Silicone Coated Basalt Sleeve

QIAN-ZE Silicone Coated basalt sleeve is specialized in protecting wires, cables, hoses, oil lines from extreme heat conditions and electric insulation performance in a flexible way, which are widely used in iron metallurgy industry, industrial furnaces, aerospace, nuclear power, etc. The braided basalt products are the ultimate options for extreme heat conditions which is also easy to install and cut and will provide years of abrasion protection.


Good thermal insulation and fire resistant performance make QIAN-ZE basalt fiber fire sleeve, a silicone thermal insulation, withstand continuous exposure to 800℃(1472℉), providing a 540℃(1132℉) increase in temperature protection over fiberglass products.
