3240 epoxy board meaning:
3240 is the national standard number, corresponding to the EPGC201 type in IEC893-3-2.
According to JB-T 2197-1996 electrical insulation material product classification, naming and model preparation method:
3240 four Arabic numerals:
The first 3 represents laminates, coiled products, vacuum pressure dipped products
The second place 2 represents the inorganic base laminate
The third 4 represents the temperature index level F (155 degrees)
The fourth digit 0 represents the product variety code
The 3240 epoxy laminate has a smooth surface, no air bubbles, no pits and wrinkles, but allows for other defects that do not affect the use, such as: scratches, indentations, stains and small spots. The edges should be cut neatly and the end faces must be free of delamination and cracks.
Executive standard: GB/T1303.1-1998.
Temperature rating: Class B
Color: natural (yellow), green, etc.
Characteristics: The cured epoxy resin system has excellent mechanical properties, high strength at medium temperature, and good electrical stability under high humidity.
Electrical: The cured epoxy resin system is an excellent insulating material with high dielectric properties, surface leakage resistance and arc resistance.
Uses: Suitable for mechanical, electrical, electronic, electrical and other fields. Also used for the processing of insulating parts, processing into various types of insulating parts and equipment insulation structural parts.
The reaction of the epoxy resin and the curing agent used is carried out by a direct addition reaction or a ring-opening polymerization reaction of an epoxy group in a resin molecule, without the release of water or other volatile by-products. They exhibit very low shrinkage (less than 2%) during curing compared to unsaturated polyester resins and phenolic resins.
