation of ethylene propylene rubber into a propylene matrix together with other additives as appropriate to the type of membrane.

3. FIELDS OF APPLICATION

Roofing of non-accessible roofs on various substrates: concrete, steeldeck and wood.
Waterproofing of parking decks and garden roofs.
Basement tanking and tunnel waterproofing.
Lining of ponds,canals,reservoirs and landfills.

4. CHEMICAL RESISTANCE

Sintofoil membrane is of polyolefinic nature i.e. has an intrinsic chemical stability.This implies the membrane can be in contact with many substances of either acid or basic type while maintaining its properties.Long term exposure to highly aggressive agents,especially at elevated temperature, requires a specific case by case evaluation.

5. APPLICATION

Sintofoil membranes are installed in compliance with the specifications and details described in the technical manual as published by Imper Italia / Rubberfuse Division.
Roofing and waterproofing systems using Sintofoil membranes are installed by applicators trained and approved by the Technical Department of Imper Italia / Rubberfuse Division.
