    PI, that is polyimide, is the most heat resistant plastic we sell. HT stands for high temperature version, and the yellow HT grade is dimensionally stable up to 470 degrees, which is the highest figure in the whole range.

    Polyimide is amorphous and has no melting point. The HT grade has almost no moisture uptake at all, only 0.08 percent when immersed in room temperature water. It has an oxygen index of 53 percent, far above the 21 of air, and matches fire rating UL 94 V-0.

    The price for the extremely high dimensional stability is toughness: the notched impact strength is only 1.1 kJ/m², the lowest in the category. Where the temperature is the problem and the part can sit dry, the HT grade is hard to beat.

    The 250x300 mm format in yellow makes this sheet in PI HT a practical blank for both wear plates and precision parts.

    Do you have a specific application in mind? We will help you pick the right one.
