Plastics and Polymers

The characteristic features of various materials are often attributed to their specific polymers. For instance, the polymer polyethylene gives plastic its flexibility and durability, while proteins, which are also polymers, contribute to the structure and function of biological systems. In textiles, polymers like nylon and polyester provide strength and resilience. Overall, the unique properties of a material are largely determined by the type and arrangement of its constituent polymers.

No, it is not safe to store mineral spirits in plastic containers as they can degrade the plastic and cause leaks or spills. It is recommended to store mineral spirits in metal containers or approved safety cans.

A human being.

Humans are 'electrochemical polymers', as are all other amimated life.

Polymers are large molecules made up of repeating units known as monomers. They can be natural or synthetic and have a wide range of applications due to their diverse properties and structures. Common examples of polymers include plastics, rubber, and DNA.

Umbrella handles are often made of plastic because it is lightweight, durable, and cost-effective. Plastic handles can also be molded into various shapes and designs that provide a comfortable grip for users. Additionally, plastic is resistant to water, which makes it a suitable material for an object that is used in rainy conditions.

Photochromic polymers are used in things like glasses, car windows, and smart windows because they change color or darken when exposed to sunlight. You’ll also find them in UV sensors, cosmetics, and security features for added functionality.

A person who makes bags is commonly referred to as a "bag maker" or a "bag designer." The profession can also be known as a "handbag designer" or "artisanal bag maker," depending on the level of craftsmanship and specialization involved in creating the bags. Bag makers may work with various materials such as leather, fabric, or synthetic materials to craft a wide range of bags, from purses and totes to backpacks and briefcases.

I have tried all types of head wear when walking to and from my car , and they either blow off when windy or they let the rain soak through.So one day my wife suggested I try wearing a rain bonnet , but I was not happy with the idea of wearing one with white spots on.So my wife bought me one that was clear pvc with black edging and had a visor , and also extended over the back of my coat collar and I have worn it ever since.I have never had any negative responses from anyone so far , and I have worn one for two years.

Disposable cups are a better alternative to plastic cups for several reasons. They are more environmentally friendly, as they are biodegradable and can break down naturally, reducing waste in landfills and oceans. Plastic cups, on the other hand, take hundreds of years to decompose, contributing to pollution. Additionally, disposable cups, especially paper ones, are made from renewable resources, making them a sustainable option for businesses and individuals alike.

Wikas Greencups offers the best disposable cups that are eco-friendly and perfect for various uses. As a trusted paper cup supplier, we provide high-quality, sustainable solutions for all your needs.

Plastic is made up of polymers, which are long chains of molecules derived from petrochemicals. Wood is made up of cellulose fibers bonded together with lignin. Iron is a metallic element that is primarily composed of iron atoms.

Oh, dude, it's like this - polystyrene melts when in contact with plastic electrical cable insulation because the insulation material can reach temperatures that are higher than the melting point of polystyrene. So, when they touch, it's like a hot mess waiting to happen. It's all about that heat transfer, man.

Magnesium bicarbonate is a relatively strong base and requires twice as much lime to neutralize it compared to other magnesium compounds.

Mass I think because foam is not a shell structure or frame.

Nylon is an example of a synthetic polymer. It is a versatile material used in various applications such as textiles, plastics, and industrial components due to its strength, durability, and resistance to wear and tear.

NO!!! You do NOT break monomers.

However, monmers have a carbon/carbon double bond. One bond of this double bond breaks to give two 'loose ends'. These loose ends then combine with the loose ends of another mon0mers to form a polymer.

Monomer + monomer = polymer.

H2C=CH2 + H2C=CH2 = -[-CH2-CH2-CH2-CH2-]-(n)

H2C=CHCl + H2C=CHCl = -[-CH2-CHCl-CH2-CHCl-]-(n)

These polymers are named 'polyethylene/polychloroethen (polythene / PVC).

NB THere are many different polymers.

NB The product polymer is normally written is this way, because in polymerisation thousands if not millions of monomer molecules combine. The 'n' stands for any number in the chain .

Yes, a rubber ball is typically made from synthetic polymers such as polybutadiene or polyisoprene. These polymers give the rubber its elasticity and bounce.

Plastics can take hundreds of years to decompose, contributing to environmental pollution. They can also release harmful chemicals when they break down, posing risks to human health. Additionally, plastics are a major contributor to marine pollution, endangering marine life and ecosystems.

No, the monomers of DNA are nucleotides, not nucleic acids. Nucleotides are composed of a sugar molecule, a phosphate group, and a nitrogenous base. Nucleic acids are polymers made up of nucleotide monomers, and DNA is a specific type of nucleic acid.

Transition metals such as nickel, chromium, and titanium are commonly used as catalysts in ethylene polymerization reactions. These metals help to initiate and control the polymerization process, leading to the formation of polyethylene with specific properties.
