- Recommended Applications
STRUKTOL® Calcium Stearate is used by the rubber and plastic industries as an effective elastomer processing aid and release agent. The low chloride content of STRUKTOL® Calcium Stearate allows for complete product dispersion in elastomers.
STRUKTOL® Calcium Stearate reduces extruder pressure build-up of rigid PVC compounds when used as a processing aid during the manufacture of pipe, siding and injection molded fittings.
The low chloride content of STRUKTOL® Calcium Stearate meets the quality and processing demands of polyolefin, polystyrene and polyester manufacture.
STRUKTOL® Calcium Stearate can also be used as a processing aid in wire drawing operations, and as an anti-caking additive in dry blending operations. Some of the benefits of using STRUKTOL® Calcium Stearate are: -
- LOW IMPURITY : Reduces extruder pressure build-up and minimizes fiber breakage during extrusion and spinning.
- COLOR STABILITY :High-purity and a unique manufacturing process give this product extreme heat resistance to prevent discoloration and haze formation.
