LLFA TAPE™ is a self fusing tape utilised to insulate and seal electrical cable splices where high and low temperature stability is needed, and where moisture, weather and radiation resistance is required.

Mechanically it provides a high tension wrap that creates an enduring seal under extreme environmental conditions. Due to its remarkable properties, it is also used to repair punctured water, air and hydraulic pipes that are subject to pressureand temperature variants.


 
  • Easily applied, durable and resilient
  • Long life in extreme environments
  • Self fusing layers form a compressing sheath
  • Suitable for high voltage insulation
  • Used for sealing, harnessing, waterproofing and UV shielding

Application
LLFA TAPE™ seals by compression. The tape is pulled as tightly as possible around the splice on the first layer, then with minimal tension on successive layers. The tape then amalgamates with itself, and the tension is maintained indefinitely. The quality of this seal does not depend on the surface of the splice, nor does it rely on adhesive. There is no concern over chemical compatibility, cleanliness or surface condition. This tension will alsonot varry due to the effect of heat, humidity, or cold.

Abrasion Resistance
LLFA TAPE™, due to its unique formulation and manufacturing process, isresistant to abrasion and also split propagation. LLFA TAPE™ can be used as a stand alone product, requiring no protective jacketing tape.

Temperature Stability
Other products decrease or lose fusion properties under extreme cold or humid conditions. This is not true of LLFA TAPE™. The applying technician does not have to keep the tape warm in cold conditions or keep it cold in warm conditions.

Ease of Removal
Unlike other jointing solutions, no adhesive is used to maintain the seal. With no sticky residue to clean, LLFA TAPE™ can be removed quickly should re-entry to the joint be required. The use of adhesive in other jointing solutions results in sensitivity to humidity and temperature variations

Fusion
LLFA TAPE™ is an ultra fast self fusing tape. Similar products require a period of time in order to become a homogeneous/solid mass of rubber. With LLFA TAPE™ this happens almost instantaneously. This is an important factor when splicing or protecting a connection that is subject to high humidity or even submergence.

Puncture Repair
The strength of LLFA TAPE™ makes it both a competent insulation solution and an invaluable puncture repair product. A punctured hose or pipe tightly wrapped with LLFA TAPE™ will immediately withstand internal pressure. This pressure will not push between the “fusing layers” because the fusing action takes place so quickly.

Submersion
Rapid fusion allows a newly wrapped splice to be immediately submerged in water. You don’t have to wait a few hours before declaring a circuit, pump motor etc. operable. After you wrap it, you’re ready to go. In addition, LLFA TAPE™ fuses even under cold, hot or moist conditions.


Water Absorption
The specified water absorption for LLFA TAPE™ is less than 0.5%. The MIL spec requirement for most other silicone based products is <3.0%. Based on the extremely low water absorption characteristic of LLFA TAPE™ and its high tensile strength, water or moisture will not absorb throughthe tape or be able to migrate between the cvable jacket and the tape thus maintaining an excellent water tight seal.

Easy Release Liner
LLFA TAPE™ has an easy release liner. This means that you don't have to pick at the liner to try and remove it. It comes off quickly and easily and is not static sensitive like most other products. In addition LLFA TAPE™'s liner is black in color so that is easy to see.
