FH-1 Fireproof Bag (fabric, sewing thread, zipper, edging strip, support rods)

Hello all, we would like to talk a bit more about our new product fireproof bag for esk8 and the materials we use to make it.

Fabric: Fireproof (inside and outside), dustproof, waterproof, scratch-proof.

  • The outer flame temperature of the lighter can be as high as about 200°C.
  • The temperature of the windproof lighter can be between 1300℃~1500℃
  • Acupuncture experiment, the burning temperature of ternary battery exceeds 500℃
  • Heating experiment, the combustion temperature of ternary battery is as high as 720.1℃
  • Overcharge experiment, the combustion temperature of ternary battery is 523.3℃

As a special industry, fireproof fabrics are used for special types of protection. They are roughly divided into silicone rubber coated glass fiber fabrics, basalt fiber fireproof fabrics, acrylic cotton fiber fireproof fabrics, Nomex fireproof fabrics, SM fireproof fabrics, blue glass fiber fireproof fabrics, and aluminum foil fireproof fabrics, etc.

FH-1 fireproof bag is made of silicone rubber coated glass fiber fabrics. It is a high temperature resistance, anti-corrosion, high-strength glass fiber fabric. It has anti-aging performance, good elasticity and flexibility. It is resistant to ozone, oxygen, light and weather aging, and has excellent weather resistance and longevity. Up to 10 years, it also has high insulation performance, dielectric constant 3-3.2, breakdown voltage 20-50KV/MM, calendered or impregnated with silicone rubber. It is a high-performance, multi-purpose composite material with the latest fire protection fabrics.

Fully meets the American CA117 fire protection standard and the British BS5852 fire protection standards.

American CA117 is a widely used one-time fire protection standard in the United States:
(1) The standard has been in use for 30 years. Because the standard has a greater practical value, it is planned to be promoted throughout the United States after some supplements have been completed.
(2) This standard is formulated based on actual conditions after fully studying the causes of fires, so it is more scientific. The test fire source is the cigarette simmering (smoldering) test, the imitating match ignition test, the index of the vertical burning, the butane gas burning test, and the imitating a certain amount of newspaper ignition test, which is similar to the actual foam fire scene.

British BS5852 fire protection standard:
BS5852 can be divided into two parts according to the release time-the first part released in 1979 mainly defines the test standards for No. 0 and No. 1 fire sources. At the same time, a 30-minute water immersion test must be passed before the test. -The flame retardant standard supplemented in 1990 defines the test standard for fire sources No. 2 to No. 7.

Fireproof sewing thread, fireproof zipper, fireproof straps.

FH-1 fireproof covered sewing thread, fireproof zipper, fireproof straps, all use synthetic glass fiber high temperature thread (fireproof thread), high temperature resistant high strength, ultra-fine and flexible glass fiber, processed by high-end technology.

Melting point 750℃
Boiling point 1000℃
Density 2.4~2.7g/cm3

The biggest feature of glass fiber as a reinforcing material for reinforced plastics is its high tensile strength. The tensile strength is 6.3~6.9 g/d under the standard, and 5.4~5.8 g/d in the wet state. The density is 2.54. It has good performance and has no effect on the strength when the temperature is below 750°C. It has excellent electrical insulation and is an electrical insulating material. It is also used as a heat-insulating material and fire-resistant shielding material. Generally only corroded by concentrated alkali, hydrofluoric acid and concentrated phosphoric acid.

Support rods: Supports the shape of the FH-1 fireproof bag

The support rod of the FH-1 fireproof bag is made of pure carbon fiber, which can withstand high temperatures of 1000 ℃ without burning or breaking.

Carbon fiber is a high-strength, high-modulus fiber with a carbon content of more than 90%. High temperature resistance ranks first among all chemical fibers. It is made of acrylic fiber and viscose fiber as raw materials, which are oxidized and carbonized at high temperature. It is an excellent material for manufacturing high-tech equipment such as aerospace and aviation. It has the characteristics of high temperature resistance, friction resistance, electrical conductivity, thermal conductivity and corrosion resistance. The appearance is fibrous, soft, and can be processed into various fabrics. Because of its graphite microcrystalline structure along the fiber axis Preferential orientation, so it has high strength and modulus along the fiber axis direction. Carbon fiber has a low density, so its specific strength and specific modulus are high. The main purpose of carbon fiber is to compound with resin, metal, ceramics and carbon as a reinforcing material to make advanced composite materials. Carbon fiber reinforced epoxy resin composites have the highest specific strength and specific modulus among existing engineering materials.

Its specific gravity is less than 1/4 of steel. The tensile strength of carbon fiber resin composites is generally above 3500Mpa, which is 7-9 times that of steel. The tensile modulus of elasticity is 23000-43000Mpa, which is also higher than steel. The ratio of the strength of the material to its density can reach more than 2000Mpa/(g/cm3), while the specific strength of A3 steel is only about 59Mpa/(g/cm3), and its specific modulus is also higher than that of steel. 

F1 (Formula One World Championship) racing cars, most of the body structure is made of carbon fiber materials. A big selling point of top sports cars is also the use of carbon fiber all over the body to improve aerodynamics and structural strength.

Therefor we used the best products in our Fireproof bag, to make the bag strong, fire-resistant and much more. Nobleman team was working for a long time on this project and after many prototypes and testing we refined the bag and are already selling the best an the biggest fireproof bag for electric skateboards.
