Grade 1130 - Industrial Composite Angles and Channels

Electrical Insulating Structural Products

Grade 1130 is a fiberglass-reinforced thermoset polyester composite system which exhibits a unique combination of properties which make it attractive for a variety of applications. Grade 1130 possesses:

  • Flame Resistance
  • Corrosion Resistance
  • Weatherability
  • Dielectric Properties

This system is formulated from a special methyl methacrylate modified neopentyl glycol-isophthalic acid unsaturated polyester resin. This type of resin has long been known for outstanding resistance to color fading caused by sunlight and for resistance to surface erosion caused by weathering. This family of resins is also recognized for its performance in corrosive environments, including acids, bases and aliphatic hydrocarbons.

The mineral filler used in the 1130 system has been selected to provide a flame resistance rating of V-O when tested according to the UL® Section 94. It also meets the National Electrical Manufacturers Association (NEMA) criteria for grade GPO-3.
