7 high-quality properties of epoxy glass fiber board

The application field of epoxy glass fiber board is very wide. What are its high-quality properties?

1. Various forms. Various resins, curing agents, and modifier systems can almost adapt to the requirements of various applications.

2. Convenient curing. The epoxy resin system can be cured in the temperature range of 0-180℃ with various curing agents.

3. Strong adhesion. The inherent polar hydroxyl group and ether bond in the molecular chain of epoxy resin make it have high adhesion to various substances.

4. Low shrinkage. The reaction between the epoxy resin and the curing agent used is carried out by direct addition reaction or the ring-opening polymerization reaction of epoxy groups in the resin molecule, and no water or other volatile by-products are released.

5. Mekaniske egenskaber. Det hærdede epoxyharpikssystem har fremragende mekaniske egenskaber.

6. Elektrisk ydelse. Det hærdede epoxyharpikssystem er et fremragende isoleringsmateriale med høje dielektriske egenskaber, overfladelækagebestandighed og lysbue -modstand.

7. Kemisk stabilitet. Generelt har det hærdede epoxyharpikssystem fremragende alkalimodstand, syrebestandighed og opløsningsmiddelresistens. Ligesom andre egenskaber ved det hærdede epoxysystem afhænger den kemiske stabilitet også af det valgte harpiks og hærdningsmiddel. Passende valg af epoxyharpiks og hærdningsmiddel kan få det til at have en særlig kemisk stabilitet.
