PVC is tough, wear-resistant, flame retardant, soft and hard, squeezable and injection moldable, electrically conductive, insulating and shieldable, and has good mechanical strength. PVC is very resistant to corrosion, impact, abrasion, weathering and even chemical corrosion. And lightweight, reducing the difficulty of manual operation.
Cheap, flame retardant, soft and hard, squeezable and injection moldable, electrically conductive, insulating and shieldable.
Pvc wide application time
PVC (polyvinyl chloride) is widely used for cable insulation, bedding, and sheathing. In the 1950s, PVC processing was more convenient, and PVC cables began to replace rubber-insulated and sheathed cables in ordinary household wires. PVC is cost-effective and has excellent aging properties, typically with a service life of more than 30 to 35 years.
PVC is used as the insulating material, and the cable can usually be selected between XLPE and PVC thermoplastic materials and thermosetting materials. Thermoset or crosslinked PVC has improved temperature resistance, is tougher and has better dielectric strength, and the table name can apply a thinner coating or insulating layer to make the overall cable size smaller.
Environmentally-friendly PVC cable material
In the 21st century, with the increasing awareness of human environmental protection and people’s concern for their own health, environmental issues have become the focus of human society. Many countries, regions, and organizations have set strict standards and regulations to limit the use of harmful substances, especially It is RoHS and reaches.
The EU regulations for products entering the EU countries after July 1, 2006, must comply with environmental protection RoHS regulations. Traditional PVC cable materials do not comply with RoHS regulations because they contain a certain amount of harmful substances such as heavy metal elements and become an important factor restricting the application of PVC wires and cables in electrical equipment, infrastructure, and infrastructure construction.
On October 28, 2008, the EU announced the first batch of SVHC (Substances of Very High Concern) candidate substances list, REACH regulations are officially implemented, all preparations and articles entering the EU will be controlled by this regulation, although the regulations do not prohibit the inclusion of these high Chemicals that focus on substances enter the EU market, all require a comprehensive set of procedures such as registration, evaluation, authorization, and restriction. This has led some EU customers to require the above substances not to be included in the products supplied by their respective suppliers in order to simplify the process. Therefore, it has a significant impact on the production of PVC cable materials. In order to meet the requirements of environmental protection regulations, environmentally friendly PVC cable materials emerged as the times require, and quickly became one of the themes of current PVC cable material development. Environmentally-friendly PVC cable material requirements: low lead and heavy metal content, low smoke, low hydrogen chloride, low toxicity or non-toxic.

Low toxicity and non-toxic
Cable PVC material contains a large amount of plasticizer, non-toxic plasticizer must be used to make non-toxic materials. Therefore, some phosphorus-containing and sulfur-containing plasticizers should be excluded. Other ingredients such as stabilizers, lubricants, antioxidants, fillers, etc. must use non-toxic materials. Therefore, the requirements for such PVC cable materials are higher than those of lead-free and heavy metal-free materials, and the price is naturally more expensive.
