Plastics and Polymers

I really don't care if he did plastic surgery or not because i'm cassiopeia. but i just say he ever did surgery >,< ... such as jaw

you can compare on bottom ear...his jaw is changed.

you must find Sm young trainee video.. you will find the truth

he done alot surgery you can find it in google

polyethene is the 1st and then the third =2.45

i 6658 (poly)hydron b2 1

Poly(methane)

Poly(pentane(

This is all a load of rubbish dont believe it

A monomer with a carbon-carbon double bond (alkene) is most likely to form an addition polymer. The double bond can be broken to allow the monomers to add together without the formation of any byproducts.

Nylon is a synthetic polymer that is commonly used to make fibers that are durable and have high tensile strength, making them resistant to wear and tear. This makes nylon fiber a popular choice for items like clothing, carpets, and ropes that require strength and durability.

Polyethylene is a polymer that exists in both synthetic forms, widely used in plastic manufacturing, and natural forms, found in plants and trees as a waxy coating.

Polytetrafluoroethylene (PTFE), also known as Teflon, is a highly resistant plastic that can effectively contain extremely corrosive materials due to its chemical inertness and high chemical resistance. PTFE is commonly used in applications involving strong acids, bases, and other highly corrosive substances.

Polyethylene terephthalate (PET) is a synthetic polymer that becomes harder as the number of carbon atoms in the polymer chain increases, due to enhanced molecular packing and increased intermolecular forces. This property makes PET a suitable material for applications requiring stiff and rigid structures, such as in the production of plastic bottles and fibers.

On average, a person uses about 220 pounds of plastic each year. This includes plastic used in packaging, bottles, bags, utensils, and other items. The amount of plastic used can vary depending on individual consumption habits and geographic location.

yes you can in certain stores

just have a look around

A high impact polymer is a type of material that can withstand sudden and severe forces without breaking or shattering. These polymers are engineered to have increased toughness and durability, making them suitable for applications where impact resistance is important, such as in automotive parts, protective gear, or packaging materials.

A lattice is a regular arrangement of points or nodes connected by lines or edges while a polymer is a large molecule composed of repeating structural units called monomers. In a lattice, the arrangement is fixed and rigid, whereas in a polymer, the structure is flexible and can vary in composition.

One example of a synthetic polymer that is made into fibers that do not wear out easily is polyethylene terephthalate (PET). PET fibers are known for their durability, strength, and resilience, which make them suitable for applications requiring long-term wear resistance, such as in textiles for clothing and carpets.

If you are talking about 45 rpm records, 'singles', the plastic insert was called an adapter, or a spindle adapter. They allowed you to play 45's without the awkward 45 spindle you would otherwise have to insert.

Wooden or plastic handles are used on appliances like electric irons for safety reasons. These materials are non-conductive and help prevent electric shocks to the user. They also provide insulation from the heat generated by the appliance, making it more comfortable to hold during use.

Yes, plastic surfaces can be written on with permanent markers or special markers designed for writing on plastic. It is important to make sure the marker is dry before touching the surface to avoid smudging.

The truth is that in Korea plastic surgery is not such a big deal. I red that it's usual for young girls to receive on their 18th anniversary plastic surgery as a gift. There are some artist which have done plastic surgery, like Lee Minho, a Korean actor, or Tiffany from SNSD and Park Bom from 2ne1. But there are also idols which haven't done this, like BB's members, or Bi Rain. It depends on the idol if he has done or not plastic surgery. You can't put all of them in the same category.

Nylon 6,6 polymer forms at the interface of two liquid phases because the two reactants required for its formation are present at the interface, promoting polymerization. The reactants are sebacoyl chloride and hexamethylene diamine, which react to form nylon 6,6 polymer at the liquid-liquid interface due to the localized high concentration of reactants.

1. Polystyrene is highly inflammable and releases toxic fumes when burned.
2. Bakelite does not readily catch fire but can burn when exposed to high temperatures.
3. Polythene is a thermoplastic that is highly flammable and can melt when subjected to heat, releasing hazardous fumes.

It has been rumored that Minwoo from Boyfriend underwent plastic surgery, especially for his nose. However, he has not confirmed these rumors and it's important to remember that personal decisions regarding cosmetic procedures are private and should be respected.

To preface this Q&A, different plastics and plastic thickness have different decomposition times. For example, plastic foam will never decompose.

I have seen some websites say it takes 10-12 years to decompose (which is hard to believe), another say 450-800 years, and yet another say 1000 years. Apparently, there is some debate about the definition of "decomposed": Plastic never fully decomposes. Over time it goes through a process of photo degradation and breaks down into smaller and smaller pieces.

The different stock forms of plastics include pellets, sheets, rods, and tubes. Pellets are small beads of plastic used in injection molding. Sheets are flat pieces of plastic that can be cut to size for various applications. Rods and tubes are cylindrical forms of plastic used in machining and fabrication processes.

Small molecules used in making synthetic polymers are typically sourced from petrochemicals, such as ethylene and propylene, which are derived from crude oil or natural gas. These small molecules undergo polymerization reactions to form long chains of repeating units, creating synthetic polymers like polyethylene and polypropylene.

Cooking rice with plastic bags over the top and under the lid can be unsafe as the plastic may release harmful chemicals when exposed to heat. It's best to avoid using plastic bags in direct contact with heat when cooking food. Opt for using a proper lid to cover the rice while cooking instead.

Plastic icing is a type of sugar paste that is used in cake decorating to create intricate designs and decorations. It is made from icing sugar, gelatin, and glucose syrup, giving it a pliable texture that can be easily molded and shaped. It is often used to create 3D figures, flowers, and other decorative elements on cakes.

Singapore recycles about 4% of its plastic bags, with the majority still ending up in landfills or incinerated. Efforts to reduce plastic bag usage and increase recycling are ongoing to improve the situation.
