Coffee Color Phenolic Cotton Cloth Fabric Sheet

Coffee Color Phenolic Cotton Cloth Fabric Sheet is a kind of insulation sheet, made of coarse cotton cloth impregnated phenolic resin by processing under heat and pressure. Phenolic Cotton Cloth Fabric Sheet is widely used for low voltage applications ,for machines & appliances having higher voltages but lower electrical stress (slot wedges ,spacers) as material for bearing , gears , rollers & other constructional components , drilling jigs , underwater bearings , telecommunication & high frequency technique property ,oil resistance and dielectric property, as electrical materials with low electric property  1.Products show 2.Technical of laminated sheet  Properties Unit Grade     3025 Flexural strength perpendicularto laminations ≥ MPa 100 Compression strength perpendicular To laminations ≥ MPa 245 Bonding strength ≥ N 5400 Dielectric StrengthPerpendicular to Laminations(in 90±2°C transformer oil,1mm in thickness) ≥ KVmm 0.82 Breakdown voltage parallelto laminations(in 90±2°CTransformer oil) ≥ kV 1 Permittivity(1MHz) ≤ - 5.5 Dissipation factor(1MHz) ≤ - 0.04 Insulation Resistance afterimpregnated in water ≥ Ω 1.0×106 Density   gcm3 1.45-1.5 Water absorption(1mm in thickness)   mg 206 Color   - Brown Tensile strength ≥ MPa 98 Impact strength ≥ KJm2 8.8 Temperature index(short time). ≥ - 120   3. Applications of laminated sheet
