A filler can not be used to the best of advantates in polymer unless there is a good adhesion between them. In particular, the filler particle / polymer interface will note be stress bearing and therefore provides a point of mechanical weakness. Calcium stearate / Stearic acid surface is produced by chemical reaction with calcium carbonate substrate – (MICRO COATING PROCESS), hence the treatment is firmly bonded to the surface of the particle. Thus it is not a physical coating or a mixture and therefore will neither wash off in processing nor segregate during process.
Advanages for Polymer
Rapid and complete dispersion
Very low abrasion at high loading
Very low moisture content
Good compatibility with polymers and other additives
Better impact strength with polymers and other additives
As compared to uncoated material
Increased production rate
Increased flow rate
Better HDT
Recommended Applications
PP Compounding (Automotive, Furniture , Crates)
Rigid PVC Pipes
Antifabrillliant additive Master batches for
PP & HDPE woven sacks
Additive Master batches for paper like LLDPE films
