Polyethylene terephthalate (sometimes written poly(ethylene terephthalate)), commonly abbreviated PET, PETE, or the obsolete PETP or PET-P), is a thermoplastic polymer resin of the polyester family and is used in synthetic fibers; beverage, food and other liquid containers; thermoforming applications; and engineering resins often in combination with glass fiber.

What are the different types of plastics?
Types of plastic - polyethylene (HDPE or LDPE) found in plastic bags and shampoo bottles - polystyrene (PS) found in computer cases - polypropylene (PP) found in dishwasher safe containers - polyethylene terephthalate (PET) found in soda bottles - polyvinyl chloride (PVC) More generally speaking in engineering, plastics are divided into thermoplastic plastics and thermoset plastics These are based on their properties upon reheating after the plastic is molded. Thermoplastic plastics when heated will melt whereas thermoset plastics will not melt but only burn This is due to the way the branches of polymers coordinate. Thermoplastic plastics governed by largely van der waals forces. Thermoset plastics are crosslinked by covalent bonds
What type of plastic is a shampoo bottle made from?
Many bottles now are actually made of poly-beta-hydroxybutyrate which is biodegradable. It's made in bacteria that uses this compound to store extra carbon, so there are enzymes that degrade it, in contrast to plastic, which takes hundreds of years to degrade.
What is the use of polyethylene glycol for the human body?
"Polyethylene glycol has many uses, including many related to the human body. Polyethylene glycol or PEG is used in many laxatives. It is also found in many eye drop lubricants, toothpastes, skin creams and sexual lubricants."
What are the 3 main uses of ships?

Types of plastic?
Polypropylene (PP) Food containers, appliances, car fenders (bumpers). Polystyrene (PS) Packaging foam, food containers, disposable cups, plates, cutlery, CD and cassette boxes. High impact polystyrene (HIPS) Fridge liners, food packaging, vending cups. Acrylonitrile butadiene styrene (ABS) Electronic equipment cases (e.g., computer monitors, printers, keyboards), drainage pipe. Polyethylene terephthalate (PET) Carbonated drinks bottles, jars, plastic film, microwavable packaging. Polyester (PES) Fibers, textiles. Polyamides (PA) (Nylons) Fibers, toothbrush bristles, fishing line, under-the-hood car engine mouldings. Polyvinyl chloride (PVC) Plumbing pipes and guttering, shower curtains, window frames, flooring. Polyurethanes (PU) Cushioning foams, thermal insulation foams, surface coatings, printing rollers. (Currently 6th or 7th most commonly used plastic material, for instance the most commonly used plastic found in cars). Polycarbonate (PC) Compact discs, eyeglasses, riot shields, security windows, traffic lights, lenses. Polyvinylidene chloride (PVDC) (Saran) Food packaging. Polyethylene (PE) Wide range of inexpensive uses including supermarket bags, plastic bottles. Polycarbonate/Acrylonitrile Butadiene Styrene (PC/ABS) A blend of PC and ABS that creates a stronger plastic. Used in car interior and exterior parts, and mobile phone bodies.

Can polyethylene terephthalate react with alcohol?
It depends on the type of alcohol in question. Part of the recycling process involves reacting PE with ethylene glycol in order to retrieve the original monomers that can be re-polymerized into new plastic. Though not as widely used anymore, there is a similar reaction that uses methanol instead of ethylene glycol to isolate the dimethyl terephthalate monomer. So in short, yes alcohols can react with PE but it is usually not at STP.
What is the difference between ethylene glycol and polyethylene glycol?
Ethylene glycol is a simple compound used in antifreeze, while polyethylene glycol is a larger molecule used in various products like cosmetics and medications. The main difference is in their chemical structures and uses.

What is poy polyester?
Polyester, specifically referred to as PET (polyethylene terephthalate), is a synthetic polymer used widely in textiles and packaging. Poy polyester, or partially oriented yarn polyester, is a type of polyester filament that is only partially stretched during production, resulting in a yarn that is less rigid and more flexible than fully oriented yarns. This characteristic makes poy polyester suitable for various applications, including textiles and industrial uses. It can later be fully oriented during processing to enhance its strength and durability.
