GPO3 glass fiber polyester laminate board

GPO-3
GPO-3 is a fiberglass laminate consisting of polyester resin 
reinforced with fiberglass mat base for applications up to 
155°C with good thermal, mechanical and electrical
properties. An excellent material to work with, it displays 
good mechanical strength. Thinner dimensions are also 
ideal for punching. 
• Compliant with: NEMA – GPO3, DIN 7735 – HM 2471, 
 EN60893/IEC893 – UPGM 203
• Good thermal properties
• Very good electrical properties
• Good mechanical properties
• Classified flame resistant

GPO-3 is suitable for a broad range of applications within the electrical and mechanical sectors and is used extensively in 
the manufacture of spacers, mechanical barriers, electrical components/spacers, etc.

Properties
• Low moisture absorption
• Very high CTI value (Comparative Tracking Index)
• High heat resistance 155°C without major 
 impact on the good mechanical properties
• Classified flame resistant
• High chemical resistance
• Resistant against most impregnation varnishes 
• Very good dielectric properties 
• Highly suitable for punched parts 
Composition
• Fiberglass mat base with polyester resin 
compressed and cured under high pressure 
to comply with defined industry standards.
