Single-use plastics, or disposable plastics, are used only once before they are thrown away or recycled. These items are things like plastic bags, straws, coffee stirrers, soda and water bottles and most food packaging. We produce roughly 300 million tons of plastic each year and half of it is disposable! World-wide only 10-13% of plastic items are recycled.
Polyethylene is a polymer made of repeating ethylene units. It is used in many makeup products such as eyeliners, mascara, eye shadows, eyebrow pencils, lipstick, blushers, face powders and foundations, as well as in skin cleansers and skin care products.

PETE is a durable, transparent plastic commonly used to make beverage and food product bottles and jars as well as microwaveable food trays and ovenproof plastic wrap. When recycled, it becomes part of new plastic containers, carpet yarns, polyester textiles, …
Polyethylene glycol (PEG) is made from ethylene glycol (ethane-1,2-diol), the main ingredient in antifreeze. When ethylene glycol (molecular weight, 62.07) polymerizes, reacts with itself (in water), the reaction yields a variety of products containing varying numbers of ethylene glycol units.
The History of Polyethylene. Today, Polyethylene has the advantages of excellent moisture-vapor, chemical, and electrical resistance. It is widely used for making containers, wire cable insulation, pipe, linings, coatings, and engineered films. It is used to power transmission, consumer goods, packaging, electronics good and more.
Adhesives and solvents are rarely used because polyethylene is nonpolar and has a high resistance to solvents. Pressure-sensitive adhesives (PSA) are feasible if the surface chemistry or charge is modified with plasma activation, flame treatment, or corona treatment. Classification. Polyethylene is classified by its density and branching.
Polyethylene is also used to make the coatings that you see on fruit juice boxes. Though the container is mostly made of out cardboard type material with a small amount of plastic mixed in, the outer coating that keeps the box from falling apart once the liquid has been introduced is the Polyethylene.
Nov 01, 2018· Polyethylene Glycol 3350, USP Powder for Oral Solution should not be used by children. It should not be used by pregnant women unless prescribed by a physician. Side Effects/Drug Reactions. Occasionally, Polyethylene Glycol 3350, USP Powder for Oral Solution may cause nausea, stomach fullness, cramping, diarrhea and/or gas.
Polyethylene glycol 3350 is used to treat occasional constipation. Polyethylene glycol 3350 is in a class of medications called osmotic laxatives. It works by causing water to be retained with the stool. This increases the number of bowel movements and softens the stool so it is easier to pass .
The groups of atoms that are used to make unit cells are called monomers. For some plastics, such as polyethylene, the repeat unit can be just one carbon atom and two hydrogen atoms. For other plastics, such as nylons, the repeat unit can involve 38 or more atoms. When we combine monomers, we generate polymers or plastics.
Polyethylene is used in applications ranging for films, tubes, plastic parts, laminates, etc. in several markets (packaging, automotive, electrical, etc.). Polyethylene is made from the polymerization of ethylene (or ethene) monomer. Polyethylene chemical formula is (C 2 H 4) n.
Polyethylene terephthalate (PETE or PET): PET is the most widely produced plastic in the world. It is used predominantly as a fiber (known by the trade name "polyester") and for bottling or packaging. For example, PET is the plastic used for bottled water and is highly recyclable. PET …
Aug 31, 2019· Polyethylene plastic is an inexpensive plastic material that is chemically resistant and can be very durable. Polyethylene plastic comes in a low density form and a high density form. The low density form was discovered first, followed a few years later by the high density form.
Industrial Uses of Polyethylene. While LLDPE and LDPE are highly preferred for electrical insulation and film packaging, HDPE is used for manufacturing chemical containers and drums for various kinds of industrial packaging as well as in the piping industry. The following table illustrates the applications of these three types of Polyethylene compounds.
Polyethylene sheeting (film) has a big role in offering plastic protection. It is used in construction as vapor retarders, window films, flooring and counter top protection, and even in roofing. It is used in construction as vapor retarders, window films, flooring and counter top protection, and even in roofing.
Aug 31, 2019· Polyethylene is widely used to make plastic bottles for milk, soda and other beverages.
This density of polyethylene is ductile and used to make products like shopping bags, plastic bags, clear food containers, disposable packaging, etc. Possessing more polymer chains and, thus, greater density, MDPE is typically in gas pipes, shrink film, carrier bags, screw closures, and more.
polyethylene glycol a polymer of ethylene oxide and water, available in liquid form (polyethylene glycol 300 or 400) or as waxy solids (polyethylene glycol 1540 or 4000), used in various pharmaceutical preparations as a water-soluble ointment base. Polyethylene glycol is also used as a laxative.
Polyethylene, light, versatile synthetic resin made from the polymerization of ethylene. Polyethylene is a member of the important family of polyolefin resins. It is the most widely used plastic in the world, being made into products ranging from clear food wrap and shopping bags to detergent bottles and fuel tanks.
Jan 17, 2019· Learn about polypropylene, the versatile plastic that is used throughout daily life and has become a common piece for packaging and plastic products. Menu. Home. Learn the Basics of the Plastic Resin Polypropylene. . though it is not as sturdy as other plastics such as polyethylene.
Common Uses of High-Density Polyethylene High-density polyethylene or HDPE is a commonly used petroleum thermoplastic and the most used of the three polyethylenes for a wide range of applications. If you look at this plastic under a microscope, you would see that it has a linear structure with few branches lending to its optimal strength/density ratio.
Polyethylene is the base plastic used to make high-density polyethylene known as HDPE. Shampoo bottles, food containers, milk jugs and more come from HDPE plastics while lower density versions of polyethylene make the plastic wrap used in your kitchen.
The Plastic Commonly Known as PET. PET plastics or polyethylene terephthalate is used in many different products. The properties of PET makes it ideal for a number of different uses and these advantages make it one of the most common plastics available today. Understanding more about the history of PET, as well as the chemical properties,.
(polyethylene terephthalate) PET (also abbreviated PETE) is short for polyethylene terephthalate, the chemical name for polyester. PET is a clear, strong, and lightweight plastic that is widely used for packaging foods and beverages, especially convenience-sized soft drinks, juices and water.
Polyethylene sheeting under concrete slab. Under-slab vapor retarders play a very important role in retarding moisture from coming up through the concrete and into the structure. Today most experts feel very strongly that engineered films designed specifically for use as vapor retarders should be used …
