what is plastic..??
Answers
Explanation:
Plastics are a wide range of synthetic or semi-synthetic organic polymers that are malleable and can be molded into solid objects during manufacturing processes. Because of their light-weight, durable and flexible properties and cheap production processes, plastics has been used for a wide range of products in contemporary society. Plastic typically are made through human industrial systems; most modern plastics are derived from fossil fuel based petrochemicals like natural gas or petroleum; however, more recent industrial methods use variants made from renewable materials such as derivatives of corn or cotton.[1] Plastics should not be confused with the general concept of plasticity, a property of all materials which can deform irreversibly without breaking.
Question:-
what is plastic..??
AnsWeR:-
Plastic is defined as a material that contains as an essential ingredient an organic substance of large molecular weight. It is also defined as polymers of long carbon chains. Carbon atoms are linked in chains and are produced in long chain molecules.
Example:-
The term plastic can be used as both an adjective and a noun. As an adjective, the term refers to any material that can be shaped or molded, with or without the application of heat. ... Substances such as nylon, Styrofoam™, Plexiglass™, Teflon™, and polyvinyl chloride (PVC) are examples of such materials.
Formula:-
PVC is Polyvinyl Chloride. This is a plastic that has the following chemical formula: {CH2=CHCl} see picture on the right.
Need Plastic:-
Plastic packaging serves several important functions in our modern lives, which are the primary reasons we rely on it: Protection: protects vulnerable products from damage whilst in transit and from contamination or damage by moisture, humidity, gases, microorganisms, insects and light.
