Through-dyed laminates

Laminate sheets are made up of paper layers, which are impregnated with thermosetting resins. Unlike conventional laminate sheets, when producing through colour laminate, only paper with identical colours are used for the core and surface. These are impregnated with clear melamine resin and are pressed together at high pressure of over 50 bar and temperatures of over 120 degrees Celsius. The resulting laminate is used as surface material. It is characterised by its homogeneous colour and is extremely robust and resistant.

The European standard EN 438 - Part 9 defines the performance requirements for alternative core laminates, as they are called in the standard, for indoor applications.

By the way: through-dyed Duropal SolidColor laminate sheets are not to be confused with Duropal compact laminates.  Duropal SolidColor has the same colour as the decorative surface and, thanks to its sanded back, can also be used with different core materials. Duropal HPL Compact on the other hand, has a decorative surface on both sides, a black, grey or white core and is available with a wide range of decorative surfaces.

Duropal SolidColor is an attractive material for surface and edge applications, with the high performance characteristics of Duropal HPL. The homogeneously coloured core laminate sheets offer the freedom of monochrome design of furniture and interior fitting without visible butt edges and joints. They can be used both horizontally and vertically and are suitable even for highly frequented areas.

HPL with coloured core from Pfleiderer is

• resistant to abrasion, impact and scratches
• stain resistant and disinfectable
• easy to clean
• food safe
• antimicrobial and hygienic
• non-fading

HPL with a coloured core is always produced in sheets and is therefore available as a full-size material for custom cutting. The back of the panels can be glued, allowing them to be bonded to suitable wood-based panel cores, usually MDF or particleboard.

A completely symmetrical lay-up is required to produce dimensionally stable flat-bonded elements, i.e. exactly the same laminate material must be used on the front and back. This has already been taken into account in our Duropal SolidColor flat-bonded elements: you will receive pre-finished panel materials with symmetrical lay-up directly from the factory.

Colour core laminates are used not only as a surface material but also as an edge material: thanks to the perfectly matched HPL core, a smooth transition between all surfaces is achieved on chamfering the edge - for a monolithic look with no visible joints or edges.

The handling, storage and use of coloured core laminates always requires special care, as they are not only harder but also slightly more brittle. Please refer to our Instructions for Use and read the information sheets issued by the proHPL specialists (www.pro-hpl.org).

In addition to the homogeneously through-dyed Duropal SolidColor laminate sheets, the Pfleiderer product range also includes other panel materials with coloured cores:

• Robust, moisture-resistant compact laminates with decorative surface and black, grey or white through-dyed core
• Black through-dyed medium-density fibreboard (MDF), optionally with or without surface facing:
  • raw board
  • lacquered boards with decorative surface in super matt and mirror gloss finish
  • decorative melamine resin panel
  • flat-bonded board with hardwearing HPL covering

All through-dyed sheet materials from Pfleiderer are available in large, economical sizes and can be cut to size as needed in the further processing.
