Product Description
PolyMax™ CaCO3
concentrates are designed to improve the performance of blow molding
applications. PolyMax™ concentrates
contain 80% of fine ground, surface treated CaCO3
combined with various polyolefin carrier resins.
Typical usage levels of HM10 Max™CaCO3
concentrates: 10-20% with 15% in pipe typical.
What to Expect During Processing
No temperature changes are needed. Lower extruder amps and
pressure are often experienced due to lower melt viscosity. Minor
adjustments to output or line speed may be required to compensate
for increased pipe weight. Final part appearance will be relatively
unaffected:
Surface gloss will be diminished.
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 pipe in the extrusion process. This allows higher outputs,
allowing faster pipe production to main- tain the pipe weight.
Physical Property Improvements
PolyMax™ increases pipe stiffness
allowing the needed reduction in wall thickness to maintain pipe
weight. 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.
