Improved performance

• Productivity – Faster cycle time, higher outputs.
   
• Dimensional Stability – Less warping and reduced shrinkage.
   
• Final Product – Higher impact, increased stiffness, lower CLTE, and improved ESCR.

Product Description

HiCal™ and HM10® concentrates contain up to 80% fine ground, surface treated CaCO3 in various polyolefin carriers: PP (HiCal), HDPE and LLDPE (HM10).

• CaCO3 concentrates are able to reduce the raw material cost of injection molding applications currently using filled or press ready compounds.
   
• New molds can be designed for the use of mineral concentrates. Advantages - cost and performance.

Products Available

HiCal™LC › 80% CaCO3 in PP
 
HM-10® Max › 80% CaCO3 in LLDPE
 
HM-10® HD › 76% CaCO3 in HDPE

What to Expect During Processing

1. No changes in the temperature profiles are required.
    
2. Lower extruder amps and pressures are often realized as a result of lower melt viscosity.
    
3. 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.
   
• Deep colored parts may require reformulation.

Physical Property Improvements

• HiCal™ concentrates are designed to produce parts that are equal to the physical properties of current filled PP compounds.
   
• HiCal™ and HM10® are designed to achieve full dispersion and distribution of CaCO3 particles during injection molding processes.
   
• Increased impact strength and stiffness are possible with the reinforcing effects of CaCO3 concentrates.

Raw Materials Savings

• For products based on a formulated, press ready compound, changing to a HiCal™ or HM10® concentrate can provide significant savings.
   
• Use of HiCal™ and HM10® in resin only systems can provide additional productivity and performance improvements.
