Tempering furnace aramid roller rope is a kind of glass tempering furnace roller winding product, specially manufactured and woven from DuPont's original Kevlar fiber, which strength is five times that of steel of the same quality, but its density is only one-fifth that of steel (kevlar density is 1.44 grams per cubic centimeter, and steel density is 7.859 grams per cubic centimeter. Kevlar products are tough and wear-resistant, rigid and flexible, and have the special ability to penetrate the knife.
Aramid roller rope’s outstanding characteristic is high temperature resistance and long-term high temperature resistance 330 ℃, short-term high temperature resistance up to 580 ℃, and the strength is much higher than the glass fiber roller rope, so it is more suitable for glass tempering furnace roller winding.
Mainly used in tempered glass furnaces, furnace industrial ropes, tempered glass interlayers, drying equipment high temperature ropes, high temperature track ropes, fireproof track ropes, O-type transmission tapes, high temperature casing belts, chemical resistant high temperature ropes, puncture Abrasion-resistant aramid round rope, square rope, flat rope thickened aramid webbing.
2. Main Features:
Aramid fiber rope features and performance
1. Permanent heat resistance and flame retardancy, the limit oxygen index Loi is greater than 28.
2. Permanent antistatic.
3. Permanent resistance to acid and alkali and organic solvents.
4. High strength, high wear resistance and high tear resistance.
5. No molten droplets are generated in case of fire, and no toxic gas is generated.
6. The cloth surface is thickened when it is burnt on fire, which enhances the sealing performance and does not crack.

Low specific gravity
The product has a density of only 1.36g/cm3 and is lightweight and easy to transport and replace.
The product has a low elongation of only 3.6% and is not easily deformed during long-term use.
Low thermal expansion coefficient
When the product is exposed to hot objects, the product will not be deformed due to sudden high temperature, which will affect normal use.
The product is made of Kevlar fiber and has high strength, wear resistance and high temperature resistance.
High temperature resistance, flame resistance
The product has high temperature resistance, long-term high temperature resistance up to 330 ° C, short-term high temperature resistance is up to 600 ° C Degree, fire retardant does not support combustion.
High chemical resistance, high stability, and resistance to creep
The product is chemically stable. When it is attacked by strong acid and alkali materials, it will not produce large performance changes.
It is used normally in harsh environments, so it has a long service life and does not need to be replaced frequently.
The product is non-conductive and electrically insulated, making the product safer during use and isolating the risk of electric shock.
