Plastics and Polymers

Bio-plastics were not discovered by one individual; they were developed through research and innovation by scientists and engineers over time. However, the concept of bio-based materials has been around for centuries, with a more recent emphasis on creating sustainable alternatives to traditional plastics.

Yes, acetone can be used to thin oil-based paints and clean painting tools. However, it is not recommended for thinning latex or acrylic paints as it can cause them to break down and lose their properties. It's important to use acetone in a well-ventilated area and follow safety precautions when working with it.

To remove the plastic from Kachooz pencil toppers, simply tear or cut it along the perforated edges to expose the pencil topper inside. Be careful not to damage the pencil topper while removing the plastic.

Yes, you can use a paper clip as a substitute for eye pins when creating polymer clay items. Simply straighten out the paperclip and insert it into your clay creation before baking. Just ensure the paper clip is fully covered by the clay to securely hold it in place.

Yang Yoseob, a former member of the K-pop group Beast (now known as Highlight), has not publicly confirmed any plastic surgery procedures. Any rumors or speculations about his appearance are subjective and should be taken with caution. It's important to respect his privacy and focus on his music and talent.

For one, dextrose and glucose are both monomers, or to be specific, monosaccharides.

Dextrose and glucose are essentially the same thing, except that dextrose is specifically D-glucose. There exists two stereoisomeric forms of glucose, being D-glucose and L-glucose. "D" refers to "right" and "L" refers to "left". Essentially stereoisomeric means that D-glucose and L-glucose are mirror images of each other. T

The difference between L-glucose and R-glucose is that L-glucose cannot be metabolized during glycolysis which is a component of cellular respiration.

No, not all vinyl contains phthalates. Phthalates are used as plasticizers in some vinyl products to make them flexible, but there are phthalate-free alternatives available. It's important to check product labels or contact manufacturers to determine if phthalates are present.

The plastic in aspirin bottles is typically made of high-density polyethylene (HDPE) or polypropylene (PP) to provide a tight and moisture-resistant seal to protect the medication inside from environmental factors.

In polymerization, a water molecule is often eliminated as a byproduct in a condensation reaction between monomers. This process is known as dehydration synthesis. In the breakdown of a polymer via hydrolysis, water molecules are used to break the covalent bonds between monomers, resulting in the degradation of the polymer into its constituent monomer units.

Plastic shoes can be uncomfortable because they do not breathe well, leading to sweaty feet and potential odor issues. They are also not as durable as other materials, and can be prone to cracking or breaking easily. Additionally, plastic shoes are not environmentally friendly, as they are not biodegradable and contribute to plastic pollution.

Like lithium ion batteries, they do not suffer from battery memory but are also effected by gradual capacity loss caused by oxidization. It happens over a span of years from the manufacturing date, and lithium polymers (lipos) are basically lithium ion batteries that are easier to mold into various shapes needed for certain applications.

A vacuum mold is a shape that is placed in a vacuum molding machine to produce the finished piece. A hot plastic sheet is lowered onto the mold, and then air is vacuumed out from underneath. This pulls the soft plastic sheet down over the mold, and the plastic takes the shape of that mold. Cold air is blown over the setup for a short time, and the molded plastic sheet, with its molded shape formed in it, is lifted off the mold and sent on for further work.

In "Mean Girls 2," the plastics are Mandi Weatherly, Chastity Meyer, and Hope Plotkin. They are the popular girls in school who control the social scene and often engage in mean and exclusive behavior.

As with much household waste, plastic plates degrade very slowly due to the large hydrocarbon chains that are very difficult to break down. They take Millions of years to degarade releasing harmful gases into the atmosphere!

Most polymers are non-Newtonian fluids, meaning that their viscosity changes under different shear conditions. However, some polymers can exhibit Newtonian behavior under certain conditions.

Michael Jackson has undergone several plastic surgeries throughout his life, including multiple nose surgeries, skin treatments, and chin reshaping. The exact number of surgeries is not confirmed, but it is estimated that he had around 10 to 12 procedures.

The chemical formula for PVC (polyvinylchloride) is [-CH2-CHCl-]n, where n is equal to ~60,000 to 140,000. Actual useful formulations of PVC also include a small percentage of various stabilizers to enhance the performance and prevent discoloration from light and heat.

You could probably get one anywhere, but mainly during the summer.

Places like Walmart, Kmart, and Target should have them

The plastic bulge in some USB cables is typically a ferrite bead, which is a small cylinder of magnetic material designed to reduce electromagnetic interference and improve the cable's performance. It helps to filter out noise and signals that could disrupt the data transmission through the cable.

Yes, Captain Morgan rum is available in plastic bottles for sale in some regions. These plastic bottles are usually smaller in size and are convenient for travel or outdoor events.

Not all polymers are biodegradable. Biodegradable polymers are designed to break down into natural compounds when exposed to specific conditions, such as heat, moisture, or microbes. However, many conventional polymers, like plastics, are not biodegradable and can persist in the environment for a long time.

PVC polymers can become degraded through exposure to heat, UV radiation, or chemical agents. These factors can break down the polymer chains, leading to decreased mechanical strength, discoloration, and eventually structural failure. In the case of PVC, degradation can also release toxic byproducts such as hydrogen chloride gas.

To prepare a fantastic speech arguing that plastic bags should not be manufactured, you can start by researching and gathering strong evidence to support your position. Structure your speech with a clear introduction, body presenting key arguments, and a compelling conclusion. Utilize persuasive language, statistics, and real-life examples to engage your audience and drive your point home. Practice delivering your speech with confidence and passion to leave a lasting impact on your listeners.

The specific gravity of a polymer can vary widely depending on its specific composition and structure. In general, the specific gravity of most common polymers typically ranges from 0.9 to 1.4. It is important to consult specific material data sheets or conduct tests to determine the exact specific gravity of a particular polymer.

When a balloon is rubbed with plastic, electrons transfer from the balloon to the plastic, leaving the balloon with a net positive charge and the plastic with a net negative charge. This is known as triboelectric charging or static electricity.
