What advantages are gained by using plastic conveyor chains?
There are a number of potential advantages to using plastic conveyor chains. Some of these advantages include being 40% lighter than metal covers, they require small motors and use less energy.
What alternatives are there to a plastic keychain?
There is always an alternative to plastic key chains. While some people prefer plastic, others prefer them to be made of something else like leather or metal.
Can a thermosetting plastic change shape?
No because of cross linking of monomeric chains. On heating it chars.
Why plastic is elastic?
Plastic is elastic due to its molecular structure, which allows its polymer chains to stretch and return to their original shape. This property makes plastic flexible and able to deform without breaking, making it ideal for a wide range of applications.
Where can one buy plastic key chains for kids?
Plastic key chains for children can be found in novelty shops and convenience stores around the world. Theme parks and vacation resorts also stock a large variety of children's key chains.

A plastic in science is a compound because it is made up of many single cell monomers which are chemically reacted and combined to form long chains called polymers which make plastic.
What are the advantages and disadvantages of using a plastic bike chain compared to a traditional metal chain?
Advantages of using a plastic bike chain include lighter weight, quieter operation, and resistance to rust and corrosion. Disadvantages may include lower durability and strength compared to metal chains, potentially leading to quicker wear and tear.
How does sulfuric acid affect the degradation of plastic materials?
Sulfuric acid can break down plastic materials by reacting with the polymer chains, causing them to weaken and degrade. This can lead to the loss of structural integrity and physical properties of the plastic.
Is plastic acid or base?
Plastic is neither an acid nor a base, as it is a polymer made up of long chains of organic molecules. Its chemical properties depend on the specific type of plastic used, but in general, plastics do not exhibit acidic or basic behavior.
