PVC Electric Cable Good Flame Retardant Properties
- Jul 25, 2017 -

At present, developed countries are strictly prohibited to use non-environmentally friendly cable, China also attaches great importance to this area. China's relevant laws and regulations stipulate that important buildings prohibit the use of PVC wire and cable, must use halogen-free low smoke cross-linked PVC wire and cable to avoid a large number of smoke when the smoke, chlorine, causing casualties.

PVC Electric Cable  is not containing lead, cadmium, hexavalent chromium, mercury and other heavy metals, does not contain brominated flame retardants, SGS recognized by the testing of environmental performance testing, in line with the EU Environmental Directive (RoSH) and higher than its requirements The Does not produce harmful halogen gas, does not produce corrosive gases, burning less heat, do not pollute the soil of the wire and cable.

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.

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.

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, in some occasions will be further proposed "low smoke" and "low HCI" requirements.

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, the price is naturally more expensive.     

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.
