Description

Dahltram® C-237CF is an engineering grade additive manufacturing polymer with a maximum recommended use temperature of 135°C (280°F). It is reinforced with carbon fibre for maximum strength and long term performance. Dahltram® C-237CF is UV stabilized and ideal for demanding room temperature and elevated temperature use conditions. This can include outdoor printed applications, functional components, and details requiring long term UV stability with high mechanical performance.

Benefits

• Dahltram C-237CF provides higher strength, higher temperature performance and higher throughput.
• Carbon reinforcement offers greater stiffness versus glass and low warpage for predictable results.

• UV stabilized

Notes

• As-printed mechanics are for 12.7mm nozzle, 21 x 5mm beads, and printed under recommended
extrusion and drying conditions.

• Properties are for virgin grade material. Airtech makes no claims for material and has been
reprocessed and re-extruded.

• For comprehensive thermomechanical data and processing parameters contact your Airtech
account manager.

• The maximum use temperature is dependent upon the duration at maximum temperature, and is process
specific, Airtech recommends testing prior to use.
• Shelf life unlimited when stored in original packaging at 22°C (72°F).
