BACKGROUND
ADHESION MECHANISM
Adhesion principles between thermoplastic elastomer and the rigid substrate are governed by
three very important molecular factors which are the foundation of science behind good adhesive
behavior.
1.
In
some instances, good bonding exists even in the mechanism of adhesive failure.
The adhesion is categorized
based on adhesive failure (A)- if no TPE residue is left on the substrate or cohesive failure (C)- if
the failure is in TPE.

Cohesive (C) or adhesive (A).
The adhesion is
categorized based on adhesive failure (A)- if no TPE residue is left on the substrate or cohesive failure (C)- if the
failure is in TPE.
Based on adhesion
strength required by the consumer we have categorized an adhesion value higher than 12 pli to be acceptable
for adhesion.
