With standard insulation blankets there is a possibility that an engine oil leak or hydraulic
hose burst can result in fluids seeping into the underside of the blanket, and
lodging in the insulation matt. A build up of oil in the insulation poses a significant
danger of spontaneous combustion.
Over the last several years, Firwin Corp. has been developing a special
line of insulation product, MineWrap™, aimed at overcoming the limitations of standard insulation blankets and meeting the mining industry's stringent safety requirements. Earlier designs have been improved leading to MineWrap™ Mark II and MineWrap™ Mark III.
 Both the Mark II and Mark III feature a stainless steel foil inner liner. This liner covers the insulation matt, preventing oil from an oil leak or hose burst from reaching the insulation matt material.
stainless steel inner liner
Joint Safety Seal
Keeps hydraulic oil spills away from hot engine surfaces.
Reinforced stainless steel foil
covered with a stainless steel mesh, to withstand tough mining conditions such as falling debris.
Reinforced Outer Surface: MineWrap™ Mark III replaces the outer liner with a reinforced stainless steel foil and mesh. This gives an extra measure of rigidity and allows the blanket to stand up to the wear and tear of underground mining.
Joint Safety Seal: For an added measure of safety, the Mark III features a Joint Safety Seal. Typical engine and exhaust insulation are made up of a number of blanket sections, which are manufactured to overlap one another. Although these overlaps are designed to fit snugly against one another, the possiblity exists that oil from a hydraulic hose burst could get in between the blankets and come into contact with hot engine surfaces. The Mark III Joint Safety Seals act as a barrier to these flammable oils, provding an added measure of fire safety.
