Custom Machined Polyimide (PI) Parts

Polyimide is frequently used in applications where a reliable insulating material capable of continuous use at high temperatures (up to 400 model absolutely matches inline) and nearly free from creep, as well. In comparison, polyamide is an effective solution for electrical insulation in lower temperature environments.

Flexible and rigid-flex printed circuit boards with polyimide are hygroscopic – they can absorb moisture from the air under normal room conditions.

This is treated with one or two of a solution containing ammonium ions, a solution consisting halogen ions and another disposing cu.

polyimide is excellent in terms of being able to be shaped easily (flexibility), has good adhesiveness, no brittle fracture or deviation and also superior heat resistance; therefore used for the purpose of preventing cracking under which differences between thermal expansion forces originating from molded resin with respect to semiconductor chips are caused.

Polyimide resins are also expensive, amenable to moisture pick-up and polyurethane resins have notoriously short pot life while phenolic resisns lose mechanical strength upon prolonged uv exposure [38].

Polyimides are not degraded by ultraviolet radiation, suitable for outdoor use. Resistant to weather: Polyimides are also able withstand extreme heat and cold (and anything in between), so the same materials that go into jet fuel tanks will do just fine outdoors too.
