Product Description Product DescriptionEpoxy insulation board: It is made of glass fiber cloth and epoxy resin bonded by heating and pressing.WIth high mechanical properties at medium temperature and stable electrical properties at high temperature.Has high mechanical and dielectric properties, as well as good heat and moisture resistance. Heat resistance class F (155 oC).Suitable for high-insulation structural parts for machinery, electrical appliances and electronics.Thickness: 0.5~100mmRegular size: 1000mm*2000mmProduct Features1. Various forms. A wide variety of resins, curing agents, and modifier systems are available to suit virtually every application's form requirements, ranging from very low viscosities to high melting point solids.2. Easy to cure. Epoxy resin system can be cured in the temperature range of 0~180oC.3. Strong adhesion. Epoxy resins have low shrinkage when cured and generate little internal stress, which also contributes to improved adhesion strength.4. Low shrinkage. The curing agent reacts without the evolution of water or other volatile by-products. Very low shrinkage (less than 2%) during curing.5. Mechanical properties. The cured epoxy resin system has excellent mechanical properties.Product ParametersNo.ItemUnitStandard Value1Densityg/cm31.7-1.9 2Bending StrengthMDMpa≥392TD≥2943Tensile StrengthMDMpa≥343 TD≥2454Martens temperature (MD)oC≥2005Adhesive StrengthN≥56846Impact strengthMDKJ/m2≥150TD≥1007Surface ResistivityIn normal conditionMΩ ? m≥1.0 x 105after immersion in water≥1.0 x 1038Parallel layer insulation resistanceIn normal conditionMΩ≥1.0 x 104after immersion in water≥1.0 x 1029Dielectric Loss Angle Tangent (50Hz) ≤0.05010Vertical layer to electrical strength(1mm) (90 ±2 oC in oil)MV/m≥1811Parallel layers breakdown voltage (90± 2 oC in oil)KV≥30
