BARC deals in asbestos yarns in a wide range of constructions with a wide range of properties dependent on the various applications intended. However, they are commercially distinguished under
the following groups:

A)  Non-metallic
B) Metallic-incorporating metal wire
C) Union-in combination with cotton threads. The size, diameter, or “count” of a yarn can be expressed in many ways-The modern international method used is the TEX system. The “TEX NUMBER” indicates the weight of yarn in grams per Km. length.

Several strands of yarn can be twisted or braided to produce the yarn or rope of a higher diameter.
The yarn can be reinforced with ductile metal wires such as brass, copper, zinc, lead, inconel, monel, stainless steel, etc.

Reinforcement with filaments of metal wire offers particular properties in the end product, such as heat dissipation, high temperature resistance, strength retention or particular friction properties. It can also be spun in combination with cotton or yarns made with man-made fibres to give an added advantage of higher strength and flexibility in lower temperature applications.

Asbestos yarn can also be treated with high quality lubricants, oil resisting compounds, PTFE and coated with flake graphite or mica for specific applications.

SERVICE :  Asbestos yarn has a wide range of applications—in heat insulation, sealing, electrical insulations, fire protection, friction materials, etc. Asbestos yarn is also used for packing valve spindles, lagging small pipes, sealing joints in flexible metallic tubings, packing for bib-cocks at low pressure steam, sewing asbestos mattresses, in switch and fuse gear, braiding of electric cables, weaving of electrical resistance kits, cushions for glass in patent glazing bars. In addition to this, the asbestos yarn forms a base for the manufacture of packings, tubings and cloths which service the wide ranging needs of any industry.
