Question

Blastic of stretchable​

Answer 1

Plastics tend to either deform permanently, or just plain break, when you stretch them too hard. ... But at the same time, if you pull hard enough, you can not only stretch a plastic, but it will stay in the shape you stretched it into once you stop stretching it.

Some plastics stretch and are very flexible. Other plastics, such as polyethylene, polystyrene (Styrofoam™) and polyurethane, can be foamed. Plastics can be molded into drums or be mixed with solvents to become adhesives or paints. Elastomers and some plastics stretch and are very flexible.

To summarize, there are 7 types of plastic exist in our current modern days:

• 1 – Polyethylene Terephthalate (PET or PETE or Polyester) ...
• 2 – High-Density Polyethylene (HDPE) ...
• 3 – Polyvinyl Chloride (PVC) ...
• 4 – Low-Density Polyethylene (LDPE) ...
• 5 – Polypropylene (PP) ...
• 6 – Polystyrene (PS) ...
• 7 – Other.
