Solidator Functional Grey Resin (R031)

Door housing

R031 Solidator Functional Gray is much stronger, stiffer and more resistant to deformation than polyamide (PA12), but still offers sufficient impact strength and flexibility for snap connections. It is also the material with the highest processing speed on the Solidator 3+. It is characterised by extreme dimensional stability in all directions. It is suitable for connectors, housing parts, brackets and especially for functional parts. It also offers high heat resistance.
