Sheet in PI Ast 750x300 mm brown

PI, that is polyimide, is the most heat resistant plastic we sell. Ast stands for antistatic, meaning it does not build up a charge. This grade is also glass fiber reinforced, which gives it the highest tensile modulus in the whole PI category.

Polyimide is amorphous and has no melting point. The tensile modulus is 7000 MPa and Shore D sits at 93, which is the highest of the PI grades. The tensile strength is 93 MPa and the elongation at break 1.5 percent. The material matches fire rating UL 94 V-0.

The surface resistivity sits in the ESD range and carries static charge away. The weakness is hydrolysis, that is hot water and steam. Where static electricity is the problem and the part is to sit dry, the Ast grade is the right choice.

The sheet in PI Ast measures 750x300 mm and is supplied in brown. A practical sheet for you who are going to mill or saw out parts in polyimide.
