What Is Halogen Free Cable?

Does RoHS mean halogen free?

A: No.

A company can’t claim halogen-free status solely due to REACH or RoHS compliance, and will need to comply with halogen-specific standards, such as IEC 61249-2-21 and JS709C, to make such a claim..

What is halogen free flame retardant?

Applications. Flame retardants are substances or compounds that are added to other materials, such as plastics, coatings and textiles to prevent or delat the the spread of fire. The first applications of flame retardants predate the Gregorian calendar.

What does it mean to be halogenated?

Explanation: From the periodic table, the halogens are the group 7 elements. So when something is halogenated, it means the compound contains a halogen ( Ioding, Chlorine, Bromine, Fluorine…)

What cable uses a halogen free jacket material?

What does LSZH mean? LSZH stands for low smoke zero halogen. The compounds in the cable insulation and jacket have no fluorine, chlorine, bromine, iodine, or astatine. This means that the cable emits little to no toxic halogens and minimal smoke when in contact with fire.

Why are halogens dangerous?

Halogens are highly reactive, and as such can be harmful or lethal to biological organisms in sufficient quantities. This high reactivity is due to the high electronegativity of the atoms due to their high effective nuclear charge.

Is XLPE halogen free?

EP8400X125F-3/150F-3 FR XLPE Compounds do not emit halogen acid and produce very low gases, and low smoke under fire condition.

Why is halogen free important?

Low smoke and halogen free products are used to protect wiring, as they are proven to limit the amount of toxic gas emitted when it comes into contact with heat.

Is PTFE halogen free?

By comparison PTFE base materials do not contain bromine and should not be included in the “halogen-free” debate. Fluorine is the most electronegative of elements and forms an extremely strong bond with carbon.

Is XLPE a Lszh?

It also includes low smoke zero halogen single core XLPE/LSZH/AWA/LSZH and multicore XLPE/LSZH/SWA/LSZH with the same voltage ratings….XLPE/LSZH/SWA/LSZH BS6724 cable construction.British Standard BS5467InsulationCross-linked polyethylene (XLPE)BeddingLSZHArmourSWASheathLSZH2 more rows

What is halogen used for?

What are some uses of halogen elements? Chlorine is used to purify water. Chlorine also is part of salt, sodium chloride, which is one of the most widely used chemical compounds. Fluorine is used in fluorides, which are added to water supplies to prevent tooth decay.

Is Polycarbonate halogen free?

Description: Halogen-free Flame-resistant Polycarbonate Film is an ECO-friendly flame-resistant polycarbonate film, free of halogen, limited heavy metals and phosphate flame retardants.

What is meant by halogen free?

The halogen-free material is a material that does not contain a group of halogen elements (fluorine, chlorine, bromine, iodine, and astat). These fire elements release substances that are toxic to humans in the form of toxic fumes but also cause corrosion of metals.

Is XLPE low smoke?

Low smoke zero halogen (hereafter referred to as LSZH but also called LSOH, LS0H, LSFH or OHLS) is a material classification that is common to cable and wire casings. … There are several similar classifications such as low smoke and fume (LSF) and low smoke varieties of PVC and cross-linked polyethylene (XLPE).

What is a low smoke cable?

Low smoke zero halogen or low smoke free of halogen (LSZH or LSOH or LS0H or LSFH or OHLS or ZHFR) is a material classification typically used for cable jacketing in the wire and cable industry.

Are halogens flammable?

Hydrogen halides are formed during combustion of halogen-containing organic compounds. colourless, non-flammable, toxic gas with a pungent smell. Very soluble in water, forming hydrochloric acid and thus a highly corrosive fog in wet air.

Is PVC cable halogen free?

Halogen-free cables are cables whose materials are not processed with the elements of the halogen group. As non-conductors, halogens such as chlorine are excellent insulators and are therefore often used as jacket material for cables. The most common example of this is polyvinyl chloride (PVC).
