1, the product adopts high quality, wax-free, E-glass and electric fiber yarn as the substrate, knitted into a variety of mesh cloth, and is made through heat drying dehydration, and then impregnated with epoxy resin mixture unique formula, dispensing glue under moderate temperature, and heat drying curing. 2, according to the property of the impregnated resin, the products can be divided into solvent and solvent-free mesh mesh. The main differences between the two mesh are as follows: 2.1, impregnated resin is different: Solvent Mesh contains acetone, solvent-free mesh is pure resin. 2.2, different procedures of impregnation: Solvent mesh is impregnated at normal temperature air, and it is opaque; while solvent-free mesh is impregnated under the medium-temperature vacuum pressure, and the mesh is transparent. 2.3, containing different amounts of plastic: The proportion of resin contained in solvent-free mesh is much larger than a solvent mesh, about twice of the solvent mesh. 2.4 application is different: Solvent-free mesh is suitable as an insulating layer between the coils with no partial discharge at very high field intensity the use of solvent-free mesh can reduce the thickness of the interlayer insulation.
