With the improvement of people's living standards, the development of sea and air transportation, the innovation of medical technology and the chemical industry, the market demand for low-temperature transportation has become increasingly strong, and higher requirements have also been put forward for low-temperature cold storage transportation and storage.

WH nano thermal insulation materials, asbestos-free calcium silicate thermal insulation products, soluble environmentally friendly fiber products and other products can be used in high temperature kilns for ceramic firing.

The WH Ceramic fiber textile is a major raw material with ceramic fibers. It uses glass fibers or heat-resistant steel as a reinforcing material, and ceramic fibers are spun into yarns, and different textile processes and equipment are used to make different types of products. Cable Cable Fillers can be used in Wih Ceramic fiber or flame retardant glass fiber products for high-temperature insulated wires, cable covers, which can be further facilitated to fire, and play a thermal barrier.

For high-temperature special industries such as iron and steel metallurgy, casting, and aluminum industry, high-temperature refractory materials and heat-insulating energy-saving materials are one of the indispensable auxiliary materials.
