Description

• 3240 epoxy board meaning: 3240 is the national normal number, corresponding to the EPGC201 sort in IEC893-3-2. According to JB-T 2197-1996 electrical insulation material product classification, naming and mannequin preparation method: 3240 4 Arabic numerals: The first three represents laminates, coiled products, vacuum pressure dipped products The second position 2 represents the inorganic base laminate The 0.33 4 represents the temperature index level F (155 degrees) The fourth digit zero represents the product diversity code   The 3240 epoxy laminate has a smooth surface, no air bubbles, no pits and wrinkles, yet allows for other defects that don't affect the use, such as: scratches, indentations, stains and small spots. The edges must be cut smartly and the top faces should 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 formula has ultimate mechanical properties, high power at medium temperature, and nice electrical balance below high humidity. Electrical: The cured epoxy resin formula is insulating materials with excessive dielectric properties, floor 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 assorted styles of insulating elements and equipment insulation structural parts.   The reaction of the epoxy resin and the curing agent used is carried out by means of a direct addition response or a ring-opening polymerization reaction of an epoxy organization in a resin molecule, with out the discharge of water or other risky by-products. They show very low shrinkage (less than 2%) throughout curing compared to unsaturated polyester resins and phenolic resins.
