How to pick the right intumescent for you

How to pick the right Intumescent for your project

Intumescents are technologically advanced passive fire protection materials. Intumescents are typically used in construction to maintain or reinstate the fire resistance of buildings, in floors, walls and ceilings.

When planning the construction of a building the integrity of structures needs to be considered. Penetrations such as pipes, ducting, lighting, electrical sockets are all places that fire can use to spread through buildings. Intumescents will expand to close off the penetration and block the spread of fire, smoke and excessive heat.

Tenmat supplies a range of intumescent materials, each has different characteristics which makes them suitable for different applications. It’s important to use the best suited material for your application as the reaction to fire can be different, leading to potential injury or structural damage.

FF102

This is a rigid intumescent that possesses excellent pressure generation and expansion performance. It is a halogen free, graphite based intumescent which produces a particularly stable and resilient insulating char structure during and after expansion.

Key applications

Open state cavity barriers
Door and glazing applications
Iron monger protection
Firestop systems for ventilation
General gap sealing

FF102B

This is also a rigid intumescent, as above and is most commonly used as the intumescent core within air transfer grilles, to maintain fire compartmentation in timber fire doors.

FF107

This is an exceptionally powerful intumescent which combines fast reaction with high expansion and pressure generation. This material produces a solid char of integrity when in a fire situation.

Key applications

Open state cavity fire barriers
Penetration seals
Pipe wraps
Duct fire wraps
Fire collars
Electrical socket protection
Gap sealing

FF160

Firefly 160 is an industry leading intumescent materials developed to provide outstanding expansion characteristics combined with exceptionally solid and durable char structure. It retains fast reaction and high pressure generation characteristics whilst also offering a high level of controlled multi-directional expansion. The resulting performance is ideally suited to the more onerous European (EN) Fire Testing of pipe penetrations where uncapped/ Uncapped (U/U) testing is required.

Key applications

Service penetration seals
Fire wraps
Fire collars
Fire curtains
Construction joint seals
Gap sealing applications

FF104E

This material generates high expansion and pressure generation when exposed to fire or heat. It is created in a very low thickness and easy characteristics make it ideal as a thin intumescent gasket material where space is a premium. It’s supplied in rolls for easy use on site.

Key applications

Fire door and glazing seals doors hardware
Ironmongery protection damper seals
Electrical socket protection
Gap sealing
Gasket applications

FF108

If you are looking for a low density, compressible intumescent materials which exerts relatively low pressure and free expansion characteristics. The low pressure and free expansion characteristics. The low free expansion ensures and extremely solid and stable char structure is produced. The material can be vacuum formed into a variety of shapes as well as being produced in sheet form.

Key applications

Expansion joint seals
Cable basket protection
Fire stop blocks

FF109

109 is a highly compressible intumescent material which expands to form a resilient and stable char, the material is available in sheets or formed shapes.

This is a lower density material with mid-range expansion characteristic, this allows the material to function in a controlled manner without the need for additional restraints.
