ATP's low smoke zero halogen materials support the wire and cables to pass the CPR EN grade (B2ca, Cca, Dca, Eca) burning test;
The LSZH jacket material has a higher flame retardant grade and drop test grade, and still has excellent processing characteristics and quality under the condition of high flame retardant performance;
ATP's High Voltage LSOH LSZH Cable Jacket Material Solution, Fully meets the low friction LSZH requirements of temperature resistance, flame retardant, and other indicators of high-voltage wire harness passing ISO 125 &#; and ISO 125&#; tests.
ATP's low smoke zero halogen material with good process-ability, fully meet the requirements of high-speed extruding, line diameter rounded and stable, less salivation(less die stock). The low smoke zero halogen material is also with good color stability, and higher yield rate.
LSZH compound is a kind of cable sheathing material that has been widely used in the world. The urgent need of cable manufacturers is to provide better scale processing and better prices while meeting the basic safety performance, flame retardant performance, mechanical strength, and reliability. ATP's Defender-N&#; LSZH jacket material product is a cost-effective low friction LSZH material developed for this customer's needs.
After the low-smoke zero halogen flame retardant compound polyolefin cable material is cross-linked, it can improve the mechanical properties, heat resistance, environmental stress cracking resistance, and other properties of the material, broaden the application scope of the material, and improve the reliability and life of the material according to low smoke zero halogen regulations.
LSZH materials are used in various applications where smoke emission and toxicity caused by burning of the materials can be a safety hazard, such as in aircraft, trains, ships, data centers, and public spaces.
LSZH materials are made from special polymers that contain no halogenated additives, which are responsible for producing smoke and toxic fumes when the material is burned. Instead, LSZH materials are formulated with fire retardant chemicals that reduce the amount of smoke and toxic gases emitted during a fire.
LSZH materials are preferred in situations where human safety is of utmost importance, as well as in settings where sensitive electronic equipment is present, as smoke and corrosive gases can damage electronic components. LSZH materials are also more environmentally friendly compared to traditional halogenated materials, as they release fewer harmful substances into the environment when burned.
Low Smoke Zero Halogen (LSZH) materials are used in a variety of applications where the release of smoke and harmful gases could pose a threat to human life or equipment. Here are some benefits of this material:

Less Toxicity: LSZH materials contain no halogens, which are known to emit toxic gases when burned. This makes them ideal for use in confined spaces such as aircraft cabins, submarines, and underground tunnels where the accumulation of toxic gases can pose a serious risk to human life.
Increased Safety: In addition to reducing toxicity, LSZH materials also reduce the amount of smoke produced during combustion. This helps to minimize the risk of smoke inhalation, which can cause serious health problems and impair visibility in emergency situations.
Improved Equipment Protection: LSZH materials are also beneficial for protecting equipment in the event of a fire. Since they produce less smoke, they can help to prevent smoke damage to sensitive electronic equipment, which can be costly to replace.
Environmental Friendliness: LSZH materials are also environmentally friendly, as they do not emit toxic gases when burned. This makes them a good choice for use in applications where sustainability and eco-friendliness are important considerations.
Compliance with Regulations: Many industries, including aerospace, transportation, and telecommunications, have regulations that require the use of LSZH materials in certain applications. Choosing LSZH materials can help ensure compliance with these regulations and avoid costly fines or other penalties.
LSZH materials are typically based on polyolefin plastics. Other common terms for LSZH are LSOH (low smoke zero halogens), LSNH (low smoke no halogens), LSHF (low smoke halogen-free) and FRNC (frame retardant non corrosive). FRNC is often divided into FRNC-B and FRNC-C. The suffixes &#;B&#; and &#;C&#; denote the test regime specified in the German standard DIN VDE Part 804. With &#;B&#; just one individual cable is tested, with &#;C&#; a cable bundle which makes it a more strict regime than &#;B&#;.
LSZH materials are more expensive than PVC. They are made for indoor applications and in special versions also for outdoor use, however direct burial is not recommended due to permanent humidity. LSZH materials are less flame retardant than PVC but emit only little and light smoke when burning, which means people should be able to find the emergency exits in case of fire. As LSZH compounds contain no halogens (fluorine, chlorine, bromine, iodine) they do not emit any of these as a corrosive gas when burning. Cable with an LSHZ jacket can be handled nearly as easily as with a PVC jacket, however they are not resistant against water, oil and grease. They can typically be used from -30 °C to + 60 °C. Cables with an LSHZ jacket are typically common in Europe.
