Application characteristics of flame-retardant insulation board for processing heterogeneous mica parts

1. Convenient curing

Using various curing agents, the epoxy resin system can almost be cured in the temperature range of 0 ~ 180 ℃.

2. Various forms

Various resins, curing agents, and modifier systems can almost adapt to the requirements of various applications, ranging from extremely low viscosity to high melting point solids.

3. Low shrinkage

The reaction between the epoxy resin and the curing agent used is carried out by direct addition reaction or ring-opening polymerization reaction of epoxy groups in the resin molecule, and no water or other volatile by-products are released. Compared with unsaturated polyester resins, they show very low shrinkage (less than 2%) during curing.

4. Strong adhesion

The inherent polar hydroxyl groups and ether bonds in the molecular chain of epoxy resins make it highly adhesive to various substances. The shrinkage of epoxy resin is low when curing, and the internal stress generated is small, which also helps to improve the adhesion strength.

5. Mechanical properties

The cured epoxy resin system has excellent mechanical properties.

6. Stable electrical insulation

Good flatness, smooth surface, no pits, thickness tolerance exceeding the standard, suitable for products requiring high-performance electronic insulation, such as FPC reinforcement board, high temperature resistant board for tin furnace, carbon diaphragm, precision cruise star, PCB Test frame, electrical equipment insulation partition, insulation backing plate, transformer insulation, motor insulation, deflection coil terminal board, electronic switch insulation board, etc.
