EPGC308 epoxy glass fiber cloth laminated sheet thermal resistant for motor slot wedge insulation
EPGC308 is a product made by impregnating epoxy resin matrix onto electronic-grade alkali-free glass fiber cloth and processed through heat pressing. This product meets the requirements of IEC60893-2004 and GB/T 1303.4-2009 standards. It has a brownish yellow color.
1.Remarkable mechanical strength at medium or elevated temperatures, including a tensile elongation of more than 50% even at higher temperatures. This ensures its resilience and ability to withstand mechanical stress effectively.
2.Consistent electrical performance, characterized by an insulation resistance of up to 1012Ω even after being immersed in water. This demonstrates its reliable and stable electrical insulation capabilities.
3.Enhanced dielectric strength under high humidity conditions (exceeding 35kV) when laminated parallel to the layers. This feature makes it particularly suitable for applications requiring dependable electrical insulation in humid environments.
