Fire retardant nylon PA2210 FR – UL 94 V-0

PA2210 FR PA12-based nylon containing a halogen-free flame retardant chemical. This fire-classified nylon is roughly equivalent to PA2200 material in its mechanical properties. A chemical flame retardant ingredient distinguishes PA2210 material from conventional PA2200 nylon.

General applications

UL94 / V-0 is also FAR 25.853 tested, fire rated and halogen free. Originally developed for the production of challenging end products for the aviation industry, but it is also well suited for applications requiring fire classification in the electronics and vehicle industries, as well as for components’ so-called field testing.

Examples of areas of use:

• Aviation industry
• Electronics
• Auto industry
• Railway industry

PA2210 FR in industrial 3D printing

As a special feature, when a fire breaks out, a carbon layer forms on the surface of PA2210 components, which slows down the burning. The mechanical properties required by the fire classification must be taken into account when designing parts! For example, the recommended wall thickness for pieces is 2 mm, in order to achieve the desired fire classes. Ask our experts for more information when planning your printing.

Fire-safe PA2210 nylon is printed using SLS technology (Selective Laser Sintering). SLS is a technology that adds material. The print is created from a finely divided powder, which is melted in the building chamber in layers to achieve the desired shape.

The end result of SLS technology is accurate, but the surface of the printed piece can be rough, so the pieces can be polished as a post-processing of the print.

You can find the design instructions for pieces printed with SLS technology here.

When exposed to fire the material forms a layer of carbon on its surface to retard the flames. The technical properties required by the fire classification must be complied when designing parts. Recommended wall thickness is 2 mm to achieve the classified fire rating.
