All You Need To Know About PVC Cables

Cables insulated and covered by a thermoplastic, known as Polyvinyl Chloride (PVC) are widely used since the 1950s. They are quite versatile in nature as their physical and chemical properties are concerned. These are considered in a number of applications from fixed wiring to flexible installations.

Another interesting feature is that these are available in several colours and sizes and are also made up of different conductors, as per requirements for House Wires India. You need to consult the leading PVC Cables Manufacturers for your project and select the colour and size as per the requirement. Below are some more details you should consider before you finalise the PVC for your project.

PVC Cables
Benefits of PVCs
Since the 1950s PVCs have begun to replace the rubber insulated and sheathed cables in the domestic wiring of households due to the easy processing method and also the benefits of durability and flexibility. It is also cost-effective and has a service life of 25 to 30 years. The benefits can be summarized as below:

Even though PVCs are rigid and hard, they can be modified as per requirement with the help of plasticizers, stabilizers, lubricants and fillers which help in enhancing and modifying its physical and chemical properties. It is considered as one of the most versatile thermoplastic which is also easily recyclable!

The most important property that is looked for is that of being flame and shock retardant, especially when used in electric cables by Power Cable Manufacturers. As mentioned earlier that it can be modified with the help of plasticizers, stabilizers, lubricants and fillers, PVCs can be made resistant to a wide range of chemicals including oils, acids and alkalis, which make it durable and resistant to abrasion. The various additives if added can improve its temperature range, a great leap from about -40 to 105°C, and also provide the resistance to sunlight, reduced smoke emission and improved water resistance.

It’s physical and chemical properties make it suitable for applications where the cables are exposed to extreme high or low temperatures like use of arctic-grade PVC or where protection against UV light is required to avoid degradation. Insulated PVCs arewidely used owing to its good insulating properties and low corona resistance, which makes it suitable for low and medium voltage cables and low frequency insulation environment.

Types of PVCs
PVCs are known for their insulation properties and hence are compared with XLPEs, which means a fair comparison between a thermoplastic and a thermo set material. The thermo set versions of PVCs are cross-linked with electron beam technology and are expensive, which makes them suitable for applications in defense and automotive industries. Now, the most commonly used PVCs which are considered in the different industrial units can be summarized as below:

  • Twin & Earth cable (624Y) –Mains electricity wiring.
  • Tri-rated cable – These comply with the CSA and British Standards and are considered for switchgear and panel wires.
  • 2491X cable (H05V-K / H07V-K) –Panel wires.
  • 218Y cable (H03VV-F) – Domestic and commercial power supply.
  • 318A cable (Arctic grade) - Power, lighting and internal wiring cable, AC and DC telecommunications applications
Consult the leading PVC cables manufacturers now to get the best quality cables as per your requirement from the different types available in the market. Also, don’t forget to check if they comply with all the quality checks and standards.

What Are The Best Uses Of Sodium Citrate Dehydrate?

Sodium Citrate Dehydrate is sodium salt resulting from the chemical combination of citric acid with two molecules of water. The taste of the chemical compound, sodium citrate dihydrate is sour yet salty.

It has got a wide range of applications from being used as a food preservative or as a flavoring agent in foods and beverages, as pH controller in pharmaceuticals industry, as an alkalizing agent, a buffering agent, emulsifier and sequestering agent.

Even though preservatives are generally thought to be unsafe, the FDA Select Committee on Generally Recognized as Safe (GRAS) has identified citrate salts, including sodium citrate, as safe when used in usual quantities.

Now let us check the various applications of sodium citrate dihydrate, as mentioned below:

Sodium Citrate Dehydrate
Foods and Beverages Sodium citrate dehydrate is most commonly used in foods and beverages as preservatives. More specifically it is used as an emulsifier salt substance in processed food products like cheese. Also, this chemical compound is used as a flavouring substance, for example it adds to the flavour in various food and drinks, while the most common is that in soda.

The tart kind of flavour adds to the taste of the food in which it is used. The food products in which sodium citrate dihydrate is used are gelatin mix, ice-cream, jams, sweets, milk powder, processed cheeses, carbonated beverages, and wine. The other areas in the food industry utilising the benefits of sodium citrate dihydrate are as below:

  1. Dairy Confectionery
  2. Bakery products
  3. Sauces, Dressings and Seasoning
  4. Fruits and vegetables
  5. Meat and Seafood
  6. Cereals and snacks
  7. Dessert and ice cream
  8. Readymade and processed food
In beverages, sodium citrate dihydrate is used almost in every drink from alcoholic beverages to carbonated drinks of varying flavours, Instant Drinks, Syrups, Juices, energy drinks, tea and coffee, as well.

Pharmaceutical industry Sodium citrate dehydrate is used as a preservative which leads to improvement of stability of the chemical combination of the drug. It is also used as an anti-oxidant and blood anticoagulant. The applications in the pharma industry include Clinical Nutrition Medical Devices, OTC, Food Supplements and Oral Care Skin Care Soap and Bath Products.

Cosmetics Colour cosmetics, deodorants, hair care fragrances etc.

Cleaning and Detergent substances This includes both dish washing cleaning materials as well as laundry care and surface care products.


Industrial The citric acid component is generally used as a chemical polish and is also used in the treatment of aluminum, copper and other metal substances. Sodium citrate dehydrate is actually a versatile chemical component which is also an essential component in the desulphurisation of gas and oil recovery due to radioactive nuclear reactors.

  • Adhesives, Sealants
  • Agrochemicals and Fertilizers
  • Construction and Fine Chemicals
  • Inks and Paints
  • Coatings and Metal Surface Treatments
  • Oil Drilling, Ore Mining and Refining
  • Paper, Plastics and Polymers
  • Textile and Leather
If you are working with any of the above mentioned projects, sodium citrate dehydrate will be necessary. Just make sure that you consult the leading manufacturers of calcium citrate India and sodium citrate dehydrates for genuine products at the most reasonable price. Also check for the expiry dates as these are used in critical areas of food and beverages along with pharmaceuticals.
