Synpro® Calcium Stearate 500 VEG

Product information

Product Name
Synpro® Calcium Stearate 500 VEG
Description

Synpro® CALCIUM STEARATE 500 Veg is a low ash powder specifically designed for use in polyolefins and surface critical applications. It acts as an acid scavenger to neutralize residual catalyst and provides lubrication in production / downstream processing.

Preferred for polyolefins due to its high purity which increases polymer miscibility while minimizing gel formation and plate out / build up on the extruder screen-packs during processing. Additionally, it is also used in rigid PVC siding, decking, profiles extrusions, and phenolics. The fatty acid component is derived from plant sources.
