Novum CF 05 is a 10% carbon filled PTFE resin developed for applications requiring good chemical resistance to corrosive environments alongside strong mechanical performance. With a lower carbon loading than heavier-filled grades, this resin offers lower deformation under load, higher elongation and better fatigue performance — a combination well suited to joint seals, valve seats and backup rings operating in chemically aggressive, cyclic-load conditions.

Material Data - NOVUM CF 05

ISMAT compounds Novum CF 05 with 10% carbon filler, striking a balance that gives this grade good chemical resistance to corrosive media while keeping deformation under load low. Validated through in-house testing, it offers a tensile strength of 15 MPa minimum and elongation of 120% minimum — figures that translate into better fatigue performance over repeated loading cycles compared to more heavily filled PTFE compounds.

This grade also delivers higher dielectric strength, making it a suitable choice where electrical insulation properties matter alongside mechanical and chemical performance. Its wide operating range of -200°C to +260°C covers everything from cryogenic service to high-temperature industrial use, making it a versatile fit for joint seals, backup rings, valve seats and general seals.

If your application involves corrosive media and repeated mechanical loading, Novum CF 05 offers a resin built to handle both without premature failure. Contact ISMAT to confirm compatibility with your specific operating conditions.
