3240 for epoxy glass laminate
Conventional thickness: 0.3mm--50mm
Whole Zhang Changkuan: 1 meters *2 meters（Cut zero(actual size: about 1020mm*2020mm)
Color: yellow, water, green
3240 epoxy plateMeaning：
3240 is the national standard, corresponding to the EPGC201 type in IEC893-3-2.
According to JB-T2197-1996 electrical insulation material classification, naming and model compilation method:
3240 Arabia four digits
The first 3 represents lamination, winding products, vacuum pressure impregnation products
Second bit 2 represents inorganic laminate
Third bit 4 represents temperature index class F class 155 degree
Fourth bit 0 represents product variety code
Properties of 3240 epoxy plate:
3240 epoxy laminate surface is smooth, no bubbles, no pits and wrinkles, but allow other defects that do not affect the use, such as: scratches, indentation, stains and a small amount of spots. The edge should be cut neatly, and the end face shall not be divided into layers and cracks.
Implementation criteria: GB/T1303.1-1998.
Temperature tolerance grade: F
Color: natural (yellow), green, etc.
Characteristics: after curing epoxy resin system has excellent mechanical properties, high temperature strength Jie machine, good electrical properties under high humidity.
Electrical property: the cured epoxy resin system is a kind of excellent insulating material with high dielectric property, surface leakage resistance and arc resistance
Usage: suitable for mechanical, electrical, electronic, electrical and other fields. It is also used for the processing of insulating parts,It is processed into all kinds of insulation parts and equipment insulation structure parts.
Thickness: under normal circumstances is 0.3 ~ 50mm, can also be required to produce 50~150mm thick plate.
The reaction between epoxy resin and curing agent is carried out by direct addition reaction or ring opening polymerization of oxygen in the resin molecule,No water or other volatile by-products are released. They are compared to unsaturated polyester resins and phenolic resins,Low shrinkage (less than 2%) was observed during the curing process.
