Novum CF 04 is a 35% carbon filled PTFE non-free flow molding grade resin, engineered for high load applications where mechanical strength and electrical performance both matter. Carbon filling increases load capacity and improves weldability compared to virgin PTFE, while retaining the exceptional temperature range PTFE is known for. It’s a strong choice for joint seals, valve seats and backup rings operating under demanding mechanical loads.

Material Data - NOVUM CF 04

ISMAT manufactures Novum CF 04 by compounding virgin PTFE with 35% carbon filler, producing a non-free flow molding grade resin suited for high load applications. Every batch is validated through in-house testing to confirm consistent mechanical and electrical properties. The carbon filling gives this grade a meaningful boost in load capacity compared to unfilled PTFE, along with good weldability for fabricated components.

With a Shore D hardness of 60 minimum and an operating range of -150°C to +250°C, Novum CF 04 is built to perform in both cryogenic and high-temperature conditions. Its good electrical and mechanical properties make it a versatile option for joint seals, backup rings, valve seats and general sealing applications across demanding industrial environments.

If your application requires a PTFE compound that can handle high mechanical loads without sacrificing thermal range, Novum CF 04 is worth evaluating. Get in touch with ISMAT to discuss your specific load and temperature requirements.
