What are the differences between ordinary materials and environmentally friendly materials of PVC coated steel wire rope?

The main difference between the ordinary material and the environmentally friendly material of PVC coated steel wire rope lies in the composition of the coating layer (PVC outer layer) and the additives added. The following are the detailed differences:

1. Material composition:

Ordinary PVC coating:
The main component is polyvinyl chloride (Polyvinyl Chloride). Some additives are usually added during the production process, such as phthalate plasticizers, stabilizers (which may contain heavy metals such as lead and cadmium), flame retardants, etc., to improve its flexibility, weather resistance and processing performance.

Environmentally friendly PVC coating:
The PVC resin itself of environmentally friendly material PVC coating may not be essentially different from ordinary PVC, but the key lies in the additives used. Environmentally friendly PVC will avoid or use safer alternatives to replace harmful substances, for example: using environmentally friendly plasticizers: such as epoxy soybean oil, citric acid esters, etc., to replace phthalate plasticizers to reduce potential harm to the human endocrine system.
Use non-toxic or low-toxic stabilizers: Avoid using stabilizers containing heavy metals such as lead and cadmium, and turn to more environmentally friendly systems such as calcium zinc and organic tin.
Use environmentally friendly flame retardants: Choose flame retardants that do not contain harmful halogens.

2. Environmental performance:

Ordinary PVC plastic coating:
May contain harmful substances: Phthalate plasticizers are considered to affect the human endocrine system, especially potential risks to children's health.
Heavy metal pollution risk: Stabilizers containing heavy metals such as lead and cadmium may cause environmental pollution during use and disposal.
Combustion produces harmful gases: PVC releases corrosive and toxic gases such as hydrogen chloride when burned, and may produce carcinogens such as dioxins.
Difficult to degrade: PVC is a difficult-to-degrade plastic. After being discarded, it exists in the environment for a long time, causing white pollution.

Environmentally friendly PVC plastic coating:
Reduce or do not contain harmful substances: The use of environmentally friendly additives greatly reduces or avoids the content of harmful substances such as phthalates and heavy metals, which is more friendly to human health and the environment.
Less harmful substances produced by combustion: Even if burned, since it does not contain harmful additives, the harmful gases produced are relatively small (but PVC itself will still produce hydrogen chloride when burned).
Easier to recycle and handle: Some environmentally friendly PVC materials may be easier to recycle and reuse, or adopt more environmentally friendly treatment methods.

3. Application areas:

Ordinary PVC plastic coating:
Due to its relatively low cost, it is widely used in various fields, such as ordinary clotheslines, industrial ropes, construction ropes, low-requirement protective ropes, etc.

Environmentally friendly PVC plastic coating:
Due to its relatively high cost, it is usually used in fields with higher requirements for environmental protection and health, such as: children's products, toy-related wire ropes.
Medical equipment, food contact-related equipment ropes.
Indoor fitness equipment, household items and other fields that focus on health and safety.
Some products exported to countries and regions with high environmental standards.

4. Cost:

Ordinary PVC plastic coating:
The production cost is relatively low, so the price is also more economical.

Environmentally friendly PVC packaging:
Due to the use of more environmentally friendly raw materials and additives, the production cost is usually higher, so the price is relatively high.
