Significant savings on raw material costs
Realized savings can vary from $0.02-$0.06 per lb, depending on
percentage of PolyMax™ used.

Improved Productivity
- Significantly reduced cycle times.
- Improved processablity, reduced amps.
- lower pressure, and higher outputs.
Better part performance
- Increased stiffness.
- Improved ESCR.
- Reduced warpage.
Product Description
PolyMax™ CaCO3
concentrates are designed to improve the performance of blow molding
applications. PolyMax™ concentrates
contain 76%-80% of fine ground, surface treated CaCO3
combined with various polyolefin carrier resins.
Products Available
PolyMax™ LC 80% CaCO3 in LLDPE to
balance cost & performance.
PolyMax™ HD 76% CaCO3
in HDPE to maximize stiffness and top load. Typical usage levels of PolyMax™ CaCO3
concentrates:
10-20% depending on targeted application.
What to Expect During Processing
No temperature changes are needed. Lower extrusion amps and
pressure are often experienced due to lower melt viscosity. Minor
adjustments to the shot size may be required to compensate for
extended parison. Final part appearance will be relatively
un-affected:
- Un-pigmented parts will appear uniformly white.
- Colored parts may require reformulation of the color
masterbatch.
- PolyMax™ concentrates can be added using standard
additive feeders.
Productivity Gains
A major advantage of PolyMax™ concentrates is their ability to
increase the thermal conductivity of the part in blow molding
processes. Addition of mineral results in cooler parts; cycle times
are be reduced, sometimes by as much as 30%. The final bottle or
part will have significantly less warpage even at the reduced cycle
time. 
Physical Property Improvements
PolyMax™increases part density based on the loading level. Part
weight should be maintained to maximize material cost savings. The
reduction in wall thickness required to maintain part weight is
5-11% depending on the usage level of PolyMax™. This will result
in:
- Impact and top load strength unaffected.
- ESCR improved (Stress Crack Resistance).
- Part will feel stiffer.
- Warpage reduced.
