Baerlocher announces its participation at the PRSE Virtual conference from 9-11 December 2020. The company will share latest experiences with its Baeropol T-Blend range.
Stabilizers in a Dust-free Pastille Form
Baerlocher offers fully formulated antioxidant packages under the Baeropol T-Blend range of products. The stabilizers from Baerlocher are available in a dust-free pastille form, much appreciated by recyclers, who often struggle to handle powder materials. Unlike additives in masterbatches, these products have 100% active content.
The pastilles can be fed directly into the compactor unit of a film recycling line by using low cost volumetric feeders. The improved quality of the recyclate is then quickly made visible in, for example, a downstream film blowing line, where less gelling and fewer degradation products lead to fewer bubble breakages and a more homogenous mechanical performance of the film.
Baerlocher´s Technical Product Manager Henrik Eriksson comments: “
Since the K-Show we have gathered a lot more data that show the benefits of our products, which we are now excited to share with recyclers, converters and brand owners at the PRSE Virtual. We want to highlight how our analytical work can provide the tools recyclers need to communicate the higher value of recyclate upcycled with Baeropol additives.”
One of the Baeropol T-Blends not only safeguards processability and mechanical properties, but it also makes polypropylene solidify faster and more uniformly in the mold. This enables shorter cycle times and ensure the dimensional stability as the producer moves from batch to batch.
Upcycling Low Value HDPE for Use in Higher Value Applications
Another Baerlocher specialty product is aimed to remedy the supply-and-demand mismatch between low melt strength HDPE from post-consumer waste and high melt strength HDPE for pipe extrusion and extrusion blow molding of large parts.
This additive acts as a chain extender and allows a compounder to upcycle low value HDPE for implementation in higher value applications. In customer evaluations it has been shown that modification with this chain extender can rid flow instabilities in recycled HDPE, which cause a rough surface appearance on extruded profiles.
The modification is also able to remove the rotational memory effect that can sometimes occur in profile extrusion, i.e. a tendency of the profile to rotate in the direction of the extruder screw as it exits the die. The product is also capable of mitigating negative effects from having a minor part of PP or PE present in one of the two polymers, steering the properties in the direction of the pure majority resin, by acting as a compatibilizer.
