Fiberglass rod 20 mm x 1 m - is essentially a rod in the form of a "roll" of fiberglass, impregnated to give it additional properties with binder chemicals - phenol-formaldehyde and epoxy resins. Structural fiberglass is characterized by good mechanical and dielectric properties, in addition, it can be used at high operating temperatures. Also, it does not interact with various substances (that is, it is a chemically stable material), it is explosion-proof, and during the operation of products from it there is no release of any harmful substances into the air.
The working temperature for fiberglass products is a temperature of up to 40 degrees Celsius, but short-term heating up to 155 degrees is also considered acceptable - while the material is not harmed, its properties do not change.
GOST 12652-74 describes the properties of fiberglass and requirements for it. All manufactured structural fiberglass is divided into markings (STEF, STEF-1, STEF-U). These varieties differ in that some significant individual characteristics vary in them - for example, the density of fiberglass, its mechanical strength and electrical stability. The most dense is STEF-U fiberglass.
Fiberglass in rods is used as a structural material at various manufacturing enterprises - in the fields of radio electronics, instrumentation, automotive and mechanical engineering, in the energy industry, etc. From the rods, such details of mechanisms are obtained, such as gears, bushings, "crackers" for the nodes of mechanisms, and so on. The rods can be subjected to all types of machining: turning, cutting, etc.
Steklotekstolit rod or steklotekstolit circle consists of several layers of glass fiber impregnated with a phenol-formaldehyde binder. Fiberglass rods have high electrical insulating and mechanical characteristics. Operation at very high temperatures is allowed. These characteristics of fiberglass rods provide a wide range of applications as a structural, electrical and thermal insulation material in industry, radio electronics, mechanical engineering and energy.
Fiberglass rods are used as a structural material in mechanical engineering, radio electronics, instrumentation, energy and other areas. They are used in the manufacture of bushings, gears, in the nodes of machines and devices.

Making a fiberglass rod
The fiberglass rod is made from fiberglass using hot pressing, which is impregnated with epoxy or phenol-formaldehyde resins for bonding. Rack material at elevated temperatures, strong mechanical loads and high voltage.
Fiberglass rod properties
Fiberglass products have the following physical and technical characteristics:
work in the relative humidity of the environment 45-75% at -15 to +35°С;
operation at high humidity of 93% at a temperature of +40°С;
operating voltage over 1000 V;
current frequency up to 50 Hz.
Fiberglass rods do not lose their original properties within 20 years of use.
Application of fiberglass rod
The fiberglass rod is used as a structural material in various industries, such as: radio electronics, mechanical engineering, energy, instrumentation, aviation and shipbuilding. It is used to produce: bushings, gears, containers for storing chemical liquids, the outer walls of devices.
In the domestic sphere, fiberglass rods are used to make: smoke exhaust pipes, fishing rods, windows, panels for cars, boats, etc. Modern manufacturers produce many grades of this plastic, which differ from each other in physical and technical properties.
