PET (polyethylene terephthalate), this is plastic recycling type #1
Bottle caps are made not out of PET plastic because that would make the separation from the bottle imposible, PET does not float, so the caps have to be HDPE, PP or other plastic that is less dense than water, thus makin the separation process posible when the bottles are recycled.
- the polyethylene plastic bottle is unbreakable- the glass has a solubility (low and dependent on the type of glass) in acids
Plastic.. Depends what type, but plastic pipes are made from plastic. :)
Usually nylon.

Most plastic do not conduct heat very well, This makes it ideal for handles on pans which makes it Thermoset.
size shape (smooth sides/jagged sides) type of plastic it is made from
a high density poly ester (HDPE)....a type of plastic

It depends on the size, of course, and the thickness, but a small bottle contains about 20 grams of plastic.

Plastics make up the majority of bottle caps. They might also be created from metal. Based on its intended use and the type of bottle or container, the material used to make bottle caps is selected.
The polyester fleece is basically a type of plastic, and is similar to PET (polyethyl terpthalate) which is used to make 2 liter soda bottles. The difference between fleece and bottle is how the polyester is made into a thread instead of a solid bottle.
