Glow-in-the-dark masterbatch

Why masterbatch?

Adding powdered pigment directly to plastics processing requires good dosing and dispersion equipment – and dust control when handling large quantities of powder. A masterbatch already contains the glow pigment in concentrated, evenly distributed form in a carrier polymer. In your own process it is simply mixed with the base material at the specified ratio.

How your masterbatch is created

1. Capturing requirements: base polymer, process and processing temperature, desired glow colour and brightness, wall thickness, colouring of the end product, planned let-down ratio.
2. Configuring: pigment, particle size and concentration are matched to your let-down ratio and process.
3. Assessing and evaluating: together we assess the result – ideally through sampling in your production.
4. Producing: production is also possible in Germany.

What matters technically

• Untinted pigments only. Compounding, injection moulding and extrusion are above 150 °C – only untinted pigments with a light, whitish daylight colour are suitable here, such as natural green, blue-green and untinted blue.
• Even distribution. An even glow requires even dispersion – which is exactly the advantage of masterbatch.
• Light, transparent plastic. Transparent or light polymers let light reach the pigment and get back out; dark colouring reduces brightness.
• Concentration and let-down. The guide value for the finished part is 15–20 % pigment relative to the carrier. How concentrated the masterbatch needs to be follows from your let-down ratio.
