Phenolic Resin
Phenolic resin is a highly crosslinked thermosetting material that is produced by poly-condensation of phenol and formaldehyde. As one of polymer materials, phenolic resin features good heat resistance, flame retardancy and electric insulation and takes an important part in many industries.
Micronized Silica
When acid is added to sodium silicate, silica sol with primary particle is created. Raclical dehydration condensation reaction is promoted at silano(Si-OH) on the surface of primany particle by continuous adding of acid. As a result, network (Si-O-Si) is formed and three dimensional structure is generated. This is so called Silica gel. Physical properties are controlled via washing and drying processes and finally Micronized silica is produced by grinding it. Micronized silica has various special propertie by porosity and paricle size distribution, and it is applied widely in various fields using the characteristics.
