POLYDAN 180-48 P ELAST

About this product

Bituminous SBS modified membrane reinforced with a heavy non-woven polyester felt.

Finished in a quick-melt thermofusible film.

Designed for torch-applied applications and Safe2Torch details using hot-air.

Underlay sheet (first and second) of multi-layer membranes with mineral self-protection for the waterproofing of railway decks (System II).

Underlay for self-protected double-layer bonded membranes.

Bottom or top sheet in two-ply membranes with heavy bonded protection).

Bottom or top sheet in two-ply membranes with heavy unbonded or floating protection.

Single-layer membrane for waterproofing roofs with heavy bonded protection.

Single-layer membrane for waterproofing of heavy unbonded or floating roofs with heavy protection.

Good performance in nailed systems.

It has a heavy polyester felt reinforcement (heavier than LBM-(SBS)-40-FP).

It has a nominal mass of 4.8 kg/m², which is higher than the 4.0 kg/m² of LBM-40-FP). The higher mass of plastomeric bitumen increases the durability of the waterproofing and makes it easier to lay the sheet.

The higher grammage of the polyester reinforcement gives the sheet higher mechanical performance in tensile, static and dynamic piercing and tearing.

A membrane for instances where high waterproofing performance is required.

The sheet, being made of a bitumen mastic modified with SBS-type elastomeric polymers, substantially improves other bituminous mastics, providing much better performance in terms of reaction at high and low temperatures, elasticity and resistance to ageing, which leads to greater durability of the sheet and greater safety of the waterproofing membrane.

Has good piercing protection from possible mechanical damage, derived from the occasional pedestrian traffic typical of flat roofs.
