What is halogen free wire?
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).
What cable uses a halogen free jacket material?
LSZH wire and cable are also called: low smoke non-halogen (LSNH), low-smoke halogen-free (LSHF), and low-smoke zero-halogen (LS0H).
Is silicone cable halogen free?
Silicone cables are halogen-free cables and are especially suited for installation in power stations.
What is halogen in cable?
Halogens are a group of elements that include fluorine, chlorine, iodine, and bromine. They’re all volatile materials that are highly reactive to other substances. For years, halogens have been used in cables for various reasons, including low cost and high heat resistance.
Is halogen free required?
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.
Is halogen free cable low smoke?
HF = Halogen free. LS = low, limited smoke. FRLS = fire resistant, low smoke.
Is PVC cable halogen free?
PVC or polyvinyl chloride is not a halogen-free material because it contains chlorine.
Is PE halogen free?
Polymers like polyethelene (PE) or polypropylene (PP) are halogen-free. These materials are easy flammable and not self-extinguishing.
What products contain halogens?
Modern utilization of halogens is extensive. They are used in swimming pools (chlorine and bromine), drinking water (chlorine and fluorine), toothpaste (fluorine) as well as in table salt (chlorine). Apart from astatine, traces of halogens can be found in the human body and are considered essential for good health.
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 cable is non toxic if insulation is burned?
Low smoke zero halogen cable insulation
Low smoke zero halogen cable insulation and jacket have no fluorine, chlorine, bromine, iodine or astatine, so they do not emit toxic or corrosive fumes and create minimal smoke when fire is present.
What does low halogen mean?
Within Intel, the term “low-halogen” is defined in Clause 4 of JEDEC JEP 709 and is used to identify solid state devices that contain low concentrations of bromine and chlorine from brominated and chlorinated flame retardants (BFRs, CFRs).
What are examples of halogens?
halogen, any of the six nonmetallic elements that constitute Group 17 (Group VIIa) of the periodic table. The halogen elements are fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and tennessine (Ts).
How do you identify halogens?
Halogen in an organic compound is detected by Carius method. A known mass of an organic compound is heated with fuming nitric acid in presence of silver nitrate contained in Carius tube. Carbon and hydrogen are oxidized to carbon dioxide and water. The halogen present forms silver halide, that is finally weighed.
What is difference between flame resistant and flame retardant?
Resistant is defined as a material that is inherently resistant to catching fire (self-extinguishing) and does not melt or drip when exposed directly to extreme heat. Retardant is defined as a material that has been chemically treated to self-extinguish. There are many textiles that can be “treated”.
How do halogenated flame retardants work?
During a fire, halogenated flame retardants thermally degrade, releasing hydrogen chloride and hydrogen bromide that react with the free radicals in the flame.
What is halogen free plastic?
A cable is halogen-free if no halogens such as chlorine, fluorine or bromine are used in the cable’s insulation and sheath material. Cable glands, hose systems, connectors or shrink hoses, such as the PROTECT HF shrinking tube from LAPP, can also be made of halogen-free plastics and are thus halogen free.
What are 3 uses of halogens?
What are 3 useful applications of halogens
- Fluorine is used in the manufacturing of toothpaste.
- Chlorine is used in the purification of water.
- Bromine is used in the production of photographic films as well as pesticides and fumigants.
Why is breathing a halogen harmful?
Exposure to halogens, such as chlorine or bromine, results in environmental and occupational hazard to the lung and other organs. Chlorine is highly toxic by inhalation, leading to dyspnea, hypoxemia, airway obstruction, pneumonitis, pulmonary edema, and acute respiratory distress syndrome (ARDS).
