Adding knitted basalt sleeve or other Exhaust pipe heat shield insulation under the hood is a great way to increase cooling and protection for your vehicle's exhaust and electrical systems. 

Exhaust pipe heat shield insulation is a very important for the exhaust pipe.

BSTFLEX is a heat shield products manufacturer, and we will introduce to you all of the exhaust pipe heat shield insulation materials.

The knitted basalt sleeve is resistant to most oils, fuels, acids, alkalis, and other fluids. When used as an exhaust heat shield in automotive applications, basalt sleeves can facilitate efficient vehicle emission control systems by retaining high temperatures as gases flow through the exhaust.

Size Range:25mm-152mm
Operating Temperature:760℃
Material:basalt fiber yarns
Highly conformable / expandable - allowing ease of assembly over awkward shapes.

Application for the knitted basalt sleeve
Exhaust / Hot Pipe Insulation.
Used in high temperature industrial applications over pipe-work and to protect hoses and cables etc.
Automotive (and static) Exhaust Insulation.
Often used as the inner layer (heat source facing) of a two layer exhaust insulation system.
Used in heavy good vehicles, buses, and certain automotive applications.
