Propad, the light and warm polypropylene padding

Polypropylene fiber has the lowest coefficient of heat transfer and the greatest insu­lating power compared to all the other textile fibers normally used for insulations. In addition, it is from 20 to 30% lighter than those fibers, so that the garments made of polypropylene are warmer and lighter.


  • Low ability to absorb liquids: absorption coefficient of liquids residual water content expressed as a percentage of the weight of the dry product.
  • High vapour permeability: the high value of permeability ensures the rapid transfer of humidity through the insulation and thus the maximum transpiration.

  • Low heat transfer coefficient: The low value of the thermal transfer coefficient reduces (compared with other fibers) the loss of heat produced by the body when it is in a cold environment.
  • High insulating power: The insulating power depends on the amount of air trapped in the fiber: polypropylene has the capacity of retaining heat similar to wool.

  • Lightness: Polypropylene has a specific weight that is lower than other textile fibres.
