Why is plastic durable?

Answer 1

There are multitudes of plastics, and they vary widely in their mechanical properties. It is not possible to assign a tensile strength to "plastic" as there are so many.

Answer 2

Plastics are polymers and they are made by bonding molecules together. These molecules are cross linked in three dimensions and the bond created between molecules is strong, hence making plastic one of the toughest synthetic materials around.

Answer 3

As you know plastic is a polymer which is made up of lots of simple monomers. In plastic the chains on monomers are all tanlged up but easily slide other each other; which is why they are flexible.

Answer 4

Plastic has proved to be a very convenient and economical material for the manufacture of a very large range of useful products. Everything made from plastic could be made instead of other materials, such as ivory, wood, metal, glass, rubber, etc., however such alternatives would be more expensive, and thus less affordable for large numbers of people.

Answer 5

Plastic, is in most cases, waterproof and does not rust nor decay via natural means! It is usually pliable at least when heated, and will absorb strikes / stress via the absorption of the stress by bending and compressing without breaking. Most plastic is impervious to most acids, sugars, salts, etc.

Answer 6

Plastic is durable because it is made up of long chains of polymers, which are strong and resistant to breaking. Additionally, some plastics are designed to be resistant to heat, chemicals, and weathering, making them more durable in various environments.

Answer 7

Because the fibre is as strong as the fibre in wood for example, because the fibres in plastic can bend hugely.
