Description

Dahltram® C-250CF is a cost effective, low to medium temperature use, technical resin for additive manufacturing with a maximum recommended use temperature of 135°C (280°F). It is reinforced with carbon fiber for maximum strength, stiffness, and long-term performance. Dahltram® C-250CF is ideal for high strength applications, rapid prototypes, functional end-use parts, room temperature tooling solutions, and low to medium temperature cure tools.

Benefits

• Dahltram® C-250CF is a cost-effective solution ideal for high strength applications, rapid prototypes, functional

mock-ups, 121°C (250°F) cure systems, and much more.

• Provides higher strength, higher temperature performance and higher throughput.

• Carbon reinforcement offers greater stiffness versus glass and low warpage for predictable results.

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).
