Patinna-HDF High Density was developed for use
where physical property integrity and surface finish
are important. The average density of more than 820
kg/m3 (51 lb/ft3) ensures high
core strength and face density.
Patinna-HDF High Density can substitute veneer cross bands in hardwood
veneered plywoods by providing a superior smooth surface
to reduce potential surface defects such as telegraphing
of expensive, thin surface veneers. Its high internal
bond is able to withstand most hot-press conditions.
The high quality
surface of Patinna-HDF High Density also makes an excellent
white board substrate allowing application of paint
or laminate. In the electronics industry, the hard uniform
properties of our 2.5mm (0.10 in) product perform well
as backer board in the printed circuit board (PCB) manufacturing
process.
As with all our
products, you can also request Pure FSC (Forestry
Standards Certification) wood be used to make your high
density panel.
