What is Polypropylene?
Polypropylene is a plastic polymer with the chemical formula C3H6. It is used in many different settings, both in industry and in consumer goods, and it can be used both as a structural plastic and as a fiber. This plastic is often used for food containers, particularly those that need to be dishwasher safe.
The melting point of polypropylene is very high compared to many other plastics, at 320°F (160°C), which means that the hot water used when washing dishes will not cause dishware made from this plastic to warp. This contrasts with polyethylene, another popular plastic for containers, which has a much lower melting point. Polypropylene is also very easy to add dyes to, and it is often used as a fiber in carpeting that needs to be rugged and durable, such as that for use around swimming pools or on miniature golf courses. Unlike nylon, which is also often used as a fiber for rugged carpeting, it doesn't soak up water, making it ideal for uses where it will be constantly subject to moisture.
Research is ongoing with polypropylene, as makers experiment with different methods for synthesizing it. Some of these experiments yield the promise of exciting new types of plastic, with new consistencies and a different feel from the fairly rigid version that most people are used to. These new elastic versions are very rubbery, making them even more resistant to shattering and opening up many different uses for an already pervasive plastic.
Polypropylene is not as sturdy as polyethylene, but it has benefits that make it the better choice in some situations. One of these situations is creating hinges from a plastic, such as a plastic lid on a travel mug. Over time, plastics wear out from the repetitive stress of being opened and shut, and eventually will break. Polypropylene is very resistant to this sort of stress, and it is the plastic most often used for lids and caps that require a hinging mechanism.
Like many plastics, polypropylene has virtually endless uses, and its development has not slowed since its discovery. Whether used for industrial molds, rugged currency, car parts, or storage containers, it is one of a handful of materials the world is literally built around.
i want to know about polypropylene used in doormat segments
i wanted to know what material is added to plastic to change it to Polypropylene?
Would you use polypropylene to manufacture an electric hot water cylinder for domestic use?
This product is used to make TVT sling mesh to hold a prolapse uterus or hernia problems. I just had one removed from being in me for two years and the pain was just awful. I'm sensitive to antibiotics and had to take them to save my life because it was attacking my organs and my immune system, and I couldn't fight anything.
How do you explain using that for a medical device when they don't allow them in the dumps any longer? Also, if they continue using this, women will be in so much pain that men will have to become celibate as the pain is too excruciating to make love. Plastic doesn't belong in the human body. Now I feel wonderful since it's out and I am the lucky one. Now I have to clean my system with normal herbs and exercise. Don't get that mesh, folks, or you will be in deep trouble. Death was at my door twice this year.
The radiator core support in my 2006 Ford Freestyle was recently cracked. Is this part made of polyropylene? How can I find out and if it is what type of glue can be used to repair the crack?
The part is quite expensive and I cannot afford to replace it (I am on disability, a fixed income and 65 year old female and really need to get to my doctor ASAP) so I have been without transportation in a rural area. I would appreciate an answer soon if possible.
How is polypropylene recycled or disposed of safely?
Where do I find polypropylene cloth? Such as for trampolines?
Is this polypropylene used to make mesh to help women with proplased uterus or hernias in men. It is not mentioned here.
How is PP manufactured? With what materials/gases?
Plastics such as polypropylene and polyethylente can be made to biodegrade in landfills, if an additive is put into them at the time of manufacture. In landfills, it contributes to methane capture, which saves the equivalent to the fuel used in 14 million cars a year.
To the gentleman looking to "get back into the water":
My name is Luke. I work for my family business which is a company that designs and manufactures protective packaging. We also manufacture OEM and retail products. We work with many different types of foam materials and polymers.
I would be glad to lend my expertise and some time to help you out. You can reach me by looking up Barber Packaging Company. Please don't respond on here because I probably won't re-visit this forum.

As a 5 year old I remember my father getting third degree burns on his hand while boiling butter and then pouring it onto a plastic carrier which melt off and went directly onto his hands. Thanks now to Polypropylene cookery carriers, this problem has now been taken care of.
to all those wanting to glue Polypro- this is a very difficult to bond plastic. Your best option is to rough the surfaces (with sandpaper or sandblasting) corona treat the surface if you have access to a corona wand, and then use a two-part epoxy specially formulated for PP- 3m Scotchweld 8010 or 8005.

I see polypropylene used as a low tack adhesive sold in sheets and rolls for crafting projects. It adheres to many surfaces without leaving any residue or smearing, is repositionable, and can come in clear and glossy sheets. But is it safe for the skin? As a crafter I handle this material constantly, and I can't seem to find any information on the FDA or manufacturer's website about it either.

What is your feeling of baby bottles being made with this plastic polypropylene?
can i know the price of virgin polypropylene code named S100.F380. its very urgent.
I love the ocean so I moved to Fort Lauderdale. In 1989 I became a quadriplegic. However, nothing was going to stop me from swimming in the ocean.
One day, I gathered a couple of teenagers, and brought them to the beach with me along with a giant queen sized bed sheet. Then they lifted me from my wheelchair, and placed me on the bed sheet.
Three of them dragged me to the water on the sheet until I became fully buoyant. It worked great! Then I started thinking! What if I took a thin sheet of polypropylene, maybe 1/8 of an inch thick, and bent it up slightly in the front and sides to prevent sand from getting on me. Also, drilling two holes on the top where my head will go, and insert nylon anchor rope to use for pulling me into the ocean.
The polypropylene sled would reduce friction, and protect me from the sharp objects that might be hidden in the sand. It really would serve the same purpose as a stretcher used by EMS. I would also like to attach a 24 inch soft plastic rod holding a blue flag with the white ISA (International Symbol of Accessibility a/k/a Wheelchair Symbol) printed on it.
The reason for this, is to pull it up on shore after transferring me into the water, and indicate to the lifeguard it is not going to be used as a flotation device.
It would strictly be used as an ambulatory device to bring an injured party to and from the ocean from an umbrella that the rest of my family would be hanging out. Somebody please help me!
I don't care about patent rights, I just want to get back in the ocean again! I think polypropylene is the right material! Please advise!
Is is safe to use a polypropylene sediment filter in a reverse osmosis water filtering system? The other two filters in the system are carbon.
Plastics are completely unsustainable because they all come from oil. We have reached peak oil and we can no longer continue to utilize plastic as excessively as we currently are. We need to think before we purchase products made from plastic and consider whether it's truly worth it.
is polypropylene used in making toasters? what other plastics are used?
I think this article is fab and very informative.
PLA is made from plant resin, and is just as good if not better than those made from fossil fuels. Henry Ford had originally planned to use bio-plastics in his cars. PLA is biodegradable and can be composted.
As far as I know oil is used to make all plastics. Polypro is very safe, I don't understand how the one person can say plastics are crap, they make up so much of our world today. On the "plastics aren't green" issue what if your car didn't implement so much plastic, you would burn 50x more gas. People need to think before they speak. As for the UV resistance and the winter weather resistance polypro is pretty resistant to most things so I think you both would be good.
I would like to connect two polypropylene containers together, and am wondering if anyone knows of an epoxy or other glue that will hold them together permanently.
Thanks so much
During industrial processes Polypropylene is used as building blocks for a wide variety of polyurethane foam products. How is industrial wastewater treated for any contaminants this product may produce?
no mention of polypropylene gloves and socks which, I keep reading,are suitable for Antarctica but no idea given on where to obtain these !
I am doing a case study of bio-form bras which also use polypropylene and i was wondering if any one can tell me the environmental effect of using polypropylene in manufacturing.
I have been trying to research it but due to the fact that it is a reasonable new plastic, no one seems to want to list its faults!
I'm planning to purchase a swimming pool cover. Some are made using polypropylene and others use polyethylene. Which would be better to use in Michigan in the winter?
So it is plastic. Then how can those non-woven Polypropylene bags call themself "green"?
Is Dacron the same as polypropylene?
I need UV resistant rope for my flag pole and was told that Dacron fills the bill. Problem is all I can find in Dacron is fishing line. Flag pole companies sell nylon and polypropylene.
polypropylene is what people sniff and get effects.
If you are comparing a wool or polypropylene rug, you might like to consider that the polyprop is relatively inert as well as being durable, while the wool has probably been processed using highly toxic chemicals and may cause skin irritation.
Since it's a plastic, is oil used to make polypropylene?
If you are looking for a soft rug that is safe, I would suggest Wool. Other safe, natural choices would be a woven grass rug. Ultimately, all synthetics and plastics are crap, and are full of harmful chemicals.
Dose Polypropylene contain PVC or bisphenol-A. I am looking for a soft rug for the kids play room/ our office and need the plastic to be safe.
