Polyethylene and Polyterephthalate are Outdated

Abolished polyethylene terephthalate world is ready to buy new plastic Summary: This paper describes the structure of polyethylene terephthalate (also known as PET). It describes the nature of plastics and the way of recycling. My goal is to find out why PET is becoming the number one plastic, whether it is consumption or recycling. I also looked for new polymers that scientists created and compared them with PET to see if there are more environmentally friendly plastics.

(O) "Plastics" means polymers such as polyethylene terephthalate, high density polyethylene, vinyl, low density polyethylene, polypropylene, polystyrene resin, acrylonitrile butadiene benzene and the like. Ethylene, polyphenylene ether, polycarbonate and other various materials as essential ingredients.

The simplest and cheapest plastic produced by ethylene addition polymerization is polyethylene. Polyethylene has two broad categories, high density and low density. High density polyethylene is hard, strong, durable, resistant to chemicals and moisture, breathable, easy to process, easy to mold. It is used to make milk, juice, water bottle, cereal box liner, margarine barrel, and grocery store, garbage can, and retail bags. Low density polyethylene is flexible, durable, durable, easy to seal and moisture resistant. Because low density polyethylene is relatively transparent, it is mainly used for thin film applications and applications requiring heat sealing. Bread and frozen food bags, flexible lids and reflowable food bottles are examples of low density polyethylene. Polyethylene bags can be reused from time to time (including grocery stores and non-retail stores)

High density polyethylene (HDPE) is used for milk, water, juice bottles, yoghurt, margarine barrels, foodstuffs, garbage and retail bags. High density polyethylene is hard and durable, but it is not thermally stable (ie melts at relatively low temperature). I do not know if chemical substances that can cause cancer or damage hormones can be leaked and recycled. Polycarbonate is commonly used for the manufacture of refillable water bottles and plastic bottles for transparent, heat resistant, durable and sterilizable baby bottles, microwave ovens, dishes, and metal cans It is used. A small amount of bisphenol A is produced when washing polycarbonate bottles with heavy detergents or bleaching agents such as sodium hypochlorite. At high exposure levels, bisphenol A is potentially dangerous as it resembles female hormone estrogens .
