About Polypropylene (PP) plastic

Polypropylene (PP) plastic is a thermoplastic polymer developed for commercial application in 1957. It is also known as polypropene and includes Homopolymer and copolymer grades.

As a popular engineering plastic, Polypropylene (PP) offers excellent chemical resistance to acids, alkalis, and solvents. It is also easily welded and machined. Therefore, polypropylene (PP) plastic is frequently used to lining structural tanks, plating barrels, orthotic and prosthetic devices, and pump and valve components. In addition, polypropylene (PP) plastic is commonly used in semiconductor and chemical industries due to its superior durability in corrosive environments.

Polypropylene (PP) doesn’t absorb moisture. It is stranger than High-Density Polyethylene (HDPE) and offers good abrasion resistance, moisture resistance, and formability. Homopolymer polypropylene (PP) plastic works well between -4°F (-20°C) to 212°F (100°C) and can be thermoformed into different shapes. Therefore, polypropylene (PP) plastic is found in medical, automotive, packaging, and consumer products.

Frequently Asked Questions about Polypropylene (PP) plastic

Yes, UVTECO can provide injected polypropylene parts. Contact us for more information.

Yes, polypropylene plastic is waterproof because the polypropylene molecules are close together. This closeness doesn’t allow water to pass through this plastic. As a result, it becomes moisture- and waterproof. Only 0.01% of water is absorbed by polypropylene.

No, polypropylene plastic is not biodegradable by nature. Because it’s made of synthetic material. So the microorganisms can’t break it down.

However, it can be decomposed over a long time, up to hundreds of years. Since it doesn’t break down quickly, it can be recycled.

Polypropylene is widely used in different industries because of its strength and adaptability. It is frequently used in manufacturing consumer products, sports, fashion, rigid and flexible packaging, and healthcare sectors.

Because of its strength and resistance to chemicals, it is also widely used to produce car parts like bumpers and panels.

Yes, you can laser-cut polypropylene. We suggest using a CO2 laser, fiber laser cutting isn’t suitable. Please note that laser cutting requires precision and highly advanced technology. So, we discourage DIY polypropylene laser-cutting without proper knowledge and instruments.

No, polypropylene is not PVC plastic. Although they are both thermoplastic, they differ in a few ways. Polypropylene’s main components are carbon and hydrogen. However, PVC includes the hazardous material chlorine.

If burned, PVC releases harmful byproducts such as dioxins, hydrochloric acid, and chlorocarbons. Polypropylene, on the other hand, releases carbon dioxide and water.

Yes, polypropylene is flammable. Its core elements, hydrogen and carbon, make it flammable. Polypropylene’s flash point is 260 °C, and its autoignition temperature is 388 °C.

No, polypropylene doesn’t rust because it isn’t a metal. Rust occurs when metals oxidize in the presence of moisture. Polypropylene is a plastic material that is resistant to both corrosion and chemicals. This resistance makes it perfect for various applications where exposure to moisture or chemicals might otherwise cause damage.

Polypropylene is not extremely UV-resistant in its base form, so consistent exposure to sunlight can degrade its integrity.

However, adding additives like titanium oxide or carbon black pigments can improve polypropylene’s UV resistance. You can also add absorbers, like Benzotriazoles, to improve the UV resistance of polypropylene by only 0.5%.

Yes, polypropylene plastic is generally safe to use with hot water and is FDA-approved for making food storage boxes.

Polypropylene has high heat tolerance. And still, it doesn’t leak any hazardous chemicals when burnt.

Polypropylene plastic is a better chemical-resistant, lower-density thermoplastic than PVC and PE plastic. It also has better dimensional stability.

Polypropylene is durable, flexible, lightweight, moisture-resistant, and affordable. All these characteristics make it popular in the plastic product manufacturing industry.

Polypropylene plastic has numerous advantages:

  • It can withstand harsh environments without deforming.
  • This plastic is waterproof. So it is less likely to deteriorate and mold.
  • Polypropylene is the most effective plastic.
  • PP is recyclable.
  • It is non-toxic and safe for food storage.
  • Lightweight and easy to transport.
  • It is chemical-resistant and isn’t made of toxic elements, which is safe for the environment.

Polypropylene is strong enough and can withstand harsh environments without breaking. The pressure PP can tolerate is around 4800 psi. So, despite being lightweight, PP can withstand fairly heavy loads.

Yes, polypropylene lasts long.

You can expect a lifetime lasting of PP. If polypropylene products aren’t exposed to sunlight, they can last up to 200 years. However, most consumer products will stay usable for 20 to 30 years.

Polypropylene has a good heat resistance characteristic. Its functional temperature ranges from 130°C to 171°C (melting point). The melting point should not be confused with the flash point.

Melting point refers to when a substance starts to melt. Flashpoint refers to the minimum temperature when the substance begins to release vapor.

Yes, you can autoclave polypropylene.

You need to implement the autoclave cycle for PP at 121 °C and 15 PSI. The recommended cycle period is 20 minutes. Remember to ensure proper air circulation during the autoclave process, particularly when venting and cooling.
