Sustamid 6FR EN45545-2

Our material SUSTAMID 6 FR (PA6) meets the relevant requirements of rail vehicle standard DIN EN 45545-2:2013.

As an extruded semi-finished product, it allows finished parts of large dimensions to be manufactured in small quantities – such as cable clamps for rail vehicles (image). With an order book over £300k, CB Frost are the right convertor to assist with your project needs.

Importantly, our emphasis has always been on the importance of offering a comprehensive plastic machining & fabrication & workshop. Reliably, able to manufacture component parts to customers exacting requirements. Most notably, many plastic companies only machining specific Plastics. Whereas, CB Frost has a comprehensive knowledge on all types of plastics and the required methods of manufacture.


With SUSTAMID 6 FR CB Frost offers a semi-finished extruded product made of flame-retardant polyamide 6 (PA 6). This material, which meets the relevant requirements of the new European Rail Vehicle Standard DIN EN 45545-2:2013, facilitates production of large-sized machined components and component parts in small piece numbers.

With 40 percent, SUSTAMID 6 FR stands out through a very high oxygen index (LOI – Limiting Oxygen Index) and is phosphorus and halogen-free. Fire behaviour is classified in accordance with UL 94 with V0. Compared to conventional materials, such as steel (7.85 g/cm³), the low density of SUSTAMID 6 FR (1.17 g/cm³) offers unequivocal benefits regarding weight and thus construction. At the same time, the material possesses a high degree of stiffness, tensile strength as well as good sliding and wear properties with simultaneously outstanding corrosion and chemical resistance.
