What makes plastics strong




















Home About Contact Blog. Email: info creativemechanisms. Call Now: Here is our list of the top 11 plastics the modern world simply cannot do without: 1. Polyethylene PE : There are a number of different variants of polyethylene. It has high ductility but low tensile strength. HDPE: A stiff plastic used for more robust plastic packaging like laundry detergent containers as well as for construction applications or trash bins.

UHMW: Extremely strong plastic that can rival or even exceed steel in strength and is used is for applications like medical devices e. Polyvinyl Chloride PVC : Polyvinyl Chloride is perhaps most well known for its use in residential and commercial property construction applications.

Schedule 40 PVC pipe Three words or short phrases to describe the major benefits of PVC relative to other plastics and materials would be: Brittle Rigid although different PVC variants are actually designed to be very flexible Strong 4. Polypropylene PP : Polypropylene is used in a variety of applications to include packaging for consumer products, plastic parts for the automotive industry, special devices like living hinges , and textiles.

Styrofoam peanuts One short phrase to describe the major benefits of Polystyrene relative to other plastics and materials would be: Foam Applications 6. Polylactic Acid PLA : Polylactic Acid is unique in relation to the other plastics on this list in that it is derived from biomass rather than petroleum. Polycarbonate PC : Polycarbonate is a transparent material known for its particularly high impact strength relative to other plastics.

A polycarbonate greenhouse Two words or short phrases to describe the major benefits of Polycarbonate relative to other plastics and materials would be: Transparent High Strength 8. A laser being directed through an acrylic lens Two words or short phrases to describe the major benefits of Acrylic relative to other plastics and materials would be: Transparent Scratch Resistant 9.

Acetal Polyoxymethylene, POM : Acetal is a very high tensile strength plastic with significant creep resistant properties that bridge the material properties gap between most plastics and metals. Surplus atmospheric oxygen and high temperatures are required to ensure effective controlling of the combustion process.

However, if there is not enough oxygen and the temperature is too low, the plastic cokes into black carbon and other hazardous products. They do not burn on their own or burn poorly, but produce fluorine or chlorine compounds in heat in the presence of burnable substances and can even emit chlorine gas. Special procedures are required here during which the products must be further transformed or bonded. The simplest and most cost-effective way of stemming the flow of refuse into the oceans is obvious — restrict consumption and increase the recycling rate.

Plastic which is not disposed of in the environment in the first place does not have to be laboriously broken down or collected later. Explore further. More from Chemistry.

Simply combining a large volume of clay, nanosize platelets into one continuous block, however, results in a brittle chalklike material riddled with cracks.

Researchers created a strip of clear material as thick as a sheet of plastic wrap by using a robotic arm to uniformly blend many millions of square clay platelets nanometers on each side and one nanometer thick one nanometer equals 3. The robo-arm crafted this new material by dipping a piece of glass about the size of a stick of gum alternately into the gluelike polymer solution and then into a liquid that was a dispersion of clay nanosheets. The end result—consisting of layers of the blended nanomaterials and polymer—was modeled after mother-of-pearl found in the lining of mussel and oyster shells.

The bricks-and-mortar structure allowed the layers to form cooperative hydrogen bonds, which gives rise to what Kotov called "the Velcro effect"—one of the reasons the material is so strong.

Such bonds, if broken, can reform easily in a new place. Kotov is developing methods to apply the composite in the development of microelectromechanical systems MEMS and devices, as well as microfluidics devices for actuation and valve manufacturing.

In addition to military uses, improving the ductility of the researchers' nanoinfused plastics could aid in the development of dent and scratch-resistant cars and windshields. Now that the researchers have created a composite exhibiting resistance to deformation stiffness and resistance to load strength , they are working to improve the composite's ability to dissipate energy, thus improving its toughness, says U.

Now a Tel Aviv University researcher is giving the quest for environmentally friendly plastics an entirely new dimension — by making them tougher than ever before. Moshe Kol of TAU's School of Chemistry is developing a super-strength polypropylene — one of the world's most commonly used plastics — that has the potential to replace steel and other materials used in everyday products.

This could have a long-term impact on many industries, including car manufacturing, in which plastic parts could replace metallic car parts. Durable plastics consume less energy during the production process, explains Prof. And there are additional benefits as well. If polypropylene car parts replaced traditional steel, cars would be lighter overall and consume less fuel, for example. And because the material is cheap, plastic could provide a much more affordable manufacturing alternative.

Although a promising field of research, biodegradable plastics have not yet been able to mimic the durability and resilience of common, non-biodegradable plastics like polypropylene. Kol believes that the answer could lie in the catalysts, the chemicals that enable their production. Plastics consist of very long chains called polymers, made of simple building blocks assembled in a repeating pattern. Polymerization catalysts are responsible for connecting these building blocks and create a polymer chain.
