Fire Proof Sleeving

Fire Proof Sleeving

Fire-proof sleeving

Our industrial grade sleeving is resistant to fuels, lubricating oils, and hydraulic fluids, and this industrial grade fire sleeve insulates against energy loss in piping and hosing. It also protects employees from burns.

It's made of knitted fiberglass yarn placed in a flexible substrate which is then coated with a high-grade silicone rubber, and is also available in an aerospace grade, with the fiberglass yarn braided instead of knit for extra strength and protection.

Our industrial grade fire resistant duct tape has a high-tack adhesive that sticks to many common building materials and a broad temperature range when applying. It also functions as an acoustic barrier.

Finally, our self-fusing non-adhesive silicone Fire Jacket End Seal Wrap fire sleeve tape can be applied across a wide range of insulating, repairing and sealing applications and is typically used to wrap and cover exposed sleeve ends.

A: It's the combination of fiberglass and silicone (not to be confused with silicon). Since fiberglass is made out of spun glass fibers, it can melt, although the temperature at which that happens is very high: 2552 to 2912°F (1400 to 1600°C). Glass and fiberglass, however, cannot burn. It's normally a good thermal insulator until it reaches high temperatures, at which point it becomes an excellent conductor.

The other material, silicone, resists burning because it has very low thermal conductivity. That means that if it's exposed to heat in one spot, the heat will not spread. Like many substances that are flame- and chemical-resistant, this is due to the strength of the bonds in the molecules themselves. You probably have some silicone tools, like muffin cups or cooking utensils, in your kitchen right now.

A: It all depends on your project. If you're fire-proofing cables or wires that you cannot easily access the ends of — like they've already been installed through firewalls or bulkheads — then tape is what you need.

It also works to protect things that are not cables or wires, but still need fire-resistance, like perimeter joints, drywall, or other flat surfaces. Finally, since it's tape, you don't need a heat source to shrink it in place. Its adhesive will stick to many construction materials and surfaces.
