Ceramic Fibre Lagging Rope | Fibreglass Knitted Rope with Core | Fibreglass Medium Rope | Fibreglass Braided Round | Fibreglass Square Rope | Braided Rectangular | Ceramic Fibre Square | Ceramic Fibre Round | Tadpole Tape/Rope | E Glass Yarn

Thermal fiberglass rope is used for high-temperature sealing, gasketing, and insulation in both domestic and industrial settings.

  • Acting as an asbestos replacement for sealing doors on wood/coal stoves, furnaces, boilers, ovens, and for pipe lagging, expansion joints.
  • Also, for pollution control equipment due to its flexibility, durability, and resistance to heat.

 Key Applications

  • Seals & Gaskets: Door seals for wood stoves, ovens, furnaces, and boilers; seals for expansion joints, filters, and duct flanges.
  • Insulation: Lagging (wrapping) pipes, tanks, and valves to retain heat.
  • Industrial Packing: Sealing mechanical components like pumps, valves, and rotary equipment in harsh environments.
  • Caulking: Filling grooves and gaps in high-temperature applications.
  • Specialty Uses: Core material for tadpole tapes and gaskets, seals for hot air hoods, and in refractory environments. 

Key Properties

  • High Heat Resistance: Withstands continuous temperatures up to around 540°C (1000°F).
  • Flexibility: Easily conforms to tight corners and channels.

  • Durability: Resistant to moisture, chemicals (mild acids/alkalis), and steam.
  • Asbestos Replacement: A safer alternative to asbestos in many applications

TADPOLE TAPE / ROPE

Tadpole tape is a specialized thermal gasketing used to create high-temperature seals on doors, access ports, and flanges for equipment like furnaces, ovens, boilers, and wood stoves.

  • preventing heat and gases from escaping by using a compressible bulb for sealing and a tail for attachment
  • available in various heat-resistant materials. 

Applications

  • Sealing Doors & Access Points: Its primary function is sealing openings on industrial ovens, furnaces, incinerators, kilns, and even domestic heaters.
  • Flange & Gasketing: Used as a gasket where low bolt force is applied, such as on crucible lids or ladle seals in aluminum casting.
  • High-Temperature Environments: Ideal for containing hot gases and providing insulation in extreme heat, often up to 1000°F (538°C) or higher depending on the material. 

How it Works (Bulb & Tail)

  • The Bulb: A dense core (fiberglass, ceramic, or metal mesh) wrapped in fabric that compresses under pressure to form an airtight seal.
  • The Tail: A flexible strip that extends from the bulb, used to fasten the tape in place with fasteners, clips, or adhesive. 

Materials & Types

  • Materials: Commonly made from fiberglass, silica, or ceramic fibers for high heat resistance, with cores of stainless steel or Inconel.
  • Styles: Available in different configurations, including conventional (centered tail), tangential (tangent tail), and double-tail designs
