It offers high resiliency, ability to withstand several cycles of loading/unloading without breaking, good chemical resistance and good thermo-mechanical properties. Expancel® 920 WUF 40 provides low density, controlled expansion and uniform cells, reduction of weight, easy application, very good sanding properties and low after-sinking and shrinkage. It improves shock-, vibration- and sound absorption, thermo-insulation and recovery after elongation and compression.
