kitchen door in polymeric foil

Talking of polymer, in the furniture industry, we refer to a coating of PVC or PET used for the production of panels or doors.

There are various types of polymeric sheets.  The most widespread  type , however,  is PVC,  with a thickness of 0.3 to 0.9 mm.  Polymeric sheets  are available either in monochrome shades or imitation  of  wood

Polymer  is different from plastic products, because the polymeric sheets can be deformed and ‘ironed’, while thermoplastics,
even though  they become flexible,  they cannot be ‘ironed’. This is the main  reason  why they are used in three dimensional overlays.

To produce a kitchen door, an MDF  base is required (as  its surface is smoother and more uniform than chipboard) . That gets  coated with  glue (usually PUR or vinyl) and  a  polymer sheet  is applied and stretched  on top of it . The sheet is then compressed in a membrane press  which heats  it and expels   the excess air and thus occurs the adhesion of the sheet.  As a final stage, the door is cleared of excess cover material.

PVC has a lower resistance to scratches  compared to laminate  and for this reason it is not used for worktops,  only for vertical surfaces.  It’s scratch resistance is similar to that of natural wood (when  referring to a wood imitation product) and it’s significantly  cheaper. Note that  it can be painted over using the same varnishes used for wooden surfaces.

If PVC is burned , can release dioxin  and chlorine compounds, thermoplastic sheets  are used instead, as PET  is considered more environmentally friendly.
