Preflexibel produces all its conduits with high quality polypropylene which guarantees a superior quality for an easy installation. Besides delivering stable quality, offering safety is one of our other main priorities. Therefore we have improved the unique Preflex formula. Now we produce all our conduits halogen free and low smoke (according to IEC 60754-2 and 61034-2).

WHY HALOGEN FREE?

- To enhance the overall fire safety of electrical installations

WHERE'S THE DANGER IN USING MATERIAL WITH HALOGENS?

Halogens are chemical elements which, during combustion, can:

- Spread extremely harmful fumes:

During combustion the chemical combinations become instable and fall apart into halogenous compounds. Chlorine and hydrogen change into hydrogen chloride. When exposed to humid air the hydrogen chloride transforms into hydrochloric acid. Inhalation of this highly corrosive gas causes severe damage to the bronchial tubes.

- Attack building components and computer technologies

When exposed to humid air, hydrochloric acid gases become electrically conductive which causes short-circuits and irreparable damage to electrical appliances. In extreme situations even concrete constructions can be affected, become instable and collapse.

- Cause casualties

Halogens emit toxic gases such as carbon dioxide (CO2) and carbon monoxide (CO). These gases break down the oxygen very rapidly which can cause suffocation.

PREFLEX OFFERS IMPORTANT ADVANTAGES FOR ENHANCED FIRE SAFETY OF YOUR ELECTRICAL INSTALLATION:

- Less toxic gases can save lives and are less harmful for the environment, buildings and technical infrastructures.

- Less smoke makes the job of fire fighters and rescue services easier and safer.

Preflex conduits comply with the low smoke directive IEC 61034. This European directive attends to the density of smoke originated by the combustion of materials. According to this directive the visibility may never become less than 60%. The tests executed on Preflex conduits show a preservation of no less than 94% of the visibility.

- Flame retardancy prevents the spreading of the fire.

- If you want an electrical installation that complies with the highest standards of fire safety, use our halogen free conduits in combination with halogen free cables! A complete range of halogen free cables is available*!

HALOGEN CONTENT OF FLEXIBLE PIPES

HALOGEN CONTENT OF FLEXIBLE PIPES, Preflex

In fire safety the first priority is common sense. The use of the right, fire safe materials is very crucial. At an intervention, for us, the most complicating element is the smoke. It doesn’t only reduce the visibility, but the smoke can also be very poisonous and cause great danger both to ourselves as to the victims in the fire.

HALOGEN FREE, WHAT DOES THAT MEAN?

The Preflex halogen free conduits comply with the European directives IEC 60754-1 and 60754-2:

These directives state that the degree of acidity of gases evoked by combustion of halogen free materials may not exceed a certain limit. The average pH value of the evoked gasses may not be lower than 4,3 and the conductivity may not be higher than 10ųS/mm.
