Molten metals simply slide off of the extra heavy duty coating of High-Temperature Silicone Rubber on all of these products (firesleeve), providing excellent burn-through protection.
High Temperature, Heat, Flame & Fire Resistant Silicone Rubber Coated
Fiberglass (fibreglass / glassfibre) Rope
This is a high temperature rope, heat and flame resistant silicone rubber coated fiberglass, designed to be used as a seal in environments that are exposed to the hazards of high heat and occasional flame or molten metal splash, slag, sparks and contamination.

It is available completely coated or with partial rope exposed.

This high-temperature rope is most often used as a seal where a high degree of air, gas, steam, water or liquid tightness is required
High Temperature Rope: Silicone Rubber Coated Fiberglass
High Temperature Rope
Silicone Rubber Coated Fiberglass Rope
This rope is fabricated from knitted type E fiberglass (fibreglass / glassfibre) and is then coated with a high grade high-temperature silicone rubber.
Silicone Rubber Coated Fiberglass (fibreglass / glassfibre) Withstands Molten Splash & Welding Splatter.  Withstands 500°F / 260°C continuous exposure;
2200°F / 1205°C for periods up to 15 minutes and short flash excursions to 3000°F / 1650°C.
Materials that resist catching fire, burn slowly, or retard burning can be described as either "incombustible", "non-flammable", "non-combustible", "fire-resistant" or "fire-retardant".  "Self-extinguishing" materials cease burning once the flame or heat source is removed.  "Fireproof" is understood to mean that an object cannot burn, but few materials are truly fireproof. 

Most of our products fall within one or more of the above descriptions: they resist high temperature, flame, fire, molten metal splash and weld splatter very well but may melt with prolonged exposures past their designed maximum continuous operating temperature.  They can also provide OSHA, ANSI-FM & NFPA compliance and personnel protection.

Using our products to retain heat or cold within pipes, hoses, enclosures or equipment helps conserve energy and resources, and reduces operating costs.
