​

Answer 1

Advantages of plastic:

 Advantages of plastic are light in weight.

 They can be easily moulded and have excellent finishing.

 They possess very good strength and toughness. They possess good shock absorption capacity.

 Advantages of plastic are corrosion resistant and chemically inert.

 They have low thermal expansion of co-efficient and possess good thermal and electrical insulating

property.

 Advantages of plastic is very good water resistant and possess good adhesiveness.

 Plastic is strong, good and cheap to produce.

 Plastic is a recycling process and it does not decompose.

 Plastic bottles can be reused and restored over again and again.

 Advantages of plastic are used to produce another product.

 Used to reduce soil and wind erosion.

Disadvantages of plastics:

 Plastic is a nonrenewable resources.

 Plastic is softness.

 causes CANCER

 Disadvantage of plastics are embrittlement at low temperature.

 Disadvantage of plastics are deformation under load.

 Disadvantage of plastics are low heat resistant and poor ductility.

 Disadvantage of plastics are combustibility.

 Produces toxic fumes when it is burnt

 It is a recycle process, but it is very costly.

Answer 2

Answer:

The disadvantage of plastic are:

• 1) Plastic bags thrown carelessly on roads get into drains and the sewer system and choke them. As a result sewage water spills on road and causes spread of diseases.

• 2) Plastics give out harmful gases upon heating or burning which causes air pollution and many health problems.

• 3) Plastic bags filled with garbage is thrown away in the open. When stray animals look for food in these bags, they swallow plastic bags along with food. 

Advantages of Plastics are many-

• made from residual content of petrol/diesel, propylene and ethylene gas are the raw materials for polypropylene and polyethylene.

• Requires less heat (than metal or glass) for giving a shape.

• Can replace wood (from chairs, furnitures and what not).

• Plastics have been into your clothing (everything bother than cotton and wool is Plastics), so that mankind can grow more food in field instead of cotton.

• Plastics have replaced leather too.
