Posted By: Sm Adminon: November 29, 2015In: Miscellaneous

Rubber:
There are two types of rubber: one is natural and another is synthetic. Natural rubber is derived from the sap of the rubber tree. Synthetic rubber is derived from the crude oil.
Plastic:
The shape of plastic can be changed according to the requirement. Plastics are man-made. Plastics can be recycled after use. When the plastic is burned, it releases the poisonous toxic fumes which are harmful to the health.
Differences:

Basis	Rubber	Plastic
Definition (www.oxforddictionaries.com)	A tough elastic polymeric substance made from the latex of a tropical plant or synthetically.	A synthetic material made from a wide range of the organic polymers such as polyethylene, PVC, nylon etc. that can be moulded into the shape while soft, and then into rigid or slightly elastic form.
Synonyms	Soft, eraser, rubberized, gum, arctic and baleen	Molded, elastic
Antonyms	Good nature, good shape, good enough, good condition and good fortune	Inflexible, hard, unflappable and stiff
Pronunciation	Eng (UK): /ˈrʌbə / Eng (US): /ˈrəbər /	Eng (UK): /ˈplastɪk / Eng (US): /ˈplastik /
Types	Its types are: General purpose elastomers Special purpose elastomers Specialty elastomers	The types of plastics are: Thermoset or thermosetting plastics Thermoplastics
History	The first synthetic polymer was invented by John Wesley Hyatt in 1869.	Christopher Columbus invented the plastic in 1490’s.
Word origin	The word rubber was originated in 1632 from Latin plasticus of molding, from Greek plastikos, from plassein to mold, form.	The word plastic was originated in 1536.
Similarities	Rubber is a natural product which is derived from the sap of rubber trees.	Plastic is manmade, artificial or a by-product of oil.
Product	It is a natural product.	It is a by-product.
Derived from	It is derived from the sap of the rubber trees.	It is a polymer made from oil.
Components	It mainly consist of: Iso-propene Other organic compounds Water	It mainly consist of: Plasticizer Stabilizer Filler Pigments, etc.
Deformable	It is deformable.	It is non-deformable.
Elasticity	They are naturally more elastic.	They are less elastic in nature.
Toxicity	They have high toxicity because of their water content.	They have low toxicity because of their insoulubility in water.
Synthetic materials	Synthetic rubber is made from crude oil.	Synthetic plastic is made from natural gas or petroleum.
Made of	Rubber is made from the sap of tree; synthetic rubber is created from chemicals found in petroleum.	Plastics are human made.
Advantages/Benefits	Its advantages are that it is flexible and can be turned into any shape.	Its advantages are: Plastic is cheap to produce. Plastic is unbreakable. They possess good shock absorption capacity.
Disadvantages	Its disadvantages are that it expands when it is heated.	Its disadvantages are: Plastic is non-renewable resource. Plastic causes cancer. When it is burned it produces the poisonous gases harmful to the health.
