Is plastic bottle mixture or pure substance?
Plastics that are encountered are generally mixtures. Some are mixtures of polymeric chains of differing lengths such as polyethylene. Some are mixtures that contain not only polymeric chains but have extra ingredients, fillers, plasticisers and coloring agents that modify the properties of the plastic. One example is PVC polyvinyl chloride which is a brittle substance but with the addition of plasticisers (phthalates), becomes flexible.
Is plastic a solid crystalline?
Some plastics are, some are not. Polymers like polyethylene and polypropylene can be partially crystalline. Typical commercial polystyrene is not crystalline, although a crystallized resin form (syndiotactic polystyrene) has been produced that resists deformation up to about 270 degrees C.
Will gas eat through plastic?
Depends on which plastic. Some will be affected by gasoline, some will not. I have plastic gas cans, and a tractor with a plastic gas tank.
Is synthetic fiber made from plastic?
Some are but others are not made from plastic but from other synthetic polymers.
What are some things that plastic fillers would be used for?
Plastic fillers can be used for all sorts of reasons. Some main reasons for the use of plastic fillers is to create mass inside of a object. This can be used for projects such as art.
Is polyethylene plastic safe to store food in?
some say yes
Different types of plastic?
There are a variety of types of plastic. Some of these include Polystyrene (PS), Low Density Polyethylene (LDPE), and Polyvinyl Chloride (PVC).
What type of plastic are wheelie bins made from?
High density polyethylene, though some bins are made from recycled plastics.
Items that are made from plastic?
Some of the Items made of Plastic are: 1) Ball Point Pen using Styrene(Type of Plastic) 2) Audio Cassette- Styrene 3) Electric Cable- PVC 4) Water Pipe- PVC 5) Tupperware- Polyethylene 6) Plastic Bag- Polyethylene 7) Refrigerator Liner- ABS and many more like this.........
What kind of plastic are milk jugs made from?
their made out of plastic or some even glass
What are bottle caps made of?
The caps on plastic 2-liter bottles of soda and bottles of water are made of plastic. Other bottle caps are made of steel, and some are made from aluminum lined with polyethylene.

someone please answer, or give your ideas. its a plastic polyethylene i think but im not sure which one. its for a plastic packaging class: is it lldpe, ldpe, pe
Why is polythene used to make bags?
Plastic bags can be made of different polymer types such as: High-Density Polyethylene (HDPE) Medium-Density Polyethylene (MDPE) Low-Density Polyethylene (LDPE) Linear low-density polyethylene Higher density polyethylene polymers have stronger cross-links for linking large chains to another which is usually how plastic bags are able to stretch more and can hold heavier objects. Hence being stronger.
Does alcohol react with plastic?
Yes, alcohol can react with certain types of plastic. Some plastics, such as polyethylene terephthalate (PET) and high-density polyethylene (HDPE), are resistant to alcohol and do not interact with it. However, other types of plastic, such as polyvinyl chloride (PVC) and polystyrene (PS), can be sensitive to alcohol and may degrade or become brittle over time when exposed to it. It is important to consider the type of plastic that is being used when storing or coming into contact with alcohol.
What type of plastic sheet should I get for making simple electronics cases I am looking for some cheap one?
Polyethylene and polymethyl metacrylate are among those suitable.
How was polyethylene discovered?
Polyethylene is the accidental plastic--as in they synthesized it by accident three or four different times. Someone was heating some diazomethane, and polyethylene just precipitated out of solution. Someone else compressed a mixture of ethylene and benzaldehyde to 6000 psi and polyethylene just precipitated out of solution. And the Philips company of the Netherlands attempted to make high-density polyethylene in the 1950s, and accidentally made two million pounds of medium-density polyethylene before they finally got it right. (They then invented the Hula Hoop to use up all the bad polyethylene.)
What health concerns might be associated with having an Orlando International Airport job?
There are some general health concerns associated with working at large airports, mainly having to do with airport noise and pollution. Noise pollution has been linked to heart disease and stroke.
