Characteristics

PGT.3/ROS Pyrotapes are very flexible, specifically designed to protect wires, cables, and hoses from high ambient temperatures.

• Continuous protection at an operating temperature of 260ºC
• Ability to withstand a molten metal splash at 1200ºC
• Excellent flame resistance
• Provides personnel protection against burns from hot hoses, steam lines, etc.
• Helps to reduce energy loss by retaining heat within pipework
• When exposed to flame the high grade silicone elastomer will form a protective SiO2 layer
• Highly resistant to most oils, hydraulic fluids, fuels, acids, and alkalis
  
• Good abrasion resistance
• High flexibility

When should I use PGT.3/ROS Pyrotape instead of a silicone coated glass fibre firesleeve?

The choice often comes down to how the product needs to be installed.

A silicone coated glass fibre firesleeve is a tubular product designed to surround a hose, cable, wire or pipe, providing continuous protection around the component. It is generally installed before the hose or component is connected.

PGT.3/ROS - Pyrotape is supplied as a flexible tape that can be wrapped around existing hoses, cables, pipework and other components. This makes it particularly useful where a conventional firesleeve cannot be fitted, where an assembly is already installed, or where additional protection is required around a specific area.

Both products use the same basic principle of combining glass fibre thermal resistance with silicone elastomer protection, but their different formats make them suitable for different installation requirements.

When choosing between a tape and a firesleeve, consider the component geometry, accessibility, installation method, temperature, exposure conditions and the level of protection required.

What is the advantage of silicone coated glass fibre tape over uncoated glass fibre tape?

Both silicone coated glass fibre tapes and uncoated glass tapes can provide high-temperature protection, but the silicone coating gives the glass fibre additional properties that can be important in demanding industrial environments.

The silicone elastomer coating provides greater resistance to abrasion, oils, hydraulic fluids, fuels and other environmental contaminants, while maintaining the flexibility required for wrapping around components.

PGT.3/ROS Pyrotape is therefore a useful choice where protection from heat needs to be combined with protection from the surrounding working environment.

This makes silicone coated glass fibre tape particularly suitable for applications such as hydraulic systems, industrial machinery, steel processing, foundries and other high-temperature industrial environments.

Can PGT.3/ROS Pyrotape be used to protect hydraulic hoses from heat and abrasion?

Yes. PGT.3/ROS Pyrotape is particularly useful where hydraulic hoses need protection from a combination of heat, radiant heat, abrasion and hydraulic fluids.

The flexible red oxide silicone coated glass tape can be wrapped around the hose to provide a protective thermal barrier, while the silicone coating provides additional resistance to abrasion and environmental contamination.

As with any hose protection product, the tape should be selected and installed according to the hose diameter, heat source, exposure conditions and level of protection required.



One of the advantages of PGT.3/ROS Pyrotape is that it can be wrapped around an existing hose assembly, making it useful where a tubular firesleeve cannot easily be fitted or where the assembly cannot be disconnected.

Why is PGT.3/ROS Pyrotape rated for 260°C continuous exposure but up to 1200°C for molten metal splash?

These two temperature ratings refer to very different types of heat exposure.

The 260°C rating relates to continuous exposure to elevated operating temperatures.

The 1200°C rating relates to short-duration exposure to molten metal splash, where extremely high temperatures are encountered for a much shorter period.

This means PGT.3/ROS Pyrotape can be used to provide ongoing thermal protection around components operating in hot environments, while also providing protection against brief, severe heat events such as molten-metal splash.

It is important to remember that 1200°C is not a continuous operating temperature for the Pyrotape or for the component being protected. The actual protection achieved will depend on the application, exposure conditions, installation and duration of the thermal event.

What happens to the silicone coating when PGT.3/ROS Pyrotape is exposed to high temperatures or flame?

When silicone is exposed to high temperatures (300°C - 500°C), the organic part of the silicone elastomer gradually breaks down, leaving behind a heat-resistant silica (SiO₂) residue.

This silica layer helps to protect the glass fibre substrate and contributes to the tape's ability to withstand intense heat and flame exposure.

This is particularly important where PGT.3/ROS Pyrotape is being used for flame protection, radiant heat protection or molten-metal splash protection. The silicone coating and glass fibre substrate work together to form a protective thermal barrier.

The temperature and duration of exposure are important when assessing performance, so the continuous operating temperature should not be confused with the tape's ability to withstand short-duration extreme heat.

Why is PGT.3/ROS Pyrotape made from E-glass fibre with a red oxide silicone coating?

PGT.3/ROS Pyrotape combines the high-temperature performance of E-glass fibre with the flexibility and protective properties of a high-grade silicone elastomer coating.

The distinctive brick-red colour of PGT.3/ROS Pyrotape comes from an iron oxide pigment incorporated into the silicone coating, giving the tape its characteristic red-oxide appearance.

The E-glass fibre provides the underlying high-temperature (600°C) textile construction, while the silicone coating helps protect the glass fibre from abrasion and the surrounding environment. The silicone elastomer also provides resistance to many oils, hydraulic fluids, fuels, acids and alkalis.

Together, these materials create a flexible silicone coated glass fibre tape that provides thermal, mechanical and environmental protection. This makes PGT.3/ROS particularly suitable for demanding industrial applications where an uncoated glass fibre tape may not provide the combination of protection and durability required.
