Inta badan waxaa loo isticmaalaa walxo ceeriin ah oo loogu talagalay polyimide, iyo wakiilka isku xidhka si loo soo saaro wakiilka daaweynta epoxy iyo baabi'inta resin polyester.
Pyromellitic acid (PMA), oo sidoo kale loo yaqaan 1,2,4,5-benzenetetracarboxylicacid, oo ah budo cad ilaa huruud ah, ayaa inta badan loo isticmaalaa isku-darka polyimide, octyl pyromelliate, iwm., waa walaxda ugu weyn ee loo isticmaalo soo saarista wakiilka daaweynta matting.
