BRUGGOLEN® C - Efficient Additives for Cast Polyamides

As a globally leading supplier of raw materials for the production of Cast Polyamide and associated additives such as catalysts, activators and impact modifiers, Brüggemann relies on intense R&D in the field of Anionic Polymerization. AP-Nylon® additives from Brüggemann are key to obtaining structurally improved polyamides of high impact toughness and durability. As a result of these advantages, AP-Nylon® cast polyamides continue to open up ever new applications.

As a “rough and tough” material, cast polyamide is the perfect choice for a broad diversity of applications in polyamide parts are produced by anionic polymerization. This 'Rough and Tough' material is an ideal choice for applications in:
  • transport / shipping
  • industrial installations / heavy-duty equipment
  • building and road construction
  • safety technology
  • mining

Typical products range from large semi-finished stock (e.g., bars, tubes and sheets) with low inherent stresses to complex castings which cannot be obtained by injection molding or extrusion.

BRUGGOLEN® additives – efficient and sustainable
The BRUGGOLEN® C range of additives comprises catalysts and activators which have been purpose-developed for the production of high-grade cast polyamides by Anionic Polymerization. In our ongoing refinement and innovation of these systems, effectiveness and efficiency are key considerations, along with our focus on sustainability. One example of this approach is BRUGGOLEN® C235, our new high-performance liquid activator.
Liquid activators can be metered volumetrically and hence, more easily in terms of process engineering than their solid counterparts. At the same time, they yield a cast polyamide of substantially superior impact resistance. However, conventional liquid activators contain solvents such as NMP (N-methyl-pyrrolidone) which are classified as reproductive toxicants today.

Product Function Characteristics
BRUGGOLEN® C additives for the production of cast polyamide
BRUGGOLEN® C10 Highly efficient catalystnt Highly efficient solid catalyst for anionic polymerization of caprolactam with quick reaction times at low temperatures.
BRUGGOLEN® C20P Highly efficient activator Highly efficient solid activator for anionic polymerization of caprolactam with quick reaction times at low temperatures.
BRUGGOLEN® C235 New, highly efficient liquid activator Highly efficient  liquid activator for anionic polymerization of caprolactam with quick reaction times at low temperatures. To our knowledge BRUGGOLEN® C235 is the only liquid activator without usage of N-Ethyl-Pyrrolidon (NEP). NEP is a substance of very high concern and limitations of its use are expected.
BRUGGOLEN® C540 Highly efficient impact modifier BRUGGOLEN® C540 improves the impact strength of anionic polymerized casted or roto-molded caprolactam.

New Developments:
  • BRUGGOLEN® C235 is a new and optimized, sustainable liquid activator for the Anionic Polymerization of Caprolactam. Containing no pyrrolidones classified as reproductive toxicants, it delivers high reactivity and increased long-term stability.
  • BRUGGOLEN® TP-C1106 is a new retarding activator system for the Anionic Polymerization of Caprolactam. It is mainly used for the casting of thin rods or bulky pieces in order to avoid pinhole issues, lunkers and voids.
  • BRUGGOLEN® TP-C1312 is a new low-viscosity impact modifier for the Anionic Polymerization of Caprolactam. It displays the same performance than commercially available polyetheramines, but for lower costs.

In addition, Brüggemann supplies a portfolio of further additives such as crystallization accelerators and processing auxiliaries to assists users in realizing a host of products – application advice included.
