FAQ:
1.What is the temperature condition:
More than 1300ºC as working temperature
2 What is the service life of this ceramic fiber sleeve
The service life depends on the glass thickness, for thin glass, if the tempering furnace is single chamber, the service life is about 6-8 months; if the tempering furnace is continuous type, the service life could be 12 months; for thick glass, the service life is shorter. This sleeves is mainly used for producing automotive glass, 3.-4mm
3.How to install and attach-fixed?
When installation, you should put some glue onto the roller surface, then install the sleeves

1. What is the diameter of sleeve?

It depends on the ceramic roller diameter, we make the ceramic fiber sleeve according to the diameter of ceramic roller?

1. What is the price?

Pls provide us the sleeve diameter, so we can give you the price.

1. Delivery time:

For popular diameter, we have the stock, we can send them to you immediately, but for some non-standard diameter, we need about one week for production.
7. Shelf Life: We have a tempering furnace is single chamber.  How many hours a day is it based on 6-8 months when driving?   (The glass used in for automobiles.The thickness is 3.0~5.0mm)
12 hours per day, for 3-4mm, the service life is about 6-8 months, for 5mm, it is about 5 months.
8. Do you apply adhesive material on the entire ceramic roller and put sleeves on it, or do you apply adhesive material only on both ends of the ceramic roller?
Yes, we use adhesive material on the entire ceramic roller
9. When replacing with new sleeves, is it possible to remove easily due to adhesive material?
When the old sleeves is removed, it is easy to do, because the adhesive/glue is a kind of silicone grease. After burning, it becomes silicon dioxide. Use a razor blade to scrape off the old sleeve. After it comes down, just use sandpaper to polish off the glue on the surface. Use coarse sandpaper to wipe off the glue. This glue is easy to handle.
10. If you have video data, please send it to us.
Yes, we have, pls contact us for more details

1. Product Overview

Ceramic fiber has a series of unique advantages such as high strength, low dielectric constant and loss, high temperature resistance, low expansion coefficient, corrosion resistance, and good designability. Ceramic fiber sleeve is woven from ceramic fiber yarn and has excellent performance of ceramic fibers.
2.Product characteristics:
When used for preparing ceramic fiber composite materials, the most reliable operating temperature is ≤ 900 ºC, the continuous working temperature is 1050 ºC, and the maximum operating temperature is 1200 ºC.
Excellent heat resistance with a low coefficient of thermal expansion of 0.55 × 10-6K-1
Temperature 20 ºC, 400 ºC, 900 ºC
Specific heat capacity (J · kg -1 · k-1) 670 964 1052
Thermal conductivity (W · m-1 · k-1) 1.4 1.84 2.68
2.1. It has excellent chemical corrosion resistance. Except for hydrofluoric acid and hot phosphoric acid, any other substance has almost no effect on it, but alkaline substances are not allowed to come into contact at high temperatures to prevent crystallization.
2.2. It has good pressure resistance, but poor impact resistance.
2.3. Ceramic fibers have good wear resistance when used at room temperature, but after high-temperature treatment, the surface wetting agent is removed and the wear resistance decreases.
2.4. Ceramic fiber sleeves have good scalability.
