EPOXY FIBER BOARD ( FR4 )

FR4 Sheets are produced by impregnating alkali-free glass fiber fabric with epoxy resin binder and keeping it under high temperature and high pressure. These products show very good temperature and humidity resistance, as well as high mechanical strength, good di-electric properties, and good electrical strength properties.

Features:

Excellent resistance to flame.
Friction resistant.
Resistance to water.
Excellent sound insulation.
Dimensional stability over a wide temperature range.
Excellent resistance to mechanical loads.
