Asbestos Teflon Packing Sealing in Pakistan


A material used to prevent the leakage of fluids or gasses between two surfaces. Seals are designed to create a barrier between two parts of a machine or system to prevent the escape of fluids or gases, or to prevent the entry of contaminants into the system.

They can take many forms, including O-rings, gaskets, packings, lip seals, and mechanical seals, and they are used in a wide variety of applications, from automobiles and appliances to heavy machinery and industrial equipment. The type of seal used depends on the application and the operating conditions, such as temperature, pressure, and the type of fluid or gas being sealed.

Asbestos Products

Asbestos is a group of naturally occurring minerals that are resistant to heat and corrosion.  It’s highly resistant to oils, fuels, solvents, and harsh chemicals, making it ideal for use in applications that require resistance to air and water.


The fireproofing capabilities of asbestos made it an ideal material to use in protective clothing such as jackets for firefighters and aprons and mitts for foundry workers.

Workers in foundries, glassworks and steel plants often wore asbestos garments to protect them from extreme temperatures and from burns while working with molten materials. Protective garments often consisted of coats, gloves, leggings and aprons. Employees who worked with furnaces and stood along the paths where molten metal flowed wore asbestos coats and leggings during the casting process.

Thermal insulation: Available for boilers, pipelines and other equipment of metallurgy, chemical factories, power plants, buildings, ships, vehicles, and so on.

  • Thickness: 1.2 mm to 3 mm
  • Width: 1 m
  • Packing: 50 KG

Asbestos rope is made of braided asbestos fiber and its section tends to be round, rectangle or square. It is widely used in centrifugal pumps, compressors, vacuum pumps, mixers and ship propeller shaft seals, piston pumps and so on. It has a good thermal conductivity, acid and alkali resistance. Compared with other sealing materials, asbestos rope can be molded into any shape and operates well at extreme temperatures. Especially, it has ability of halting the spread of fire.

Pure asbestos rope is designed for static sealing and operates well at high pressure and temperature working environments.

Asbestos rope is not often made of 100% asbestos. There are three kinds of sealing rope, which are treated with other materials to improve their comprehensive properties. It is also called asbestos packing.

Following are the ideal applications for Asbestos Rope:

Boiler insulation: asbestos rope is commonly used to insulate boilers and other high-temperature equipment.

Pipe insulation: asbestos rope is used to insulate pipes and other equipment that carry hot fluids or gasses.

Sealant: it is used as a sealant in engine and boiler applications to prevent leaks.

Fireproofing: it is used as a fireproofing material in buildings and structures.

Packing material: asbestos rope is used as a packing material in pumps and valves to prevent leaks.

Electrical insulation: in certain applications.

Seals and gaskets: in gas or electric heating appliances.

  • Thickness: 3 mm to 50 mm
  • Packing: 2.5 KG – 25 KG (varies with thickness)

Asbestos tape or insulating tape is made of high quality woven chrysotile/white asbestos. It has ability to withstand harsh working environments.

As asbestos has good resistances to fire, heat, chemical and electrical damage, asbestos tape is often applied as conveying tape and is widely used in industry, metallurgy where needs heat-resistant materials.

  • Thickness: 3 mm & 6 mm
  • Width: 25 mm to 100 mm
  • Packing: 2.5 KG & 5 KG (varies with thickness)

Non Asbestos / Fiber Glass Products

Fiberglass is a material consisting of numerous extremely fine fibers of glass. Fiberglass is an essential component for wide range of industries including water treatment plants, HVAC, fireproofing, and oil fields.

Properties of Fiberglass Products

  • Mechanical strength: Fiberglass has a specific resistance greater than steel. So, it is used to make high-performance
  • Electrical characteristics: Fiberglass is a good electrical insulator even at low thickness.
  • Incombustibility: Since fiberglass is a mineral material, it is naturally incombustible. It does not propagate or support a flame. It does not emit smoke or toxic products when exposed to heat.
  • Dimensional stability: Fiberglass is not sensitive to variations in temperature and hygrometry. It has a low coefficient of linear expansion.
  • Compatibility with organic matrices: Fiberglass can have varying sizes and has the ability to combine with many synthetic resins and certain mineral matrices like cement.
  • Non-rotting: Fiberglass does not rot and remains unaffected by the action of rodents and insects.
  • Thermal conductivity: Fiberglass has low thermal conductivity making it highly useful in the building industry.
  • Dielectric permeability: This property of fiberglass makes it suitable for electromagnetic windows.
  • Operating Temperature: up to 550 C

Fiberglass comes in various forms to suite various applications, the major ones being:


Fiberglass tapes are made up of glass fiber yarns and are known for their thermal insulation properties. This form of fiberglass finds wide applications in wrapping vessels, hot pipelines, and the likes.

  • Thickness: 3 mm
  • Width: 25 mm – 100 mm
  • Packing: 2.5 KG or 5 KG (Dependent on size)

Fiberglass cloth is smooth and is available in various variants like glass fiber yarns and glass filament yarns. It is widely used as heat shields, in fire curtains and others.

  • Thickness: 0.02 mm – 3 mm
  • Width: 1 m
  • Length: 30 m or 50 m

Ropes are braided from glass fiber yarns and are used for packing purposes.

  • Thickness: 3 mm – 50 mm
  • Packing: 5kg or 10 Kg

Fiberglass Tissue is used as a waterproofing and reinforcing agent, as a stabilizing or separation layer, and as a surfacing or acoustic insulation product, and end products include such widely differing products as fitted carpeting, washable wallpapers or bituminous roof shingles.
