PolyamidesUn polyamide est un polymère contenant des fonctions amides -C(=O)-NH- résultant d'une réaction de polycondensation entre les fonctions acide carboxylique et amine.
Selon la composition de leur chaîne squelettique, les polyamides sont classés en aliphatiques, semi-aromatiques et aromatiques. Selon le type d'unités répétitives, les polyamides peuvent être des homopolymères ou des copolymères.

| Résumé : |
Optics play an increasingly important role in plastic components. Glossy and even surfaces are decisive for an attractive appearance. With glass fiber-reinforced polyamides (PA), these requirements can usually only be achieved with an additional coating. A PA specially developed for surface design offers an alternative approach. |
| Note de contenu : |
- Improved surface quality and high stiffness
- First class uniformity despite a higher glass fiber content
- Gloss and hardness combined
- Varied range of use
- Figure : For visible components, an even, glossy surface is often desired, which is often difficult to achieve with glass fiber-reinforced PA. PA Grivory G7V from EMS now solves this problem
- Fig. 1 : Grivory G7V achieves significantly smoother surfaces at the same mold temperature than PA6 and PA66 with the same glass fiber content. This minimizes wear and tear and ensures reduced noise development
- Fig. 2 : Even as a basic variant with a glass fiber content of 40%, Grivory G7V has less warpage than PA6 and PA66 with the same glass fiber content. With specially treated X grades, warpage can be halved again
- Fig. 3 : Due to its significantly harder surface, Grivory G7V is less sensitive to scratches than conventional PA types |
