Heat Stabilizers

Based on 2694 products - Last update on the Jun 26, 2025

Heat stabilizers are typically presented as fine powders or liquids, often with a neutral color. They function by preventing the degradation of polymers when exposed to high temperatures during processing and end-use. Key features include their ability to enhance thermal stability, improve the longevity of the final product, and maintain the material's mechanical properties. Used in the automotive, construction, and electrical industries.

A notable trend is the shift towards environmentally friendly and non-toxic formulations, driven by regulatory pressures and sustainability goals. Sub-types include metal soaps, organotin compounds, and organic phosphites.

BRUGGOLEN® TP-H2217

by Brüggemann

BRUGGOLEN® TP-H2217 by Brüggemann is a halogen- and metal-free, heat stabilizer. It is used for the stabilization of aliphatic polyamides against thermal aging in unfilled and glass-reinforced polyamides. This additive offers no corrosion or electro corrosion, excellent dispersion, easy handling and accurate dosing. It displays long retention of mechanical performance of HF-FR polyamides. The addition to the polymer melt is best done by compounding on twin screw extrusion machines. It is especially suited for E&E applications at elevated temperatures (CTI 600V). The level of addition of BRUGGOLEN® TP-H2217 is 3.0-6.0%, depending on the desired properties of the finished parts. The shelf life of this product is 12 months.

BRUGGOLEN® H161

by Brüggemann

BRUGGOLEN® H161 by Brüggemann is a synergistic mixture of sterically hindered phenolic antioxidants and phosphonates in powder form. Acts as a non-discoloring antioxidant and heat stabilizer. Provides excellent protection against embrittlement and premature fatigue of the mechanical properties of the finished parts under long term stress, both in unreinforced and glass-fiber reinforced or mineral-filled polymers. Offers long term heat stability in applications up to 150°C, efficient process stabilization against yellowing and degradation, low volatility during processing, excellent compatibility, low extractability, high efficiency especially in glass-fiber reinforced or mineral-filled polyamides, complete dispersion, giving clear transparent films and fibers, no deposits (‘plate-out’) in fiber spinning. BRUGGOLEN® H161 is compatible with polyamides (PA6, PA6.6, PA11, PA12, PA copolymers), but also in other thermoplastics such as polyesters (PET, PBT), polycarbonates (PC) and their blends, styrenics (PS, ABS, SAN) and polypropylene (PP). It can be processed using extrusion, injection molding and dry-blending. Recommended dosage is about 0.2-1.0%, depending on the polymer and the desired properties of the finished parts. It has a shelf life of at least 12 months.

BRUGGOLEN® H164

by Brüggemann

BRUGGOLEN® H164 by Brüggemann is a non-discoloring antioxidant and heat stabilizer. It is a synergistic mixture of sterically hindered phenolic antioxidants and phosphonates in powder form. Provides long term heat stability in applications up to 150°C, efficient process stabilization against yellowing and degradation. Exhibits low volatility during processing, no deposits (‘plate-out’) on the finished parts after conditioning, excellent compatibility and low extractability. It offers long term protection of bright colored polymers against yellowing, excellent protection against embrittlement and premature fatigue of the mechanical properties of the finished parts under long term stress, both in unreinforced and glass-fiber reinforced or mineral-filled polymers. BRUGGOLEN® H164 is compatible with all polyamides (PA6, PA6.6, PA11, PA12, PA–Copolymers). It can be processed using extrusion, dry blending and injection molding. Recommended dosage is 0.2-0.8%, depending on the polyamide and the desired properties of the finished parts. Shelf life of BRUGGOLEN® H164 is at least 12 months.
