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..
Why are halogens so important?
Halogens are highly reactive, and they can be harmful or lethal to biological organisms in sufficient quantities. This reactivity is due to high electronegativity and high effective nuclear charge. Halogens can gain an electron by reacting with atoms of other elements. Fluorine is one of the most reactive elements.
What is halogen free cable?
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.
What halogen is used to kill bacteria?
ChlorineChlorine is a disinfectant – it kills bacteria (see iodine below). It is used to kill bacteria in drinking water and swimming pools.
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 non halogen mean?
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.
What does it mean to be RoHS compliant?
Hazardous Substances in Electrical and Electronic EquipmentRoHS is a product level compliance based on the European Union’s Directive 2002/95/EC, the Restriction of the Use of certain Hazardous Substances in Electrical and Electronic Equipment (RoHS).
What is the purpose of RoHS?
RoHS has its roots in the European Union back in 2003. The goal of RoHS (Reduction of Hazardous Substances) is to reduce the environmental effect and health impact of electronics. The legislation’s primary purpose is to make electronics manufacturing safer at every stage of an electronic device’s life cycle.
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…)
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.
Does RoHS compliant 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 are 3 uses of halogens?
Halogens are used in the chemical, water and sanitation, plastics, pharmaceutical, pulp and paper, textile, military and oil industries. Bromine, chlorine, fluorine and iodine are chemical intermediates, bleaching agents and disinfectants.
