Description

• Product Size: 100x100mm 200x200mm 200x300mm 300x300mm Regular thickness: 0.5mm--10mm Colour:Black please touch me if you want different colours,thickness or other dimensions   3240 Epoxy Board meaning: 3240 is the nationwide regular number, resembling the EPGC201 sort in IEC893-3-2. According to JB-T 2197-1996 electric insulation material product classification, naming and mannequin preparation method:   3240 four Arabic numerals:   The first three represents laminates, coiled products, vacuum pressure dipped products The second place 2 represents the inorganic base laminate The third 4 represents the temperature index point F (155 degrees) The fourth digit zero represents the product range code   The 3240 epoxy laminate has a tender surface, no air bubbles, no pits and wrinkles, but permits for different defects that don't affect the use, such as: scratches, indentations, stains and small spots. The edges should be lower smartly and the tip faces must be free of delamination and cracks.   Executive standard: GB/T1303.1-1998. Temperature rating: Class B Color: pure (yellow), green, etc.   Characteristics: The cured epoxy resin method has splendid mechanical properties, excessive energy at medium temperature, and good electric balance under high humidity.   Electrical: The cured epoxy resin formula is a good insulating materials with high dielectric properties, floor leakage resistance and arc resistance.   Uses: Suitable for mechanical, electrical, electronic, electrical and different fields. Also used for the processing of insulating parts, processing into various sorts of insulating parts and equipment insulation structural parts.   The response of the epoxy resin and the curing agent used is applied through a direct addition reaction or a ring-opening polymerization response of an epoxy group in a resin molecule, with out the release of water or different unstable by-products. They reveal very low shrinkage (less than 2%) during curing compared to unsaturated polyester resins and phenolic resins.
