Lydall - Model PPS -High Temperature Fiber

PPS is a high temperature fiber, up to 180°C, with excellent chemical resistance except for oxidizing agents such as NO2 and Oxygen itself. It has very good acid resistance and this, together with a good thermal resistance has led to wide acceptance in combustion processes. The fiber is actually 30% sulfur by weight and it has a very high limiting oxygen index (34) when compared with the volume fibers.
