What to Expect During Processing
- No changes in the temperature profiles are required.
- Lower extruder amps and pressures are often realized
as a result of lower melt viscosity.
- Color concentrates are added separately to the
injection molding process and the final part appearance is
relatively unaffected:
- Un-pigmented parts will appear uniformly white.
- Colored parts may require reformulation.
Productivity Gains
A major advantage of using calcium carbonate concentrates in
polypropylene thermoforming is their ability to increase the thermal
conductivity of the sheet and the molded part.
- Addition of mineral enables faster sheet line
speeds.
- Faster sheet heating and part cooling after
forming can be observed.
Physical Property Improvements
Calcium carbonate addition will increase the part density
depending on the amount of concentrate used. To maximize cost
savings, part weights should be maintained by reducing wall
thickness from 4-8% depending on the level of concentrate used.
