Polypropylene Vs. Nylon: Material Differences And Comparison

1.Polypropylene and Nylon

Polypropylene and nylon are both thermoplastics that are used to manufacture products for industrial and household applications. Though nylon and polypropylene share similar traits, they are very different. To start, nylon is a condensation polymer, whereas polypropylene is an additional polymer. Nylon is produced by reacting a diamine with a dicarboxylic acid.

These materials also differ in their uses. The properties that make each one unique mean they fit into separate application categories. For example, nylon can be used in place of aluminum engine parts or to insulate electrical lines. Polypropylene, by contrast, gets built into semiconductor components and auto batteries due to its resistance to water and solvents.

Nylon's malleability makes it a useful material for design prototyping. It is the perfect low-friction material for many items, including rollers, seals, and wheels that must tolerate resistance. On the other hand, polypropylene is ideal for moving components like hinges and gears because it can bend under load without cracking but is still less flexible than nylon.

 

2. What is Polypropylene?

Polypropylene, also known as PP or polypropene, is a polyolefin or saturated polymer. It is a low-density thermoplastic with good resistance to heat. Other characteristics of PP include: chemical resistance, elasticity, toughness, fatigue resistance, and electrical insulation capability. The dual functionality of polypropylene as both a plastic and a fiber is another invaluable

 

3. What Is Nylon?

Nylon is the commercial name for a particular synthetic polyamide thermoplastic. It is created through a reaction between a diamine and a dicarboxylic acid. A molecule with carboxylic groups reacts with a molecule with amine groups at both ends to create polyamide-like nylon. One of nylon's key purposes early on was to replace silk. It can be shiny, semi-shiny, or dull. It is also capable of experiencing significant elongation. Nylon resists abrasion, numerous chemicals, insects, and fungi. It has good thermal and fatigue resistance and is highly machinable. Additionally, it is also a very effective noise dampener.

 

4. Polypropylene vs. Nylon: Applications and Uses

Since nylon is a good insulator, it is frequently used to replace aluminum in engine parts and to insulate electrical cables. The water- and solvent-repelling properties of polypropylene, meanwhile, make it a popular material for semiconductor components and automotive batteries. Polypropylene is utilized in laboratory settings and in chemical tanks and plating because of its durability and resilience in the face of stress.

Nylon is a great material for design prototyping because of its malleability, which allows for reheating and re-molding. And with its low friction coefficients, nylon is ideal for numerous parts like rollers, seals, and wheels.

Although less flexible than nylon, polypropylene can bend under stress without cracking, which makes it a perfect material for moving parts like hinges and gears.

 

Both polypropylene and nylon parts can be manufactured via injection molding. It may be simpler to use polypropylene in injection molds because the raw material pellets have a lower melt viscosity than nylon pellets. Nylon - especially Nylon 12 - is a useful material for both injection molding and additive manufacturing because of its strong heat resistance.

Finally, it's important to note that FDA-compliant grades of nylon and polypropylene are both readily available. Therefore, both materials are common in the food and beverage industry and the medical sector.

 

5. Polypropylene vs. Nylon: Cost

Both nylon and polypropylene are considered inexpensive materials. However, polypropylene is significantly cheaper than nylon. The global average price for polypropylene is roughly $1.3 per kilogram, whereas nylon goes for approximately $2.4 per kilogram.
