Frequently Asked Questions

Get answers to common inquiries about our materials and services.

Carbon fiber hard felt is a composite material made from polyacrylonitrile (PAN) or pitch-based fibers, carbonized and graphitized for high strength, low density, and excellent thermal insulation properties. It is widely used in aerospace, vacuum furnaces, and high-temperature industrial applications.
Unlike traditional ceramic or mineral wool insulation, carbon fiber hard felt is rigid, self-supporting, and does not shed fibers. It offers superior thermal efficiency, mechanical strength, and longer service life, especially in vacuum and high-purity environments.
Yes, we offer full customization including CNC cutting, drilling, and molding for special shapes such as cones, stepped discs, and pressure plates to meet specific furnace designs and client requirements.
Our carbon fiber insulation materials can operate continuously at temperatures up to 3000°C in inert or vacuum environments, making them ideal for high-temperature sintering, heat treatment, and crystal growth furnaces.
Yes, we ship worldwide with reliable logistics partners. Lead times vary by destination and order size. Contact us for a detailed quote and delivery schedule.
