Desmopan® and Platilon® TPUs produce leading-edge roofing membranes

Roofing membranes serve an essential purpose: standing up to the elements. By creating a watertight covering, membranes keep a building’s interior—and the precious items it holds—safe and dry. Thermoplastic polyurethanes (TPU) are proven and reliable in this application, giving roofers peace of mind.

Keeping the moisture away with Desmopan® TPU

Covestro offers several Desmopan® TPU resin grades for roofing membranes. This versatile material, already known for its abrasion and mechanical resistance, possesses another property that is especially relevant for roofing membranes: Water Vapor Transmission Rate (MVTR) performance. Due to the combination of the inherent mechanical resistance and the high MVTR, Desmopan® TPU creates a moisture barrier that is superior to other commonly used materials, such as polyolefin.

Roofing membranes with TPU offer moisture control and high mechanical resistance

Customized solution with Platilon® TPU films 

Drawing on industry experience, Covestro is helping to meet industry needs by making continuous improvements to Platilon® TPU films for roofing membranes. This material solution offers desirable properties that can be customized for roofing applications, including high abrasion resistance, high tear resistance, even at thin thickness, and excellent weathering and UV resistance. The material is also known for its breathability, which means it is watertight and offers a high MVTR.

Roofers who utilize TPU roofing membranes have peace of mind knowing they are using a reliable solution that has been proven for about 20 years.
