PI, that is polyimide, is the most heat resistant plastic we sell. This grade is built on a high temperature base, HT stands for the high temperature version, and it also has graphite blended in, 15 percent, which lubricates dry.

This is the driest grade in the catalog and one of the stiffest in tension. The tensile strength sits at 93 MPa. The material has no melting point and matches fire rating UL 94 V-0.

The price for the stiffness is toughness: the graphite filled grades crack rather than bend. And like all PI it is sensitive to hydrolysis, that is hot water and steam. Where it is dry, hot and the surface has to slide it is in a class of its own.

This round rod in PI HT GR15 is 500 mm long and gray, a turning blank for bushings, spacers and insulators in hot environments.

This round rod in PI HT GR15 is gray and measures 500 mm, which makes it a specific solution in the range.

With the dimensions 500 mm the round rod in PI HT GR15 works particularly well where the properties of the material come into their own.
