ThermHex Polypropylene (PP) Honeycomb
Polypropylene (PP) honeycomb is a strong but flexible lightweight material which provides efficient and optimum mechanical performance in composite sandwich structures.
ThermHex Waben GmbH manufactures a broad range of high quality, durable and economic core products with a standard density of 80 kilogram per cubic meter (5.0 Lbs / ft³).
Currently honeycomb cores are available from 3 mm to 30 mm thickness. Besides, the cell width varies from minimally 3 mm to a maximum of 9.6 mm. Standard thicknesses are 3.5, 8, 10, 15, 20, 23 and 28 mm.
This new type of sandwich material is produced from a single Polypropylene film in a continuous thermoforming, folding and bonding operation which also includes lamination of non-woven layers and barrier films onto the core.
ThermHex honeycomb core, compared with other material in the market, delivers an exceptional surface quality in sandwich components even with very thin skin material layers. An excellent bond between core and GRP skin is guaranteed. ThermHex material comes in unrivalled consistent, weld-free panels of a maximum width of up to 1.400 mm. Standard panel length is 2.400 mm, while longer panels are available upon request.
