Sraith PTMG/TDI
cruas: cladach A 75A – cladach D 60D
Tá tréithe dea-inoibritheachta ag an táirge, raon cruas leathan, athléimneacht maith, friotaíocht caitheamh agus airíonna meicniúla den scoth.
Úsáidtear é chun táirgí ilghnéitheacha leaistiméire polúireatán a dhéanamh, mar shampla roth rubair ard-leaisteach, pláta scáileáin, sorcóir rubair, fáinne ina saothraítear rónta.
