Fiberglass yarn can possess high strength and resistance to heat and chemicals.
One may argue that fiberglass, a silica based material, is a natural fiber, but fiberglass must be highly processed before it can be useful as a yarn. Fiberglass is very brittle and difficult to work with. It does not absorb water and has very low elongation.
Fiberglass yarn offers:
- High strength (when the fibers are in an oriented direction)
- Heat resistant
- Chemical resistant
- High (2.48 to 2.54 g/cc) densities
