New chemical foaming agent masterbatches for PVC foam core pipes
11.09.2025
Tornesch/Germany, September 2025 – For many years TRAMACO has been a major supplier of chemical foaming agents to the foam core pipe industry. A wide range of different products has allowed TRAMACO to fulfil multiple customer requirements resulting from their individual formulations and processing setups.
Building on this long-standing experience and in view of the changes in production equipment and formulations that have occurred in recent years TRAMACO has developed a new line of chemical foaming agents for this industry.
A modified production technology allows for a compact micro-granule that is free-flowing and can easily be conveyed and dosed automatically, providing improved mixing with the matrix polymer. A new carrier system, developed for minimum rheological effects, gives a stable granule that melts down fast in the extruder and provides optimum dispersion of the foaming agent in the PVC melt.
In this new product line TRAMACO has included existing, long proven foaming agent chemistry and new chemistries fitting to the requirements of new formulations.
Individual, custom-tailored solutions are also available in this new product line.
