Wear Test Results
Wear data was similar for both composite materials tested, despite the fact that the glass and
pre-polymerized filler particles in the KALORE without DuPont matrix were disrupted due to
shrinkage forces. This can be explained by the protective action of the innovative and newly
developed pre-polymerized fillers that are highly loaded with 400 nm glass filler and heat-cured.
the relatively high content of pre-polymerized fillers protects the resin effectively against three-
body wear.
4a. KALORE x2000 after 100,000 cycles.
note the continuous interface between the pre-polymerized fillers and the
resin matrix.
4b. KALORE without DuPont x2000 after 100,000 cycles.
note the gap at the interface between the pre-polymerized filler and the resin
matrix. Additionally, voids can be observed where fillers were lost.
4c. KALORE without DuPont x2000 after 100,000 cycles.
Note the loss of pre-polymerized fillers and glass particles from resin matrix.
