Solutions for E-mobility Requirements through Polymer Additives

The EU action plan coming from the Paris climate agree­ment aims to decrease global green­house gas emis­sions, the chief one of which is CO2. A major contrib­utor of CO2 is the auto­motive internal combus­tion engine. The car industry has taken on the chal­lenge by light weighting their products and commen­cing a shift, through E-mobility, towards hybrid and battery elec­trical vehicles. Both light weighting and hybrid­iz­a­tion see the use of smaller engines which tend to run at much higher temper­at­ures. This makes protec­tion of their poly­meric compon­ents, normally poly­amide based, much more complic­ated. Elec­trical vehicles, on the other hand, through their high elec­tric current loads create different diffi­culties. With its new products BRUG­GOLEN® TP-H1804, BRUG­GOLEN® TP-H1805 and BRUG­GOLEN® TP-H2062 the Polymer Addit­ives busi­ness of Bruegge­mann has risen to meet these chal­lenges.

Until recently under-the-hood plastics parts could be satis­fact­orily stabil­ized by addit­ives that func­tioned at peak temper­at­ures of up to 180°C. Supplying anti-oxid­ants here is a main­stay of Bruegge­manns busi­ness. Today’s smaller but more powerful engines, through their use of turbochar­gers, have seen compon­ents exposed to 210°C peak levels. In order to meet these require­ments Bruegge­mann has developed BRUG­GOLEN® TP-H1804 and BRUG­GOLEN® TP-H1805. The former bridges the gap between 180°C and 200°C whilst the latter allows a typical poly­amide component to be stabil­ized above 200°C. Prior to these products, the higher temper­at­ures could only be met with polymer modi­fic­a­tions such as poly­phtal­am­ides. These are not only much more expensive but were also only supplied by the resin suppliers them­selves and there­fore very often not avail­able to our main customer base, the inde­pendent plastics compounder.

The trans­ition to e-mobility brings with it another problem: Typical anti­ox­id­ants that are used in elec­trical applic­a­tions have signi­fic­antly poorer heat storage prop­er­ties in temper­ature ranges above 120 °C, and continue to diminish further above 150 °C. High temper­ature anti­ox­id­ants contain metals and halides which can trigger electro corro­sion at junc­tions of elec­trical compon­ents thus short­ening their useful life. The chal­lenge faced by Bruegge­mann’s product devel­op­ment and applic­a­tions labor­atory team was to develop a stabil­izer that provides the neces­sary temper­ature protec­tion without any further draw­backs like electro corro­sion. The new metal and halide free BRUG­GOLEN® TP-H2062 does just that with the added bene­fits of being espe­cially dust free and having superior polymer dispers­ib­ility.

Through its state-of-the-art responses to the needs of the market­place, Bruegge­mann continues to be an invalu­able partner to its customer base and makes some of the innov­a­tions being intro­duced by E-mobility possible.
