The material of a cable has a decisive influence on its quality. In the past, plastic cables were the dominant choice. In recent years, However, THE rubber cables gradually imposed themselves. However, rubber cables are not always the best choice. In this article, We will examine the difference between rubber cable and plastic cable so that readers can better understand their properties and applicable scenarios.
The Ddifference between the Crubber and the Pelastic
Generally speaking, rubber is a type of plastic, and plastic includes rubber.
The most essential difference between plastic and rubber is that plastic deforms elastically when deformed, while the rubber deforms elastically. In other words, plastic is not easy to return to its original state after deformation, while rubber is relatively easy to return to its original state.
Differences of Structure Chimic
The most fundamental difference between plastic and rubber is their molecular structure and chemical properties. Plastics are generally made of polymers, and the bonds between these polymer chains are weak. Therefore, plastics deform elastically when force is applied.
On the other hand, rubber has a reticulated structure, with strong cross-linking bonds forming between molecules, which allows it to deform elastically when a force is applied, but it can return to its original shape quite easily.
Therefore, although plastics and rubbers are both elastic, there are significant differences in their elastic properties and resilience, which is one of the main differences in their application and performance in cable manufacturing.
Plastics have very low elasticity, generally less than 100 %, while rubber can have an elasticity of 1 000 % or more. Most of the plastics molding process is done as the product is molded. Rubber, as for him, must be vulcanized after the molding process is completed.
Plastic and rubber belong to the same polymer materials, mainly composed of carbon and hydrogen atoms. Some also contain small amounts of oxygen, nitrogen, chlorine, of silicon, but fluorine, sulfur and other atoms.
Differences of Pproperties Physics
Their properties are particular, just like their uses. At room temperature, the plastic is solid, dur, cannot be stretched or deformed. Rubber, as for him, is not hard and is not elastic. It can be stretched and lengthened, stop stretching and return to its original shape. This is because they have different molecular structures..
Another difference is that plastic can be recycled and reused several times. Rubber, as for him, cannot be recycled directly and can only be made into recycled and reused rubber. The shape of the plastic between 100 et 200 degrees is similar to that of rubber between 60 et 100 degrees. Plastics do not include rubber.
Profile of’Aapplication of Crubber for Fthey and Câble not Ppolyethylene Cchlorosulfonated
Type d’Application
Chlorosulfonated polyethylene (CMS) is a derivative of polyethylene. Depending on the chlorine content and molecular weight of the polyethylene, chlorosulfonated polyethylene rubber is available in CSM-20, CSM-30, CSM-40 and CSM-45. CSM-20 and CMS-40 are commonly used in the wire and cable industry.
Features
1) Good physical and mechanical properties. 2) Good heat resistance.
2. Good heat resistance, can be used continuously at a temperature of 120 ℃. 3.
3. Excellent resistance to ozone, in the sunlight, to atmospheric aging, on outdoor exposure for six years without cracking.
4. good flame retardant properties, second after fluoroelastomer and neoprene.
5. excellent resistance to chemicals
6. good oil resistance
7. good resistance to corona effect and radiation
8. good processability and possibility of use with other rubbers.
Disadvantages of chlorosulfonated polyethylene rubber are slightly greater compression distortion and poorer low temperature performance. However, because of its advantages, it is a promising rubber among synthetic rubbers.
CMS-40 is commonly used for insulation and sheathing, and CMS-20 can be used for insulation low voltage wires.
Son and Câble not Celacouc Sicon
First of all, silicone rubber is a special rubber, special in that it is very heat resistant.
Its resistance to heat is due to the fact that its molecular chain is made up of bonds (-And-O-), the binding energy of the silicon-oxygen bond being much greater than that of the carbon bond, which is 443kJ/mol. Si is a non-combustible element, and it has the characteristics of an inorganic material, so its heat resistance is very high.
Advantages of Celacouc Sicon
The silicone rubber cable is flexible and ozone resistant, with crown effect and flame. It has good insulating properties and is resistant to high and low temperatures (-60-200℃). Arc and corona resistance are very good, making wire and cable production safe and reliable.
Secondly, cold resistance, coupled with heat resistance can be said that the working temperature range of silicone rubber is very wide, with the same reason as above is also a large binding energy.
Furthermore, resistance to aging by ozone, heat, UV rays and the atmosphere is excellent.
Oil resistance, to solvents, to radiation and flames is also good, as well as resistance to mold. Furthermore, the product is odorless and non-toxic, and has no adverse effects on human health when used.
Disadvantages of Caoutchouc Sicon
But it also has disadvantages. Traction resistance, tear and abrasion resistance at room temperature is much lower than that of natural rubber and other synthetic rubbers. Poor resistance to acids and alkalis, high cost, poor transformation performance.
Vinyl silicone rubber, regardless of processing ability, physical and mechanical properties, resistance to high temperatures and permanent compression deformation of silicone rubber, is relatively good. There are more applications in the cable industry.
RESUMÉ
It is about rubber cable and plastic cable in all aspects of the difference, advantages and disadvantages. ZMS cable more than ten years in the industry, to bring customers better and more professional cables, artificial qualification strict verification, trustworthy.
