PI is a thermoset that keeps its strength and heat resistance at very small dimensions. Two items: a single-layer coated tube, and a reinforced tube with braid or coil for torque control — 2 items.
The two items Linstant publishes dimensions for. They differ in structure, so the same column reads differently — single-layer wins on thinness and heat, reinforced on torque transmission.
Strong and wear resistant, and it holds up as dimensions shrink. Where more lubricity is needed a PI/PTFE composite lowers friction. The bore stays smooth while the PI layer carries the structure.
A composite that adds braid reinforcement to PI's strength and heat resistance. Burst pressure and push go up, and torque control, flexibility and strength improve with them. The layers bond tightly.
Polyimide is chosen not by material but by Construction. If thinness and heat are the goal, single layer; if torque has to reach the tip, reinforced.
PI tubing rarely ships as cut stock. Running tip forming, marker bands and bonding in one place removes an inspection step.
If the wall has to reach 0.01 mm, PI. PEEK machines and moulds and is stiffer on its own, which suits structural parts.
It is a thermoset — it decomposes rather than melts, so it keeps its shape over 350 °C continuous and up to 450 °C short term.
No. It bonds directly to nylon and TPU untreated. Etching is only needed when a PTFE liner is involved.
Stainless steel by default, nitinol on request. Pick the structure: coil, braid, or coil plus braid.
EtO, gamma, e-beam and autoclave all work. Repeat autoclaving is not recommended.
It depends on the item and size. Prototype quantities can start small — ask us.
Dimensions, material, application. Those three are enough to start. A drawing makes it faster. We reply with TDS, MSDS and MOQ together.
