Plastics and Polymers

The handle of an umbrella is typically made of plastic due to its durability, lightweight nature, and cost-effectiveness. Plastic materials are able to withstand exposure to the elements, such as rain and sun, without deteriorating quickly. Additionally, plastic can be molded into various shapes and designs, providing ergonomic and comfortable grips for users.

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.

A linear polymer, where the monomer units are connected in a straight line, can be described as having one starting point and one ending point. Examples of linear polymers include polyethylene and polypropylene.

Plastic furniture is lighter, more affordable, and easier to maintain than wooden furniture. It is also more resistant to moisture and other environmental factors, making it a practical choice for outdoor or high-traffic areas. Additionally, plastic furniture can be molded into various designs and colors, offering more versatility in terms of style and aesthetic appeal.

Plastic furniture is gaining preference over wooden furniture because it is typically more cost-effective, lightweight, durable, and easy to clean. Plastic furniture is also less prone to damage from weather and insects compared to wooden furniture, making it a popular choice for outdoor use. Additionally, plastic furniture is available in a wide range of designs and colors, offering more versatility in terms of style and aesthetic appeal.
