Fabrication and Processing of Engineering Materials - Polymer Additives - Stabilizers

3 important questions on Fabrication and Processing of Engineering Materials - Polymer Additives - Stabilizers

How do stabilizers modify the polymer properties?

Stabilizers counteract the deterioration that happen under normal environmental conditions.

How do stabilizers protect from UV-deterioration?

1. By the addition of a thin UV-absorbent layer. (Sunscreen)
2. By the addition of a material that can react with the bonds broken by UV-light, so that crosslinking can not occur.

How do stabilizers protect from oxidation?

By consuming the oxygen before it can react with the polymer.
