OT (ornamental textolite). The simplest kind of textolite on a woven cotton basis, serves for production of the details working at low mechanical loadings. The most widespread and inexpensive brand. Rod ornamental textolite – popular material for production of decorative handles of knives.
OTC (ornamental textolite constructional). This textolite is made also on the basis of cotton fabric, but differs from usual PT in the best physicomechanical properties and a good workability. It allows to make of it worm gear wheels, plugs, bearings of sliding, a ring, rollers and other constructional products. In comparison with analogs from metal, products from PTK easier, by 10 times serve longer and silently work. PTK is exposed to grinding, milling, sawing and drilling without formation of stratifications, cracks or chips. Range of working temperatures of PTK – from-40 o C to +105 o C.
PTM (ornamental textolite resistant to transformer oil). In the sphere of mechanical engineering the materials steady against high temperatures and influence of the warmed lubricant oils often are required. Such material is PTM textolite on a woven basis of which it is possible to make products of technical appointment (the plug, gear wheels, cams, bearings). It maintains temperature to +120 o C. Density of PTM makes 1,3 - 1,4 / cubic cm that allows to maintain high loads of a bend and compression.
PTG. At the heart of this textolite – thermoreactive binding and graphite. From PTG make the condensing washers for water pumps.
Asbotekstolit. Textolite on the basis of asbestine fabrics from the hydrosilicate mineral fibers bound with viscose or cotton. Due to good frictional properties it is used at production of details of brake mechanisms, mechanisms of coupling and laying for work at the increased temperatures. In aerospace equipment it is applied to providing an external and internal heat-shielding. Asbotekstolit can it is long to maintain influence of temperatures to +200ºС, short time – to 250–500ºС. With a temperature up to 1 800-45 000ºC this material is also capable to transfer short-term flashes.
Brands A and B (textolite electrotechnical). Irreplaceable material for production of the details subject to sign-variable electric and mechanical loadings. Being the electroisolating material this textolite finds the application for work in transformer oil, and also on air with a frequency of current of 50 Hz. At operation conditions of normal humidity are required, and working temperatures make from-65 o C to +105 o C. Textolite of brand A is more often applied as insulating material, and also to production of printed circuit boards. Brand B textolite in addition has the improved mechanical characteristics and finds application as constructional material. Both brands are made on a woven basis.
VCh textolite. This brand of textolite is used for production of details of electrotechnical appointment, for work in transformer oil and on air in the conditions of normal relative humidity of 45-75% at a temperature of 15-35 °C and frequency of current of 106 Hz
LT textolite. Such brand of textolite is, as a rule, used for production of details of electrotechnical appointment, for work in transformer oil and on air in the conditions of normal relative humidity of 93% at a temperature of 40 °C and frequency of current of 50 Hz.
Rod textolite. Cores electrotechnical textolite round represent the layered pressed material made by method of winding and consisting of several layers of the cotton fabric impregnated with thermoreactive binding. It is used in construction, mechanical engineering and electrical equipment. Textolite keeps the mechanical and physical properties in the environment of weak acids, products of oil synthesis and water.
Manufacture bearings, elements of friction, the plug and inserts of it. Rod textolite is made of fibers of cotton fabric with impregnation from binding substances. Material is easily processed and on some mechanical properties does not concede even to metals. Length of cores: from 500 to 1000 mm. Diameters of cores: 8, 13; 18; 25,0; 40; 50; 60; 80; 100; 120; 145; 175; 200 mm.
All brands of textolite are delivered across Ukraine from a warehouse to Dnipropetrovsk in the form of sheets 0,5-100 mm thick, and also cores with a diameter of 8-200 mm.
