3240 epoxy plate / stick meaning:
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 stands for temperature index class 155 degrees
Fourth bit 0 represents product variety code
3240 for epoxy glass laminate
3240 epoxy plate / rod properties:
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.
Temperature tolerance grade:B
Characteristic：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 an excellent insulating material with high dielectric properties, resistance to surface leakage and arc resistance
Uses:It is suitable for mechanical, electrical, electronic, electrical and other fields. Also used in the processing of insulation parts, processing into all kinds of insulation parts and equipment insulation structure parts.
Thickness:Under normal circumstances, 0.3 ~ 50mm, also can be produced according to the requirements of 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. Compared with unsaturated polyester resin and phenolic resin, they show very low shrinkage (less than 2%) during curing.

Application characteristics of FR4 water green epoxy board / stick:
1, diverse forms. Various resins, curing agents and modifier systems can almost meet the requirements of various applications for the form, ranging from very low viscosity to high melting point solids.
2, easy curing. The epoxy resin system can be cured almost in the temperature range of 0~180 degrees with various curing agents.
3, strong adhesion. The existence of polar hydroxyl and ether bonds inherent in the molecular chain of epoxy resinIt has a high adhesion to various substances. When epoxy resin is cured, the shrinkage is low and the internal stress is small, which also helps to improve the adhesion strength.
4, low contractility. 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. Compared with unsaturated polyester resin and phenolic resin, they show very low shrinkage (less than 2%) during curing.
5. Mechanical properties. The cured epoxy resin system has excellent mechanical properties。
