Polyvinyl Chloride or better known as PVC among the masses is a breakthrough material in the plastic segment with a wide range of usage possibilities in the construction, transportation, electronics, packing and healthcare industries. PVC wire is considered to be the best for use keeping in mind the durability and effectiveness of the material.
If we compare it with other thermoplastics then the method to prepare PVC is significantly different, it uses two primary materials namely common salt and hydrocarbon feedstocks. While the former comprises of 53% composition in molecular weight the later uses 43% in the mix.
PVC has the following physical properties to its advantage:
High Tensile Strength
It has a tensile strength of 2.60 Nmm² that makes it a perfect material to be integrated in the wiring industry.
PVC has an unmatched notched impact strength of 2.0 – 45 Kj/m² making it a preferred choice for various applications.
Coefficient of Thermal Expansion
No material can stand strong the in the wiring industry without a good thermal coefficient in terms of expansion, in this case being 80 x 10-6
Apart from the above mentioned physical attribute PVC has a high max cont use temp of 60 degrees with an impressive density of 1.38 g/cm3. However, the positive qualities do not end here. On a scale of 1-4 where 1 being poor and 4 being very good PVC has the following implications in chemical resistance.
Dilute Acids– Score of 4- Verdict: Very Good
Dilute Alkalis– Score of 4- Verdict: Very Good
Greases and Oils– Score of 3- Verdict: Good
Alcohols– Score of 3- Verdict: Good
When talking about hydrocarbons PVC has very resistance to aliphatic hydrocarbons while it works fairly for aromatic and halogenated hydrocarbons. Hence, due to its unmatched physical and chemical attributes PVC is considered as one of the best materials to be used in the wiring industry and it is advisable to use it in any new projects or while replacement in the old ones.
