What Is The Difference Between Polypropylene And Pvc?
Polyvinyl Chloride (PVC) and Polypropylene(PP) are two common types of thermoplastic meaning they can be melted and moulded in different shapes. As they both are plastics, both of them are synthesized from petroleum.
Polestar Polymers are India's leading polymer manufacturer. We manufacture both PVC and PP (PolyPropylene), customized according to your needs. Suppose you are looking for high-quality PVC or PP components. In that case, you can connect with our expert team of premium PVC sheet and PP sheet manufacturers to select the right product according to your application.
Being experts in polymers, in this blog, we will explain to you the properties of both these plastics and discuss the differences between these two materials so that you can pick the best for your application.
What is Polyvinyl chloride (PVC):
PVC is one of the most commonly used plastic products. High-quality PVC plastic can obtain varied properties by adding additives according to the purpose. It was first synthesized in 1872. PVCpolymer comes in two distinct forms: Rigid and flexible.
The significant difference between the two is in its tensile strength. PVC plastic is often used in industrial applications for wires, pipes, rods, rollers, pulleys and as other machine components in varied applications.
What is Polypropylene (PP):
Polypropylene (PP) was first synthesized in 1951. Its excellent chemical resistance, elasticity, toughness and lightweight nature make it a great plastic product. All of these properties make it an attractive plastic to be used in machine components and wires. Moreover, PP is 100% recyclable, making it a preferred choice by environmentally conscious companies.
Polypropylene (PP) vs PolyVinyl Chloride (PVC):
PP and PVC have different benefits depending on the industrial application. Though in some cases, they can also be used interchangeably.
Here are some significant differences between the Polypropylene and PolyVinyl Chloride:
| Property | Polypropylene (PP) | Polyvinyl Chloride (PVC) |
|---|---|---|
| Chemical composition | Carbon and hydrogen | Carbon, hydrogen, and chlorine |
| Melting point | 165-1750C | 140-1700C |
| Boiling point | 3510C | 4100C |
| Density | 0.90 g/cm3 | 1.40 g/cm3 |
| Impact strength | High | Low |
| Chemical resistance | Good | Good to fair |
| Heat resistance | Good | Fair |
| Chemical resistance | Good | Good to fair |
| Electrical properties | Good | Good |
| Recyclability | 100% recyclable | 80-90% recyclable |
| Cost | Low | Low to medium |
The best material for a particular application will depend on the specific requirements. Here are some additional things to consider when choosing between polypropylene and PVC:
-
Health and safety:
PVC components can contain harmful additives, so choosing products made with food-grade PVC or PVCcertified as safe for use in children's products is essential.
Environmental impact:
Both polypropylene and PVC are made from non-renewable resources, but polypropylene is generally considered to be more environmentally friendly because it is easier to recycle.
Cost:
Polypropylene is typically more expensive than PVC, but the longer lifespan of polypropylene products may offset the cost difference.
Applications in which PP and PVC can be used interchangeably:
-
Electrical wires insulation
Textiles
Medical packaging and containers
Ultimately, the best way to choose between polypropylene and PVCis to consider your application's specific requirements and the factors most important to you.

FAQ's
1. Is PP made from PVC?
No, PP is not made from PVC. There are both different types of polymers. PP is made from hydrogen and carbon.
2. What is better PVC or PP?
PVCand PP both have distinct characteristics. So according to the kind of application, the choice of polymer will vary. There are specific applications such as food and beverage packaging, automotive components or consumer products where PP is favoured over PPC. Plumbing industries prefer PVC.
3. Is PVC material long-lasting?
Yes, PVC is highly durable and long-lasting plastic. Weatherproof and moisture resistant, it can last long, even under tough conditions.
4. Is Polypropylene polymer waterproof?
Polypropylene is resistant to water absorption. This property makes it a preferred polymer for the packaging industry.
5. Is PP acid-free?
Polypropylene (PP) is an acid-free polymer. This polymer is also highly resistant to chemicals and solvents.
