Higher line speeds, increased outputs, better adhesion, Ease of conversion, improved COF, printability, and better barrier are among the many performance improvements that are possible with the addition of PolyCal™.

Product Description

PolyCal™EC › 76% of a CaCO3 in LDPE
 
PolyCal™LC › 80% of a CaCO3 in LLDPE
 
PolyCal’s are specifically formulated for use in the wide range of extrusion coating resins currently used in this demanding high temperature process. PolyCal™ has been blended in at levels ranging from 5–30%, depending on the application.

What to Expect During Processing

• PolyCal™ concentrate can be added at levels ranging from 5-30% via side feeders at the hopper or using central blend stations.
   
• No changes in temperature profiles are required; however, optimized performance while maintaining adhesion may be possible with lower temperatures.
   
• Higher outputs and line speeds are often realized.

Physical Property Improvements 

PolyCal™ improves the coating adhesion of a variety of substrates, particularly flame-treated, clay-coated board without primer coating. PolyCal™ also modifies the coating surface which increases the surface energy and improves the print quality. Improved sheet feeding and converting performance and higher seal strengths are often realized. The mineral addition also improves the barrier properties and reduces both the coating WVTR and OTR.
