Ceramic Fibre Products

Ceramic fiber is made from a mixture of silicium oxide and aluminum oxide. Both of these elements are in a very pure form, which is melted in an electric arc resistance furnace. This molten is spun into a fiber. Ceramic fiber as with other textile fibers should be processed in such a way that the amount of dust produced is kept to an absolute minimum. If the concentration is too high, the wearing of a mask is recommended. The precautionary measure is particularly advisable when processing free fibers. Because of their structure, finished textile products produce little dust.

• Good resistance to oxidizing and reducing agents
• Low thermal conductivity
• Excellent resistance to chemical products, with the exception of  hydrofluoric acid, phosphoric acid           and concentrated bases.
• No ignition loss as ceramic fiber do not contain any crystallization water
• Neither the thermal nor the physical properties are affected by water or steam

Ceramic fiber can be spun just like the other fibers. They yarn so obtained can be twisted, intertwined or woven. A small quantity of organic fibers is added to increase mechanical resistance during processing. Such support vanishes with low temperature, affecting in no way the ceramic fibers characteristics, only the mechanical resistance is decreased. Ceramic yarn with a glass core reinforced increases its mechanical strength. For a higher tensile strength requirement, ceramic yarns are reinforced either with brass, stainless steel or inc onel wires.

Style BJ7330 In Glass fiber

ceramic fibre glovesGloves made by a highly texturized fabric that withstands temperatures up to 600°C and resists most acids and alkalines.
This comfortable wool-lined glove is designed for specific industrial and safety applications such as insulation for turbine engines,
expansion joints, heat reflectors, welding blankets and asbesto
s encapsulation.

Style BJ7350 In Kevlar fiber
Kevlar fibre gloves Heat resistant glove is designed for heat resistance. Glove with a KEVLAR® fiber blend material. The work glove hasa full wool lining for added heat resistance. This glove is a very thick and large glove that is designed for heat resistance; consequently, the dexterity of the glove is extremely limited. In addition, the high temp glove is also available with a leather reinforced palm, thumb and fingers Ideal for foundries, glass blowing, and metal forging.
Dimensions: Available in several different shapes, long, short, and with five fingerless.
