Vetronite (or Epoxy Glass or Fiberglass) is a glass fiber composite material placed orthogonally between two layers in an epoxy resin matrix, widely used as an insulator, found in many electronic devices including household appliances and power tools. Very durable and, above all, very insulating material finds its greatest use in the manufacture of printed circuits on which the electronic components will be assembled to make the circuits.
- It is lightweight but has a high mechanical strength
- Good dielectric properties and low water absorption.
- Good resistance to sudden short-term thermal swings but not long-term, as the resins contained tend to become carbonated.
- It is a flame resistant product and is self-extinguishing.
The maximum working temperature of the windscreen is lower than that of many other electronic components.
The FR4 Vetronite is used in the mechanical and electrical industry or as a base for electronic boards.
It is used in the molding of plastics as an insulator between die and press plane, for transformers, supports and panels in the electromechanical field.
