What are some of the problems with polymers?

Answer 1

Disadvantages of polymers are:

- non bio-degradable

- easily breakable

- flame retardancy is low

- when polymers incorporated with additives are burnt they emit a lot of poisonous gases into the atmosphere

- low molecular weight polymers (Polyethylene bags) are difficult to recycle

- improper disposal leads to environmental pollution

- undergo oxidation and ozonation easily

Answer 2

In the production stage, polymers are susceptible to contamination. Any varieties in heat and timing in the molding process , the final product will corrupt

They can produce toxic gasses when exposed to fire

Answer 3

The same as the drawbacks of anything specialized: you can only use them for a limited range of applications, and the company that makes them charges a large sum of money for them.

Because of this, most people will design their product so it can use a modified form of a standard polymer. Say you are designing a nylon gear, but it has to weigh more than a part made from pure nylon. If you add a little powdered steel to the nylon, you can increase the weight and still use the standard nylon resin.

Answer 4

polymers are very cheep to manurfacture and also can be constructed relitivily quickly, further more they are thermo setting and thus do not melt.

Answer 5

Cost! more expensive to produce
