La MisoletVetroniteVetronite

Vetronite is a composite material with excellent dielectric and mechanical properties, which can differ according to the kind of resin and fiberglass employed. It is applied in almost every industry: aeronautics, shipbuilding, energy and robotics.

The best-known resins are epoxy (G10, FR4, G11, FR5), melamine (G5), silicone (G7), polyester (GPO3); they are available in sheets, tubes and rounds.

MaterialsG10/FR4 – G11/FR5
Epoxy glass

Epoxy glasses have a glass fabric as support, with specific features aimed at retaining the epoxy resin that impregnates the glass fabric, which is then heat-pressed at high temperature to obtain laminates with excellent mechanical properties, electric insulation even in wet environment, chemical resistance, tensile strength, compression and dimensional stability.

Epoxy glasses are mainly used in the electromechanical and electronic industry. Low-thickness epoxy glasses are employed for headers, washers, contact carriers; large-thickness epoxy glasses are used to manufacture various shapes that need dielectric insulation and mechanical strength, according
to customers’ drawings. They are ideal for the molding industry as press plates’ insulator and in the manufacture of screws, nuts and bolts.

G10, FR4, G11 and FR5 materials have similar mechanical and insulation properties. Only FR4 and FR5 are UL 94-V0 self-extinguishing. FR5 vetronite is also halogen-free.

G5 melamine glass and G7 silicon glass

G5 consists of several layers of fiberglass fabric impregnated with melamine resin by means of a thermal process and under pressure; it is a flame-retardant and arc-resistant material. On the contrary, G7 is impregnated with silicone resin, which makes it even more heat-resistant, being a class H insulation material (180°); in all other respects, these two materials have similar mechanical and insulation properties.

They can be employed as insulation parts in grooves of high-temperature motors, as arc fault detection devices in switches and similar applications.

These glasses are mechanically inferior to epoxy glass, but they have a high resistance to sparks that occur when a switch turns the power on or off (arc resistance).

They are both UL 94-V0 self-extinguishing materials.

Polyester glass
GPO3

Made of glass MAT impregnated with polyester resin, polyester glass is mainly employed in the electromechanical industry. The continuous filament improves its mechanical tensile strength and allows cold punching for thicknesses up to 5mm.

GPO is used to produce vanes, air gaps, washers, grip bars, protection panels, rings, gaskets for high, medium and low-voltage disconnectors, electrical cabinets, transformers, power transmission and rail transport.

It is a UL 94-V0 self-extinguishing, halogen-free, low-smoke and low-toxicity material; it has low water absorption, excellent comparative tracking index and arc resistance.
