Textiles with schoeller®-PCM™ contain innumerable tiny microcapsules filled with Phase Change Materials (PCM). These microcapsules react to temperature differences by altering their aggregate condition from solid to liquid and vice-versa. The Phase Change Material in the microcapsules has been set to a particular temperature range. If the body temperature or the outside temperature rises, the excess warmth is stored. When the temperature drops, the previously-stored warmth is released again.

schoeller®-PCM™ actively balances out temperatures which are too high or too low and thus always ensure the wearer's personal comfort climate. schoeller®-PCM™ supports the normal insulation pro perties of a garment. Even at very low prevailing temperatures and at times of inactivity, the body is kept warm over a considerably longer period. In the reverse case, in warmer conditions the body is cooled and overheating prevented during physical exertion.
