GPO-5 UPGM205 Unsaturated Polyester Glass Mat Sheet HM2472 Insulation Board

product details

Description

GPO-5 / UPGM 205 is a fiber-reinforced thermosetting material with higher temperature resistance. It canbe used at high temperatures of 155°C for a long time without deformation or blistering. It usesfiberglass mat or fiberglass cloth as a reinforced skeleton and has excellent mechanicalproperties and a specific UL flame retardant rating.

Compared with GPO-3 in tensile strength, complete strength of the corresponding upgrade products. It has the same electrical, thermal and combustion properties as GPO-3 sheet. Higher mechanical properties than GPO-3 sheets (better tensile and bending strength at high temperatures).


Features

  • Made from alkali-free glass fiber mat impregnated with vinyl resin and chemical additives

  • Excellent electrical performance under high humidity conditions

  • Good mechanical properties at medium temperatures

  • Flame retardant with good arc resistance and tracking resistance

  • High dimensional stability and durability

  • Suitable for electrical insulation in low-voltage equipment


Applications

  • Low-voltage electrical equipment

  • Phase and terminal grids

  • Insulating brackets and busbar supports

  • Mounting panels for switchgear

  • Components requiring reliable electrical insulation under humidity

  • Mechanical parts with moderate temperature and flame-retardant requirements
