FCL Intumescent Tape - Black (1mm x 25mm x 10m)

Colour: Black

Tecnofire® intumescents are available in a wide range of thicknesses and with various expansion volume and pressure characteristics. The Tecnofire® range includes both flexible and rigid products. Tecnofire® intumescents can be supplied in sheets to customers required dimensions, in large rolls, in narrow coils slit to required width or die cut to any required shape.
All grades of Tecnofire® can be supplied with self adhesive backing. Self adhesive backing is a two stage process. The surface of the Tecnofire® is sealed with a primer then self adhesive coating and release paper is applied. This results in a self adhesive
backing with high tack and minimises the risk of product delamination during use.
The surface of flexible grades of Tecnofire® can be coated to improve abrasion resistanceand appearance. The standard
coating used is black but other colours are possible

Smoke Emission

Products have been tested to BS6853: 1987 Appendix B. Clause B5.1 - Fire Precautions in the Design and Construction of Railway Passenger Rolling Stock, Three Metre Cube Smoke Emission Test. The recommended compliance criterion for Category
1 material (described as ‘Rubber/Plastics: solid, or flexible cellular’) is an Ao value of less than 0.02. The products tested meet this criterion.

Smoke Toxicity

Tecnofire® intumescents are formulated to minimise the generation of toxic fumes under fire conditions. Various grades have been tested to recognised standards and reports are available. Test results include: DIN 53436. Analysis of gases resulting from combustion at 600oC. The total yield of carbon monoxide produced by the products tested was in the range 19.09mg/g to 20.19mg/g. Cyanide, nitrate, sulphate, fluoride, chloride and bromide ions were all below detectable limits. Naval Engineering Standard 713: Issue 3 - Determination of the Toxicity Index of the Products of Combustion from Small Specimens of Materials. Typical toxicity index 1.21. London Underground Ltd Engineering standard E1042: A2: March 1998. Quantitative analysis results for carbon, aluminium, silicon, sulphur, calcium, titanium, iron and chromium are available.

Surface Spread of Flame and Fire Propogation

Test results to BS476 Part 6 and Part 7 are available for certain Tecnofire® products on request.

Product Stability

With the exception of Tecnofire® 2000, Tecnofire® intumescents have not been designed for full external exposure conditions and cannot be guaranteed for use in such situations. However, all Tecnofire® intumescent products have considerable tolerance to damp conditions and occasional water immersion such as might occur from condensation, leaking pipes, floods or similar events in a building. Tests have shown that, after water immersion, Tecnofire® intumescents will dry out and give the same level of performance as the original sample. Further details of resistance to water and chemicals for various Tecnofire products are available on request. Tecnofire® 2000 is impregnated with a thermoset epoxide resin which results in a hard, durable and vandal resistant surface. The product has a high degree of water and chemical resistance.
