Technical Details & Test Data


The addition to the polymer melt is best done by compounding on twin screw extrusion machines. Only this will lead to the desired optimum dispersion of the stabilizer in the compound. Dry blending of BRUGGOLEN® H3386 along with polymer granules will not lead to an optimum dispersion of the additive in the melt. However, to support the dispersion of BRUGGOLEN®H3386 when making a dry-blend, it is recommended that our BRUGGOLEN®P60 as adhesive agent is used.
