Ceramic Fiber Blanket ( Rolling Felt)

Introduction

Hengrui ceramic fiber blanket is made of special ceramic fiber through double needle-punching processing. The double needle-punching techniques improve the degree of fiber intertexture, and the performance of delamination resistance as well as tensile strength. The blanket does not contain any bonding agent and with the characteristics of stable chemical performance, resistance to the erosion of most chemicals,The physical property like refractory and insulation keep same when meet with oil,water or steam.

Hengrui ceramic fiber blanket can be cut into different sizes according to the user needs. They can also be wrapped with aluminum foil on one or both sides to meet the requirements of different industries.
