Celanese · Fortron 1140L4
Fortron 1140L4 is a polyphenylene sulfide with 40 percent glass fibre and one of the most widely used PPS grades available. It combines a high continuous service temperature with inherent flame retardancy and very good chemical resistance.
Rated 1 to 5 relative to the other materials in our range. This is an experience-based orientation aid, not a measured value – the hard numbers are in the table below.

These values are taken from the manufacturer datasheet and apply to the material, not to the printed part. In 3D printing the achievable properties depend on part orientation, layer height and process parameters – in the Z direction in particular they are lower. Please talk to us before relying on them for design.
“Qualified for functional parts” is a general classification. A functional part can be a simple clip or a main load-bearing member – the forces and load cases differ fundamentally. We therefore always assess in each individual case whether a material is suitable for your part.
