1.1 COMPOSITION

Typical: structural concrete

The Sintofoil TPO/FPA (Flexible Polypropylene Alloy) membrane is produced by extrusion of granules resulting from the incorporation of uncured ethylene propylene rubber into a propylene matrix. The sheet is made of one or several layers made of different grades and thickness.

The completely integrated rubber component gives the Sintofoil materials a combination of mechanical toughness and high flexibility that is achieved without the use of plasticisers.The result is a material that is ideal for demanding applications in the construction industry where long-term waterproofing performance is required. In areas like roofing and lining, Sintofoil materials now offer considerable cost-performance benefits when compared to conventional and other synthetic materials.

1.2 PACKAGING

Sintofoil membranes are manufactured in standard roll sizes 2.10 m x 25 m and 1.50 m x 30 m, 1.2 mm thick. Other sizes and thickness are available on special order.

Each roll is wrapped in a translucent plastic sheet. The rolls are packaged on stackable pallets, 18 ea rolls/pallet (ST and RG types) and 14 ea rolls/pallet (FB type).

1.3 WELDABILITY

The Sintofoil sheet offers an excellent margin of safety in this respect,since the temperature range over which reliable seams can be produced is broader than for most other synthetic materials.The typical welding conditions are as follows:

1.4 WEATHERING

Due to the intrinsic cleanliness of its chemical structure which does not include plasticisers, the Sintofoil membrane is much less affected by dust and air borne pollutants than traditional membranes and can be welded after a long period of outdoor exposure. However, the experience has proven that welding weathered membrane is eased when the specific procedure as developed by Imper Italia / Rubberfuse Division is followed (see 3.6 and 4.4).
