polyester is the same thing as plastic. plastic is a type of polyester so it is still the same thing. polyester does repel water the same way plastic does too. plastic and polyester repel water equally
Synthetic materials are man-made materials. Examples are: 1.polystyrene, 2.Polyethene, 3.polyester, 4.spandex,
Polyester is spelled and pronounced the same in German.
They are made from the same polymer, polystyrene. Usually polystyrene is clear, hard and rigid, for example in CD cases. However, styrofoam is created by blowing air through liquid polystyrene. The bubbles are locked in the polystyrene as it solidifies, giving the syrofoam used in packaging and cups. The reason it is compressible is because the air is compressed, rather than the hard, rigid polystyrene itself.
Both 1kg of lead and 1kg of polystyrene have the same mass, despite lead being much denser than polystyrene. Density is defined by mass divided by volume, so if the mass is the same, the volume must differ to maintain the same density. In this case, the volume of lead will be significantly smaller than the volume of polystyrene, making them have the same density.
No, iron is denser and heavier than polystyrene. An iron ball would weigh more than a polystyrene ball of the same size.
No, PE is an abbreviation for polyethylene. The abbreviation for polyester (polyethylene terephthalate) is PET.
No. That would be like saying wood is the same a boat. Polyester is a material. Knit is what can be done with polyester to turn it into a fiber, but knitting can also be done with cotton, silk, wool, and other materials.
They both weigh the same !
Polystyrene is NOT biodegradable
Rigid polystyrene is a hard plastic Rigid polystyrene is a hard plastic
One knits with polyester yarn in much the same way that one knits with any other type of yarn.
