Plastics and Polymers

I think so but I'm not very sure my freinds at school eat some and they came to school perfectly heathy I think

They are wrapped to increase shelf life of the cucumber as respiration of the fruit through its' thin skin will cause it to deteriorate and go soft. The wrap also protects the fruit from damage but that is a secondary benefit.

Well that is a vague question that really depends on what kind of cloth you are referring to, what kind of plastic bag and what you define as a bunch.

Carbon fiber reinforced plastic and carbon fiber reinforced polymer refer to the same material, which is a composite made of carbon fiber and a polymer matrix. The terms are often used interchangeably, with the most common polymer matrix being epoxy resin. Both materials offer high strength-to-weight ratios and are used in a variety of applications such as aerospace, automotive, and sports equipment.

Menu dispensers are commonly made out of materials such as acrylic, wood, metal, or plastic. The choice of material depends on factors like durability, aesthetic appeal, and budget.

The concave plastic discs on the sidelines of football games are called pylons. They are used to mark the corners of the end zone to assist referees and players in determining the boundaries of the field. Players must cross the goal line inside these pylons to score a touchdown.

Yes, myofibrils are made up of repeating units called sarcomeres, which contain protein polymers called actin and myosin. These filaments slide past each other during muscle contraction, allowing for muscle movement. The arrangement of these proteins within the myofibrils gives muscles their striated appearance.

Plastic is either a) thrown out and buried in a landfill or b) recycled by sorting based on resin identification code which is a method of categorizing polymer types then broken down by a variety of methods such as heat compression.

No, carbon is the element that forms the backbone of most polymers. Oxygen may be present in polymer structures as well, but it is the carbon atoms that primarily link together to form the long chains characteristic of polymers.

Fiberglass is commonly used for making glass-reinforced plastic (GRP) due to its strength, durability, and versatility. Fiberglass is composed of fine glass fibers embedded in a polymer resin matrix, which when combined forms a strong and lightweight material suitable for a variety of applications.

Borax plays the role of a cross-linking agent in making polymer slime. It forms cross-links between the polymer chains, which helps to give the slime its unique stretchy and squishy properties.

The monomer or smaller unit of a carbohydrate is a simple sugar called a monosaccharide. Examples include glucose, fructose, and galactose. Monosaccharides are linked together to form complex carbohydrates like polysaccharides.

Polymer-polymer interactions refer to the attractive or repulsive forces that occur between different polymer chains. These interactions can influence the physical properties of the polymers, such as their solubility, mechanical strength, and thermal stability. Understanding and controlling polymer-polymer interactions is important for designing new materials with specific properties.

It is a really bad idea to put styrofoam, cling film, etc. in an oven and in contact with your food. You and I have no idea what kind of chemicals could be released and come in contact with your food, and in any event it is very likely there would be some melting or a product could catch on fire. Always use oven safe plates, baking sheets, pans, etc. in the oven and use microwave safe cooking tools in the microwave.

Yes you can. The maximum charge current for LiPo batteries is '1C' where 'C' is the capacity of the battery in question, in your case C is 2000mAH. So you will be charging at 0.5C which is fine.

A tent made from nylon is the most likely to be constructed using a polymer developed in a chemical laboratory. Nylon is a synthetic polymer that is commonly used in outdoor gear like tents due to its durability, water-resistant properties, and lightweight nature.

All monomers of addition polymers have a carbon-carbon double bond which can be broken during the polymerization process to form a long chain polymer.

Hydro gelplasters are used on wounds becausetheyreact to the state of the wound by either hydrating it or drying it. Wounds which have a lot of discharge or pus coming out of them are the ones they are usually used for as thehydro-gel absorbs this and lets the wound heal.

Natural polymer: shellac, amber, natural rubber, cellulose

Synthetic polymers: synthetic rubber, Bakelite, neoprene, nylon, PVC, polystyrene, polyethylene, polypropylene, silicone, etc.

In general organic contains carbon molecules and/or those related to life. It is the chemistry of carbon containing compounds.
Inorganic is everything else and generally do not contain carbon (with some exceptions).

Basically, in order to be able to see more clearly through it. Also, I noticed that if I dont blow the plastic-tight, then the wind has a tendancy to rattle and move the plastic sheeting back and forth so much that it will loosen and come unstuck from the window frame.

EPE, also known as pearl cotton, is also a new type of environmentally friendly material. It overcomes the shortcomings of traditional styrofoam, such as fragile deformation and poor recovery, and has the characteristics of shock resistance, water and moisture resistance, and recycling. It also has Good chemical resistance, becoming a substitute for traditional packaging materials

It's the monomer, the unit that repeats itself along the polymer.

crazy glue is cyanacrylate (ca) I believe, similar to what many model airplane builders use when building models
