Polypropylene

Polypropylene honeycomb is available in different honeycomb shapes: with Non-woven fabric (TNT), without Non-woven fabric and covered by Non-woven fabric with an additional thermowelded plastic film

Polypropylene is used as core for honeycomb panels. Polypropylene honeycomb is also used as a filter media for corrosive gases. In aggressive environments, it is particularly reliable in terms of quality and resistance to chemicals. In addition, combined with TNT, it can be used as a support for waterjet table tops.

Without TNT, polypropylene is an excellent shock absorber because it absorbs kinetic energy.
Polypropylene honeycomb with non-woven or technical fabrics is a solution for sandwich 
and composite panels. In this case, two covering skins are applied on both sides of the sheet
 

Technical features

Polypropylene honeycomb is available in different types:

  • in honeycomb form without non-woven fabric (PP 8.80 );
  • in honeycomb form covered with a small fleece heat-sealed on both outer surfaces (PP8-80 T30, PP8-120T30) called non-woven fabric (TNT);
  • in honeycomb form covered with non-woven fabric plus an additional plastic film (PP8-80 T30F75)

IMPORTANT

To allow us to offer you a panel with particular finishes or colors without minimal pigment variations, it is recommended to place an overall order , so that we can plan the production with the rolling mills that will carry out the painting of the sheets in a batch.
