In this blog post, we discuss the adhesion capability of different high performance polymers.
In
general, adhesion bonding has several advantages compared to mechanical (screw
based) connection methods:
-
Glue joints
allow a more uniform force distribution over the entire adhesive surface (especially
under mechanical stress).
-
Reduction of stress peaks
-
Reduction of material damage due to drilling holes
-
Weight reduction
-
Excellent sealing properties
- Combination of different materials
There are several industrial
adhesives available on the market. Selection of the optimal adhesive is not
only dependent on the polymer compound, but also on the use conditions of the
final part. The adhesive can enable a flexible or stiff bonding between the
plastics. Also, there are adhesives which are temperature and chemical
resistant. Furthermore, they can be electrical isolating or electrical
conductive.
High performance polymers
are not easy to bond since they have a high chemical resistance towards
solutions. The chemical resistance of high performance polymers we discussed here.
However, even for extreme chemical resistance polymers such as PTFE and PVDF,
adhesives are available.
