what are some positive and negative effects of polymer use?

Answer 1

Positive effects:
Cleaner (regarding the consumer), cheaper, easier to manufacture than other materials (Formability), lighter (less weight), better toughness (Impact resistance), poor electrical and thermal conductivity (Yes, it is a positive) , good corrosion resistance and high chemical stability.

Negative effects;
Less likely to be reusable and secondary use, very long time to degrade (Remains long time in the environment), Sometimes releases toxic compounds on burning or degrading, generally poor heat resistance, not very good for high precision manufacturing
