AP-NYLON® Additives

L. Brügge­mann GmbH & Co. KG is one of the world's leading providers of raw mater­ials for the produc­tion of cast poly­amide. Cata­lysts, activ­ators, and option­ally other addit­ives for impact-resist­ance modi­fic­a­tion or heat stabil­iz­a­tion can be selected from our port­folio of the BRUGGOLEN® C series and NYRIM® series. We are glad to share our product know-how with our customers. Moreover, we rely on intensive research and devel­op­ment in the area of anionic poly­mer­iz­a­tion. AP-NYLON® addit­ives make a key contri­bu­tion to obtaining a struc­tur­ally improved poly­amide with high impact strength and a long service life. With these advant­ageous char­ac­ter­istics, AP-NYLON® cast poly­amide consist­ently opens up new applic­a­tions. Our “Rough & Tough” material is ideal for use in the trans­port sector, for indus­trial facil­ities, in resid­en­tial and road construc­tion, in safety, and in mining. Typical products of cast poly­amide extend from large, low-tension semi-finished products, such as bars, tubes, and plates, to complex, often thick-walled molded parts that cannot be manu­fac­tured through injec­tion molding or extru­sion.


The palette of BRUGGOLEN® C addit­ives includes cata­lysts and activ­ators, custom-tailored for the produc­tion of high-quality cast poly­amide through anionic poly­mer­iz­a­tion. In further devel­op­ment and innov­a­tion for our product systems, we focus not only on efficacy and effi­ciency, but also on sustain­ab­ility. With other addit­ives, such as heat-aging stabil­izers and processing agents, Brügge­mann supports customers in creating versatile products. And this includes product consulting.

BRUGGOLEN® C: addit­ives for produ­cing AP-NYLON® cast poly­amide

Product Func­tion Dosing
BRUGGOLEN® C10 Highly effective cata­lyst 0,8 to 2,2 %
BRUGGOLEN® C20P Highly effective activ­ator 0,5 to 1,5 %
BRUGGOLEN® C25 Extends processing time before solid­i­fic­a­tion 0,5 to 1,5 %
BRUGGOLEN® C235 Liquid activ­ator (without N-ethyl­pyrrolidone, which is toxic to repro­duc­tion) 0,5 to 1,5 %
BRUGGOLEN® C313 Stab­il­izer for temper­at­ures up to 120°C 0,3 %
BRUGGOLEN® TP-C1608 Stab­il­izer for temper­at­ures up to 120°C 0,3 %
BRUGGOLEN® C403 Black color­a­tion < 0,1%

Liquid impact-resist­ance modi­fiers 1,5 to 25 %


Maximum impact strength, even at the icy temper­ature of -40°C: NYRIM® is a ther­mo­plastic with extremely high dimen­sional stability over a temper­ature range of -40 to 140°C – and thus ideal for extreme applic­a­tions in the “Rough and Tough” field.

NYRIM® parts can be manu­fac­tured econom­ic­ally and with a wide variety of shapes and designs. NYRIM® is an elast­omer-modi­fied AP-NYLON® with prop­er­ties that can be select­ively adjusted, through vari­ation of the elast­omer propor­tion, depending on the use of the material. Even rein­force­ment mater­ials and/or fillers, inserts, or glass mats can be poly­mer­ized into NYRIM® parts. NYRIM® 2000 consists of up to 70% capro­lactam, NYRIM® C1 cata­lyst, NYRIM® P1-30 prepolymer. Other addit­ives, such as BRUGGOLEN® C313, enable use at higher temper­at­ures.

AP-NYLON® Capro­lactam

AP-NYLON® Capro­lactam is used as the main component in the produc­tion of cast poly­amide. In addi­tion, this monomer is used in many fields as an additive, for example in manu­fac­turing adhes­ives or melamine.

Compared to standard Capro­lactam, AP-NYLON® Capro­lactam has a lower water content (<100 ppm). This is accom­panied by an optimal reac­tion and a reduced tend­ency for agglom­er­a­tion, which offers advant­ages in dosing and hand­ling. To avoid water absorp­tion and agglom­er­a­tion also in trans­port and storage, AP-NYLON® Capro­lactam is stored and trans­ported as a liquid under dry nitrogen and it is delivered as a solid in aluminum-lined sacks. Addi­tional applic­a­tion areas for AP-NYLON® Capro­lactam:

  • Impact-resist­ance modi­fier for melamine-coated chip­board
  • Blocking agent for isocy­anates
  • Process aid for poly­amide film processing
  • Cross-linking agent for urethane-poly­ester coat­ings
