Dyneema vs Spectra

Dyneema and Spectra are both Ultra High Weight Molecular Polyethylene (UHMWPE) fibers. The Dutch company DSM produces Dyneema while Spectra is produced by DSM’s American competitor Honeywell. DSM Dyneema BV manufactures for the American market at its factory in Greenville, North Carolina while Honeywell’s factory is in Colonial Heights, Virginia. Dyneema and Spectra are both chemically identical. The only difference between the fibers comes from how they’re braided and branded.
