* In powder coating some materials can be used just once, for example EPDM which has a top temperature resistance of 125°C but
can actually standard temperatures up to approx. 200°C. EPDM plugs get harder but do not melt.

** Thermoplastics like PA actually start melting at approx. 160°C but can be stabilized in some different ways, for example with a
mixture of glass fibres.
