In 2022, the biggest event worldwide could be the war between Russia and Ukraine, which still continues on. War brings blood, pains, and loss of loved one. We truly hope the war can be over soon, and people can live in peace.
This war also casts great impact on the worldwide economy. As a leading manufacturer of thermal insulation products, we have been feeling the changes happening, as more and more customers are approaching Hantai asking for silica fiber products.
Hantai, as a professional manufacturer of thermal insulation products in China, offers a wide range of silica fiber textile products, such as silica fiber sleeve, silica fiber tape, silica fiber fabric and silica fiber rope, etc., to carter for different need from customers worldwide.
With the construction of another two (2) new workshops completed, Hantai has been moving in more and more new equipments for production of sleevings, braided or knitted, made of different materials, such as fiberglass sleeve, basalt fiber sleeve, stainless steel fiber sleeve, and particularly silica fiber sleeve, which is mostly inquired by new customers lately.
We might be very familiar with fiberglass sleeve(glass fiber sleeve), what makes the difference between glass fiber sleeve and silica fiber sleeve? Please see the below chart for their chemical characteristics.
| Product | Content | Working Temperature |
| Fiberglass Sleeve | SiO2 55% -57%, CaO 12% – 25%, Al2O3 10%-17%, MgO 0-8% | 550°C |
| Silica Fiber Sleeve | SiO2 ≥ 96%, others(ZrO2、Al2O3、CrO3)＜4% | 1000°C, intermittent exposure up to 1650 °C |
With unique product features, silica fiber sleeve has been playing an important role as thermal insulation material against extreme high temperature：
- Resistance to heat and fires of extreme high temperature:
- continuous working temperature at 1000°C
- intermittent exposure up to 1650°C
- Resist to molten metal / glass splashes
*** The higher content of SiO2(≥96%)，the higher temperature it can resist.
- Minimum lineal shrinkage under extreme heat condition.
- Inert to the majority of chemical reagent
- Replacement of asbestos, non-toxicity, environmentally friendly.
- Flexible, easy to be cut with scissors.
Hantai silica fiber sleeve has been helping customers to achieve economy by means of its durability and improve safety during the operation of industry equipment.
Beside silica fiber sleeve, Hantai New Materials also offers a wide range of sleeving to cope with different high temperature:
Fiberglass sleeve, knitted or braided，is currently the most cost-effective materials for temperature under 550°C，which is widely used worldwide. Based on its specific need, it can be treated in different way to achieve desired functions, such as:
◆ Fiberglass sleeve with coating
◆ Fiberglass sleeve heated/ impregnated
Hantai has been committed to providing customers with professional thermal insulation and protection solutions. If you are interested in the above content, and would love to check more info, welcome to communicate with Hantai!
