Analysis of main materials used in cable industry
May 17, 2018

The use of stabilizers, plasticizers and a variety of fillers and other additives in the environmental protection of different. is generally RoHS or reach detection methods and standards to measure, divided into environmentally friendly and environmentally-friendly PVC cable materials. Because the structure of wire and cable is very similar, and very simple, conductive wire core insulation and sheath more by plastic or rubber coated.

The user chooses the model and the specification according to the use and the layout environment, the production plant then chooses the material and the manufacturing craft according to the related standard. At present, plastic accounts for 91% of the coating material, and PVC accounted for 80% of the plastic. Other information shows that in the United States, plastic accounted for the wire and cable industry coating materials 85%, of which PVC accounted for 60% of the plastic.

PVC is a chlorine-containing polymer, has good flame-retardant properties and cable production and use of a variety of performance requirements, low price, is the world's most widely used plastics.

With the enhancement of people's environmental awareness and sustainable development concept, there are many disputes about the environmental pollution of plastics and whether PVC should be banned, but the production and usage of polyvinyl chloride is increasing, which is especially evident in China.

With the development of science and research in-depth, so many environmentally friendly PVC products have been developed, wire and cable is also well received, and environmentally friendly PVC wire and cable supporting environmentally friendly PVC cable materials in recent years the rapid development is a proof. Users of PVC wire and cable environmental protection requirements and environmental protection PVC cable material development when the cable material is successfully prepared, to RoHS or reach detection methods and standards in the ICP Test equipment test, all the material components of heavy metal content, DEHP, nonylphenol, PBBs and other banned substances and controlled substances,

Because each country's requirements for the content standard are not the same, the corresponding environmental standards are different. Test units are generally measured in 10-6. Environmentally friendly cable materials stabilizer is generally the use of calcium and zinc stabilizer.

The most important thing to meet the REACH standard PVC cable material is not to use 16 kinds of substances such as DEHP to make plasticizers.

Non-environmental protection cable materials generally use lead salts to do stabilizer, because it contains heavy metals such as lead, chromium, cadmium, mercury, barium and other heavy metals, will cause great harm to the environment and human health, and more and more countries are restricted or prohibited use. In the lower voltage (1 K V) of the line and electrical equipment used in the wire and cable, the insulation and sheath can be PVC coated, while medium and high pressure (greater than 6 K V) of the sheath of wire and cable most of the use of PVC coated.
