Insulating material with a beautiful name in the French manner - Duroston, is fiberglass. It is made by mixing fiberglass with vinyl ester, polyester, epoxy resins. We can say that this is reinforced plastic, which received fiberglass armor. In terms of strength, this polymer is superior to other layered electrical insulating materials, as well as in terms of thermal and chemical characteristics. If we compare with foreign analogues of the same raw material class, then duroston is comparable to glass fiber laminates of such brands as STEB, STEF-1, STEF, STEF-U.

The material is characterized by thermal and chemical resistance, excellent dielectric properties. Therefore, duroston has found application in the industrial sector as a structural and electrical insulating material. Often duroston is used:

     in arc chutes;

     as an insulating material for busbar holders;

     for the arrangement of switchboards;

     for isolation of the block of low-, high-voltage switches.

As for the color performance, the material can be gray, red or white.

Since duroston has high structural strength, chemical and thermal resistance, its use involves extreme environmental conditions. The insulator retains its original strength even under the condition of prolonged exposure to temperatures ranging from 200 to 280 °C. The maximum passport value (maximum operating temperature) is 385 °C. But, even at such high temperature values, the composite does not deform, remaining flat and smooth for 10-20 seconds. From this it follows that duroston is excellent for production lines that generate a large amount of thermal energy (according to RoHS standards).

Mechanical characteristics and advantages of duroston

Thanks to its dimensional stability and increased rigidity, duroston can be processed mechanically. This fact makes it possible to use the polymer in the manufacture of structural components of non-standard shapes and sizes. Duroston has been measured to have a tensile strength of 20,000psi in static bending. At high heat, this value drops to 15000psi.

From the above, we can draw the following conclusions about the benefits:

     excellent chemical inertness;

     dimensional stability under any operating scenarios;

     highest mechanical strength;

     close to record antistatic performance, turning duroston into the best insulator.

     high accuracy in dimensions, layer thickness and other physical parameters.

Of all the insulating materials, duroston is the most technologically advanced and versatile composite.

Characteristics of products made of polyester fiberglass

Duroston products are available as thin base plates or soft mounting plates. Composite can also be found in the form of baseplates supporting non-standard cases. To improve performance, several panels are linked together. An insulator is often used when soldering at high temperatures to protect the backing plates. Duroston is considered an ideal base for applying Teflon coating. With it, the edges of the board are protected from contamination that may remain from the touch of human hands.

If the job involves wave soldering, protecting SMT components with Duroston is indispensable. During welding, duroston protects the base plates from deformation. On rare occasions, insulator plates serve to standardize the width of a production line, or to protect the outer layer of any surface from tin or contaminants.

If we try to reduce the information about the areas of application of duroston to the size of a short list, we get the following list.

     Wave solder, SMT, "classic" soldering

     Screen printing

     surface mountas much (SMT)

     On-site testing (creation of frame structures)

     Solder crystallization (composite melting by means of infrared radiation)

Despite the fact that duroston is not explosive and non-toxic, safety precautions must be observed when working with it. In particular, during the mechanical processing of the composite, dust harmful to humans, consisting of a fine suspension of fiberglass and polyester resin, rises into the air. Therefore, when cutting material, use a respirator and goggles.

Physical and mechanical properties of duroston

We have already talked about the strengths of this composite, and now we can proceed to a more detailed review of the “subject” in numbers. Note that all the values below were obtained within the framework of tests standardized by the international systems ISO, IEC and METTLER TMA.

     Density - 1.82 g / cm3

     Compressive strength – 250 N/mm2

     Elasticity – 9000 N/mm2

     Bending strength - 129 N/mm2

     Water absorption - 0.2%

     Tensile strength - 70 N/mm2

     Current and leakage resistance - CTI 600

Separately, we single out a high level of resistance for current breakdown. The insulator withstands 72 kV/mm at 90°C, which is sufficient for any extreme operating scenarios.

Duroston is made by the method of hot pressing. The plates are produced in five popular sizes: from 2 to 50 mm thick (2x1.25 m), from 0.8 to 3 mm (2.02x1.02 m), from 1.6 to 50 mm (2.47x1.25 m ), from 55 to 100 mm (1.95x1.2 m).

Most often, duroston is considered as a worthy replacement for asbestos-containing sheets, grade ACEID, due to lower water absorption, as well as arc and electrical resistance. On the world market, duroston is commercially labeled GPO3+, GPO3. The GPO3+ grade has improved bending strength, elasticity, impact strength and tear strength compared to GPO3. But at the same time, it is inferior to the brand without a “plus” in terms of breakdown voltage resistance.

DUROSTONE UPM 203

Layered fiberglass imported (Germany). Duroston UPM 203 is produced by hot pressing glass mat and binder, based on modified unsaturated polyester resin and fillers. The material has a homogeneous structure, has dielectric and structural properties. Duroston UPM 203 is arc resistant.
