Polyester glass mat laminates. 

TUFNOL Polyester glass mat laminates are produced by combining polyester resin with continu-ous roving glass mat. They are a useful group of materials that fall in price and performance between paper and cotton fabric laminates and high performance woven glass types. 

Two grades are available, offering compliance with NEMA Types GPO-2, NEMA GPO-3 and DIN 7735 Type Hm 2471.  These materials have excellent mechanical and electrical properties and are widely used in applications where good electrical insulation is required up to thermal class F temperatures (155°C). 

TUFNOL PGM Grades. 

 Grade PGM/2 An electrical grade with assessed flammabiltiy characteristics (UL 94 V-0). Good for cold punch-ing. Colour ivory. NEMA Type GPO-2. Suitable for thermal class F applications. Available in sheets from 0.8mm to 25mm thick. 

 Grade PGM/3 An electrical grade with assessed flammability characteristics (UL 94 V0) plus excellent arc and track resistance.  Colour red.  NEMA Type GPO-3 and DIN 7735 Type 2471. Suitable for thermal class F applications.  Available in sheets from 0.8mm to 25mm thick.
