Specific Weight of Textolite: Weight of 1 m³, Density and Reference Table

Textolite is a laminated structural and electrical insulating material. It is produced by impregnating fabric with a polymer binder and then pressing it. Phenolic, bakelite, polyester and other resins may be used as the binder.

The material is used to manufacture gears, bushings, sliding bearings, electrical components, radio equipment parts and other products where mechanical strength and electrical insulation properties are important.

Different grades of textolite use fabrics with different weave patterns and densities. The base fabric, binder type and pressing process affect strength, impact resistance, splitting resistance and the density of the finished material.

Textolite is produced as sheets, plates, rods and other blanks. Sheet thickness can vary significantly depending on the grade and application.

Textolite Specific Weight Table

The table below gives average reference values. Exact density depends on the textolite grade, fabric type, binder content and production technology.

For many common textolite grades, actual density is closer to 1300-1450 kg/m³, but a wider reference range of 1300-1600 kg/m³ is often used for preliminary calculations.

How to Calculate Specific Weight

Specific weight is the ratio of a material’s weight to its volume. It is calculated with the formula:

γ = ρ × g

where:

• γ is specific weight;
• ρ is material density;
• g is gravitational acceleration, approximately 9.81 m/s2.

The result is expressed in N/m³. If textolite density is taken as 1300-1600 kg/m³, its specific weight is approximately 12.8-15.7 kN/m³.

Textolite Density

Density shows how much mass of material is contained in one cubic meter. For textolite, this value depends on composition, fabric density, resin content, moisture and pressing level.

For engineering calculations, it is better to use data for the specific grade and manufacturer. If such data is not available, an approximate range of 1300-1600 kg/m³ can be used.

Conclusion

The weight of 1 m³ of textolite is usually taken as 1300-1600 kg. For more accurate calculations, the material grade, reinforcing fabric type and actual density from the technical data sheet should be considered.
