Vulcanized Franklin Fibre™ is a very hard, dense homogeneous material up to .093" thick, possessing a wide range of favorable properties. In its initial stage, Franklin Fibre is processed very much like a high-grade rag insulating paper, but without the addition of sizing. It is then treated with zinc chloride, which changes the structure and converts the cotton fibers into a gelatinous material. After all chemicals are leached out by progressively soaking in tanks, the fibre is placed in heated rooms until thoroughly dry. It is then steamed and flattened under heat by hydraulic presses or rolled under pressure. After this, it is run through heated rolls to bring out surface finish. Layers of fibre can be stacked and bonded under pressure providing a thicker "built-up" sheet.
Vulcanized Franklin Fibre™ tubing is moisture conditioned and then rolled under pressure to finish inside diameter and oversized outside diameter. The outside diameter is then finished, ground to size and buffer. The outside diameter can also be knurled of skived for use in filament wound finishing for fuse tube applications.
