During the thermal tempering process, glass is heated by furnace at 670-715℃. Soon thereafter the glass is rapidly quenched with cool air to strengthen it. When the glass exits furnace, it is conveyed by a series of cold metal rollers. These quench rollers are spirally wrapped with our Kevlar rope or Kevlar tape, which is used as a protective buffer material, preventing the hot glass from scratching, crash and cold explosion.
