TECASINT 2031 black

Polyimide with 40 % graphite

Starting with the base polymer TECASINT 2011, TECASINT 2031 with 40 % graphite has been developed. The plastic has high resistance to thermal ageing and improved self lubrication. This is accompanied by minimised thermal elongation for dimensionally stable components and increased creep strength.


Chemical designation
PI (Polyimide)
1,59 g/cm3
