TECASINT 1031 black

polyimide with 40 % graphite

Starting with the base polymer TECASINT 1011, TECASINT 1031 has been developed. This material contains 40% graphite, unlike the starting material. TECASINT 1031 has a very high resistance to thermal ageing and improved self lubrication. Its other properties include minimised thermal elongation for dimensionally stable components and increased creep strength.
