“Best in Class” stabilisation of aliphatic polyamides

BRUGGOLEN® TP-H1804 is a new, highly effective heat stabiliser from Brüggemann for use with aliphatic polyamides at continuous service temperatures between 160 °C and 190 °C. It complements BRUGGOLEN® TP-H1805, which stabilises reinforced polyamides at temperatures above 200 °C. The masterbatch, supplied in granular form, can be dosed very precisely, and thus in a very targeted manner.

High-performance Additives for PA and Recycled PE

Brüggemann (www.brueggemann.com) is presenting performance-enhancing additive innovations at K 2022. These range from electrically neutral heat stabilizers for polyamides in electrical and electronic applications, for example for e-mobility, to high-performance stabilizers for exposure to moderate to very high temperatures and additives for stabilizing recycled polyolefins. A further focus is on efficiency-boosting flow enhancers which enable shorter cycle times and low wall thicknesses for components made of polyamides and polyesters (PBT).

New heat stabilizers of polyamides

BRUGGOLEN® TP-H1607 and BRUGGOLEN® TP-H1805 are additions to Brüggemann's extensive additive portfolio for polyamides. These newly developed antioxidant blends allow polyamide materials to exceed current performance limits and offer exciting opportunities for the compounding industry.

Phenolic Plus BRUGGOLEN® TP-H1803

Brüggemann's Phenolic Plus BRUGGOLEN® TP-H1803 is a new heat stabilizer for polyamides designed to outperform conventional phenolic/phosphite based stabilizers, i.e. blends of sterically hindered phenolic antioxidants with organic phosphites. BRUGGOLEN® TP-H1803 bridges the price-performance gap between these blends and copper based stabilizers.

New flow enhancer

BRUGGOLEN® TP-P1810 from Brüggemann is the first flow enhancer for semi-aromatic polyamides which is available on the market. This product joins BRUGGOLEN® TP-P1507, which is already used worldwide for aliphatic polyamides such as PA6, PA6.6 and PA12. As a result, the company now offers flow enhancers for the entire polyamide spectrum. Both BRUGGOLEN® TP-P1810 and BRUGGOLEN® TP-P1507 demonstrate very significant improvement in melt flow while retaining the mechanical properties of finished components. Supplied in pellet form, they are easy to dose and disperse during direct injection molding and compounding.

Stabilizers for high-quality polyolefin recyclates

Brüggemann and Fraunhofer LBF have joined forces to successfully tackle one of the seemingly insurmountable problems of plastics recycling. During their lifetime, plastic articles are subjected to thermal oxidation and photo-oxidation, which can create enough damage to prevent them from being recycled into high-quality products. In order to overcome this problem, researchers at the Fraunhofer Institute for Structural Durability and System Reliability LBF, Darmstadt, have developed new stabilizer systems to improve the properties of polyolefin recyclates, especially those made of polypropylene and polyethylene.

Upcycling from polyamide waste

When recycling polyamides, Brüggemann's BRUGGOLEN® M series of reactive chain modifiers allow precise and reproducible adjustment of relative viscosities, by either lengthening excessively short chains or shortening those which are too long. Producers can use small amounts of these modifiers to tailor relative viscosities to their needs in a single compounding step. The resultant upcycled materials exhibit excellent mechanical properties and are suitable for the same applications as prime materials of similar viscosities. This removes the need to blend the recyclate with prime polymers and opens up a wide range of possibilities for establishing a profitable market for secondary polyamide raw materials which meet the high-quality requirements of the molding industry.
