Description

Dahltram® I-350CF is a cost effective, high temperature use, technical resin for additive manufacturing with a maximum recommended use temperature of 204°C (400°F). It is reinforced with carbon fibre for maximum strength, stiffness, and long-term performance. Dahltram® I-350CF is ideal for applications demanding ultimate performance, rapid prototypes, functional end use parts, high temperature tooling solutions, and high temperature master molds.

Benefits

• Dahltram® I-350CF is a cost-effective solution ideal for high strength applications, rapid prototypes,
functional mock-ups, 176°C (350°F) cure systems, and much more.

• Carbon reinforcement provides higher strength, and higher temperature performance with lower creep.

• Better moisture absorption, better strength to weight, higher stiffness, and higher flexural strength than
other high temperature additive manufacturing resins.

Notes

• As-printed mechanics from samples produced by a 12.7mm nozzle, 21 x 5mm beads, and printed under
recommended extrusion and drying conditions. Results may vary based off individual hardware and
processing conditions.

• Properties are for virgin, first grade use material only. 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).
