Tosaf Color Service’s colour, functional and combination masterbatches for POM are now based on particularly low-emission carrier materials.

Tosaf optimises carrier material for low-emission POM masterbatches
In addition, the pigments have been optimally selected with regard to their effectiveness. As a result, the low emission data of the starting material – depending on the POM type – are almost fully retained, even after colouring and compounding. The new masterbatches thus help ensure compliance with the strict specifications of the automotive industry for moulded parts, and also with the requirements regarding personnel safety.
The emission-optimised masterbatches are suitable for all POM grades. At the customer's request, ongoing applications can also be switched to the new technology.
Tests carried out at an independent institute show the efficiency of the adopted measures, based on the example of a conventional, low-emission POM grade, to which a combination masterbatch was added. By switching from the conventional masterbatch to one with optimised colour pigment and carrier material, the formaldehyde release was reduced from non-permitted 8.8ppm to a very good rate of below 6ppm.
Sales Manager Andreas Kruschinski said: "With the consistently high batch-to-batch quality level of our masterbatches, and because of their ease of handling, our new low-emission grades are gaining a growing number of authorisations and are also registering the first series applications for car interiors. SCHAUENBURG Industrietechnik GmbH is one of our pilot customers in this area. In addition, we are experiencing growing demand in all typical POM applications in a wide variety of industries."
The portfolio of low-emission POM masterbatches ranges from grades in standard and customised colours through functional versions, e.g. with lubricants, UV or heat stabilisers, to combination grades with or without a colour component. Typical applications beyond automotive interior/exterior parts and conveyor technology include components for office and entertainment electronics, as well as white goods including small and large kitchen devices.
