Manufactures 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
The size, diameter,
or "count" of a Asbestos 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.
Several ends of Asbestos yarns can be twisted or braided to
produce the yarn or rope of a higher diameter. The asbestos
yarn can be reinforced with ductile metal wire 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.
Asbestos yarn has a
wide range of applications -in heat insulation, sealing,
electrical insulations, fire protection, friction materials
etc. The 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 cloth, which services
the wide ranging needs of any industry.
