TPU 95A and TPU-GF printed to order. For dampers, gaskets and grips, and, in our experience, for parts that rub against something.
TPU is the only stretchable material in our range. Where a hard part cracks at that deformation, TPU springs back. That makes it the choice for anything that has to damp, seal or grip: a shock absorber, a gasket, a handle, a protective sleeve.
There is a second, less known reason to pick it: in our experience TPU is a good choice for parts that get rubbed or scraped, for example by grit, belts or other plastic.
The flexible form: stretchable, tough and with a soft grip. The manufacturer gives no heat deflection temperature; ask us for warm applications. The choice for dampers, gaskets, grips and sleeves.
With glass fibre in it this is a stiffer, semi-flexible TPU (Shore 67D): hard and tough, with a little give, not stretchy like the 95A.
The manufacturer gives no heat deflection temperature for either, so ask us about warm applications. In our experience TPU hardens over time outdoors in the sun. If the part has to be stiff or carry a load, look at a fibre reinforced nylon or at PET-CF.
Typical work: vibration dampers and feet, gaskets and seals, protective sleeves, grip parts, and parts that gave up too fast in a hard material.
On a flexible part the wall thickness and the infill count for as much as the material: the same shape can come out soft or nearly firm. So tell us how hard it should feel. If you would like to send the part to be replaced, first ask through the contact form whether that is possible, and tell us what it is worth.
