Into the 21st century, with the enhancement of human environmental awareness and people's concern for their own health, environmental issues have become the focus of human society, many countries, regions and organizations have formulated stringent standards and regulations, to limit the use of harmful substances, especially the RoHS and reach regulations. EU requirements to enter the EU after July 1, 2006 products must comply with environmental RoHS regulations.
The traditional PVC cable material, which contains a certain amount of heavy metal elements and other harmful substances, does not conform to the RoHS regulations, and becomes an important factor restricting the application of PVC wire and cable in electrical equipment, infrastructure and construction. October 28, 2008, the European Union announced the SVHC (high concern substance) The 1th batch of candidate material list, the REACH law is formally implemented, all the products into the EU and articles will be controlled by this regulation, although the law does not prohibit the use of these substances of high concern to enter the EU market, but all need to register, A comprehensive set of procedures for evaluation, authorization, and limitation. This has led some EU customers to simplify the process and require their suppliers to provide products are not allowed to contain the above substances. Therefore, the production of PVC cable material has a significant impact. In order to meet the requirements of environmental protection laws and regulations, environmental protection PVC cable material came into being, and quickly become one of the themes of PVC cable development. Environmental protection PVC Cable material requirements: lead and heavy metal content low, low smoke, low hydrogen chloride, low toxicity or non-toxic.
