Official News Release: Coex and DuPont Introduce Carbon- and Glass- Reinforced Zytel Filaments

Coex LLC, US manufacturer of the highest quality 3D printer filaments, has added two new fiber-reinforced filaments to its material portfolio in partnership with DuPont Transportation & Advanced Polymers, a global business unit of the DowDuPont Specialty Products Division.

The filaments, Zytel 3D12G30FL BK309 and Zytel 3D10C20FL BK544, developed by DuPont, were introduced in late 2018 at Formnext 2018 in Germany.  Both were developed in order to address industrial demands for stiffer and stronger materials.

“To follow these trends, our industrial customers need 3D printing materials that offer similar formulation, mechanical [properties] and chemical properties as our well-known injection molding grades,” said Ernst Poppe, New Business Development Manager at DuPont.

Zytel 3D printing filaments

The two new filaments from DuPont build upon the ultra-low shrinkage technology of existing Zytel PA polyamides made applicable to the prototyping of automotive parts to electrical components.

The Zytel 3D10C20FL BK544 is a black polyamide reinforced with 20% carbon fiber featuring a heat deflection level of >150°C, as well as resistance to most chemicals, solvents, fuels, automotive fluids and hydrolysis. Developed for lightweight components, the material is used by customers from various industries such as the automotive, electronics, and oil and gas industries.

The Zytel 3D12G30FL BK309 is a 30% glass-reinforced black polyamide which is heat-stabilized with a heat distortion temperature of >166°C. Like the carbon fiber reinforced filament, it is resistant to most chemicals, solvents, fuels, automotive fluids and hydrolysis, with use in the same industries.
