Poron® Urethane Gaskets

We supply a wide range of Poron® Urethane sponge gaskets, cut from roll stock material in house to suit customer requirements.

Poron® Urethane is a closed cell sponge material that is manufactured in black. The main properties of Poron® Urethane are its excellent compression set and deflection characteristics; this means that Poron® Urethane gaskets keep their shape well. In addition to this, Poron® Urethane also has low outgassing characteristics and is UV stable, making it ideal for outdoor use.

Poron® Urethane is UL certified for use as gasket material (ULJMST2) and for flammability (ULHBF). We have the facilities to manufacture a wide range of Poron® sponge gaskets from roll stock material. In order to allow for quick turnover times, we keep certain grades of Poron® Urethane as a stock material at all times.
