Additional Information
Fabrication
This range of material provides versatile, self-coloured material with a high strength to weight ratio that can be easily worked with using basic wood and metal working tools and easily transported due to its lightweight nature.
Cutting – using a cutting knife or a straight, finely serrated blade mounted on a hand-saw, band saw, disc (circular) saw or jigsaw. Sheets exceeding 3mm must be sawn. It is also suitable for sawing, drilling, milling, routing and guillotining.
Fastening – Panels can be fixed to supporting structures using screws, rivets, nails and adhesive.
Bonding – can be bonded to itself or other materials.
Drilling – can be drilled using any conventional drill.
Welding – either by hot air welding or butt welding.
Die Cutting – flat shapes with complex outlines can be die cut from thinner sheets.
Weather & UV Resistance
Coloured foam PVC can be used for a number of short term exterior applications. Black, white and grey have the greatest colour retention while that of red and yellow is lesser. Applications most shaded from direct sunlight will retain colour longest. Climate, location and project specifications should be taken into account when considering this material for outdoor projects.
Installation
It is important to make allowances for thermal movement (a 2440mm long panel will expand by 3.32mm as the temperature rises from 20°C to 40°C).
Colour Panel Orientation
The refractive index of panels viewed in the line of extrusion can vary to that across the line of extrusion. It’s important to assemble the panels in the same direction of orientation.
Printing Processes
Screen printing and direct to substrate digital printing.
Thermoforming
Components which are relatively simple and shallow in form are thermoformable from this material. An elastic state is reached between the temperature range 115-130ºC.
Folding - can be folded on a simple jig fitted with a forming tool having a radius of about two and a half times the sheet thickness.
Draping – by softening a panel to an elastic state, draping over an appropriately shaped pattern and retaining it until cooled and rigid.
Chemical Resistance
This material is resistant to most chemicals and atmospheric pollutants. Contact with solvents and wet wood preservatives must be avoided.
