Research of impurities in your polymers in laboratory

An impurity is an element that enters the composition of a material during its production as an undesirable additive. The impurities of a polymer are favorable to aging, they can accelerate its degradation.

Indeed, the presence, after manufacturing, of residues, in particular of peroxide (used to initiate polymerization), can induce the degradation of the polymer. Thus, a minimal amount of peroxide must be used during the manufacture of polymer materials.

Moreover, the impurity zones are particularly weakened zones. Indeed, these are areas where the density of entanglements is lower leading to geometrical defects (cracking).

Therefore, it may be advisable to carry out a search for impurities by a specialized laboratory.
