PVC Electric Cable Environmentally Friendly Requirements
- Jun 12, 2017 -

PVC Electric Cable will be a strong driving cable industry development, enhance the competitiveness of cable manufacturers, and green practice and innovation, the cable industry in the sustainable development of the road more and more stable. In recent years, China's cable companies to PVC Electric Cable, low smoke and halogen-free cable and other directions, as far as possible does not contain lead, cadmium, mercury and other heavy metals, does not contain brominated flame retardants, does not produce harmful halogen gas, Do not produce corrosive gases, burning less heat, do not pollute the soil, etc., PVC Electric Cable will be more favored by the market, in the grid company tender more easily get high orders.

Users of the requirements of environmentally friendly wire and cable, summed up the following points:

1 requires low lead and heavy metal content

As we all know, lead and some heavy metals can adversely affect human health, and in PVC formulations, usually need to mix lead, cadmium, barium and other heavy metal compounds additives. However, since the 90s of last century, some developed countries and large electrical companies have enacted laws and regulations, in the use of PVC wire and cable, there are eight kinds of heavy metal content shall not be greater than the provisions. These new requirements not only bring new business opportunities to wire and cable manufacturers, but also to the PVC cable manufacturers to bring serious challenges.

2 requires its low smoke and low hydrogen peroxide

Good flame retardant PVC cable is a very obvious advantage, but the ordinary flame retardant PVC cable in the fire burning, will release a thick black smoke and a lot of HCI gas, resulting in the fire after the "second Disaster ", seriously affecting the evacuation and fire rescue work carried out. Therefore, in the wire and cable proposed flame retardant requirements at the same time,PVC Electric Cable in some occasions will be further proposed "low smoke" and "low HCI" requirements.

3 requires low toxicity or non-toxic

For some may be in contact with food, blood products, household appliances, medical and health appliances and children's electric toys on the use of cables, in addition to lead-free non-heavy metals, but also requires non-toxic (or low toxicity). That is to say, all the ingredients used in the PVC formulation should be non-toxic. Cable material contains a lot of plasticizer, but the manufacture of non-toxic materials must use non-toxic plasticizer. Therefore, this PVC material requirements than lead-free non-heavy metal materials higher,PVC Electric Cable the price is naturally more expensive.

4 other banned with

At present, the EU is considering the laws and regulations, the following items were restricted to ensure that the wire and cable can be combined with environmental requirements. For example: 1) asbestos; 2) more by biphenyl and its ethers, polybromophenol; 3) polychlorinated biphenyls; 4) short chain (C10 ~ C13) chlorinated paraffin.

As environmental issues become more and more important, many countries have developed various environmental policies, so people are more inclined to use green cables. Low smoke halogen-free flame retardant cable material is one of the more popular environmentally friendly cable. Although China's market demand for green cable growing, but compared with developed countries,PVC Electric Cable China in the relevant policy development and mandatory applications there is still a long way to go, China should improve environmental cable standards as soon as possible.
