Product features:Fulai modified heat preservation cylinder is a high-quality solidified graphite felt made of the high-performance modified graphite soft felt developed by our company as the base material. It has better heat preservation performance, less particles, high density, high strength, high oxidation resistance (long life) and other outstanding features.

As a way to reduce particle emission at high temperature, we provide users with a variety of surface treatment options for curing felt:

✧ ISO, OS coating (OS is water-soluble coating imported from Germany)

✧ Pyrocarbon CVD coating

✧ Carbon cloth, graphene paper cover

We have perfect production process and equipment, can customize products of various sizes and shapes according to the needs of users, so as to meet your needs for various vacuum and high temperature furnace thermal insulation materials.
