How is Zylon manufactured?
Zylon is made by mixing a polymer called PBO (para-phenylene benzobisoxazole), while forcing it through a spinning machine. Zylon is also used as a heat-resistant industrial material, and in the manufacture of optical fiber cables.
How is PBO polymer made?
PBO is synthesized by condensation polymerization of 4,6-diamino-1,3- benzenedoldihydrochloride (DABCO) with terephthalic acid (TA) at 60-80°c. 7. P B O fiber is the next generation super fiber with strength and modulus almost doubles that of p-Aramid fiber.

What is made of Zylon?
You can find Zylon in bike tires, tennis, badminton, and table tennis rackets, bow strings, snowboards, yacht ropes, bike spokes, and even racing cars. Discontinued Body Armor: Zylon used to be utilized as a ballistics-protective material in body armor.
Is Zylon real?
Zylon (IUPAC name: poly(p-phenylene-2,6-benzobisoxazole)) is a trademarked name for a range of thermoset liquid-crystalline polyoxazole. This synthetic polymer material was invented and developed by SRI International in the 1980s and manufactured by Toyobo. In generic usage, the fiber is referred to as PBO.
Who makes Zylon?
Zylon was developed by SRI International, and has been continually produced by Toyoba since the ’80s. This fiber features a unique chemical bond that creates its impressive strength. In fact, Toyoba boasts that a single 1.5 mm fiber strand has sufficient tensile strength to hold the weight of a small car!
How are synthetic polymers made?
Synthetic polymers are produced by chemical reactions, termed “polymerizations.” Polymerizations occur in varied forms–far too many to examine here–but such reactions consist of the repetitive chemical bonding of individual molecules, or monomers. Co-polymers can be formed using two or more different monomers.
What products are made from polymers?
Product made from polymers are all around us: clothing made from synthetic fibers, polyethylene cups, fiberglass, nylon bearings, plastic bags, polymer-based paints, epoxy glue, polyurethane foam cushion, silicone heart valves, and Teflon-coated cookware.
