Composition Zylon® PBO is a rigid-rod isotropic crystal polymer that is spun by a dry-jet wet spinning process.

Taking a savvy approach to both liquid and solid color maximizes these benefits and helps processors to stay competitive. Assuming that the choice between solid and liquid colorants is a black and white decision Why it’s a mistake: Solid and liquid colorants each have certain applications where they make the most sense in terms of coloring effects, efficiency, and results.
