Material: Mineral fiber

Specification: 1-3mm

Product Category: Fireproof Expantrol Self-sealing Material

This product is activated at temperatures above 190℃, resulting in unidirectional expansion of the intumescent mat to form a stable inert char. Highly stabilised by the matrix of mineral fiber, the char acts as an insulating layer, offering enhanced fire protection to the underlying materials.

GT Fireproof Intumescent materials provide highly effective passive fire protection solutiions for a broad range of applications, including lamps, fire door and windows of construction gap filling, composite fabrications, etc. Main properties:

1.High expansion ratio: 4.5:1 up to 35:1

2.It has certain stickiness when expansion under fire, and won’t be flame away, resulting with good sealing effect.

3.It is available in wide range of thickness, offering various expansion volume and pressure characteristics. We customize various specification to reduce users’ production loss, typically supplied as: Sheets, rolls, narrow coils or cut shapes.

4.Passive fire protection: it is not fire extinguishing, it’s used to occasion of fire has occurred, by controlling the spread of fire, to prevent the loss of life and property. Due to public safety, the main index of passive fire protection system is to resist and delay the fire spread time. For example, the intumescent strip installed in fire door or damper will expand soon when get fire, to prevent fire and smoke spread to other parts of the building.

Its unidirectional expansion makes it the ideal fire protection solution for a board selection of traditional gap filling applications. These include:

Pipe wraps and collars

Door edge seals

Glazing seals

Joint seals for building panel systems

Grilles and vents

Ironmongery protection

Linear gap seals
