Matrix Polymers Polypropylene Development – A New Way Forward
Partnered with the well-established rotomoulder Amber Plastics, Matrix has worked closely with Dennis Eagle in order to provide them with an engineered solution to one of their demanding application: a rotomoulded header tank for the cooling circuit of the Phoenix 2 (a body work machine). The proposed material which would have fulfilled the header tank requirements, as resistant to chemical attack, vibration, high temperature, good impact…, was Revolve S-TeQ PP 35 N.
It was decided to measure the temperature insight and outside the tank. Real temperature data inside and outside an existing header tank were monitored and recorded during standard working time. This measurement has been proved essential in order to identify the most suitable material for the application. An extract from the measurements are plotted and illustrated in figure 1.

Figure 2 - Header tank |
Figure 2 illustrates the point where the header tank is located on the body work machine. It is also possible to notice the location of the thermocouples. It was understood that the highest temperature recorded was between 80 and 90 °C. Therefore the proposed material was confirmed as Revolve S-TeQ PP 35 N. Revolve S-TeQ PP 35 N was moulded at Amber in accordance to the Matrix guidelines. The header tank then underwent to a set of tests in order to confirm the material and the rotomoulded item were fulfilling the Dennis Eagle requirements.

Figure 3 - ARM impact test comparison |
An impact test based on the falling dart in line with the ARM International guideline was carried out. The specimens were kept in a controlled temperature room at 23 °C for 24 hours before being impacted.
