	Zylon - Wikipedia, the free encyclopedia
		Zylon is a trademarked name for a range of thermoset polyurethane materials manufactured by the Toyobo Corporation.
		The particular subset that Zylon is derived from are the EBXL-TPU plastics.
		Zylon also gained wide use in body armor during 1998 with its introduction by Second Chance Body Armor, Inc. But protective vests constructed with zylon became controversial in late 2003 when Oceanside, CA Police Officer Tony Zeppetella's and Forest Hills, PA Police Officer Ed Limbacher's vests failed, leaving Zeppetella mortally wounded and Limbacher seriously injured.

	Company urges replacement of Zylon vests - Pittsburgh Tribune-Review
		In 2003, a bullet pierced the Zylon vest he was wearing.
		Toyobo Co., the Japanese manufacturer of Zylon, has acknowledged it loses up to 20 percent of its durability within two years of manufacture.
		The company began using Zylon in the late 1990s, describing it as a technological breakthrough.

	Second Chance Armor, Inc.
		Zylon first debuted in the body armor industry in the late 1990s as a lighter and more wearable alternative to aramid fabrics such as Kevlar®.
		In September 2003, ongoing testing of used vests containing only Zylon showed degradation problems with the fiber that potentially shortened the wearable life of the vest.
		In the course of this investigation, Second Chance’s legal counsel has retained a leading polymer chemist, formerly of Dow Chemical, to analyze the Zylon fiber used to construct the vests to see if he could identify the cause of premature aging.

		Department has been assured by provider that none of its vests contain Zylon, but officers have been instructed to check model numbers on their equipment to ensure they are wearing Zylon-free models.

	Executive Summary of the Zylon Issue - Tactical Forums
		Zylon users and OEM armor material fabricators have made no attempts to prevent similar hazardous exposure issues with humidity during their manufacturing processes.
		Zylon may be a marvelous material when used within its very well documented limitations, but it is certainly obvious that NONE of the armor manufacturers or OEM material suppliers have taken all of those limitations into consideration during their design and packaging of the material for use as body armor.
		Zylon vests of any threat level will degrade sufficiently in two years to be effectively useless against most rounds they are rated to stop.

		When Babolat introduced their Zylon 360 racquet line their objective was to broaden the appeal of Babolat racquets by offering lighter, more maneuverable versions of the successful Pure Drive and Pure Control racquets.
		Zylon is a fiber with broad application (aerospace, sail cloth, ski poles, tennis racquets) that was developed by Toyobo Company in Japan.
		According to Babolat, Zylon is lightweight and has a higher tensile strength and modulus than Graphite, providing improved frame strength and stability while retaining maneuverability.

		But the company said Zylon works well in body armor that is properly constructed, and is not to blame for any problems with Second Chance vests.

		Also, of the remaining vests that stopped all the shots fired at it, all but four were found to have “backface deformations” beyond the National Institute of Justice standard for new armor.
		The study stressed that officers with Zylon vests should continue wearing them until they can be replaced, as they still provide better protection than no vest at all.

	Tests Shoot Holes In Safety Of Zylon Fiber Police Vests: From The Tampa Tribune (Site not responding. Last check: 2007-11-06)
		Police armor using Zylon, patented by a Japanese company, became popular about a decade ago as a lighter alternative to hotter, bulkier vests.
		Many departments have stopped using Zylon vests in the past two years in light of increased safety concerns and a flurry of lawsuits against manufacturers.
		The Justice Department, which began studying Zylon vests in 2003, found in earlier tests that the material deteriorated quickly, particularly when exposed to light, heat and moisture.

	Zylon news release
		Toyobo, manufacturers of the Zylon fiber, notified us some time ago, along with all of the other vest manufacturers, that there was a serious “loss of strength” problem over a relatively short amount of time with Zylon that had been exposed to heat (104 degrees) and (80%) humidity.
		The same vests, however, have failed the exact same test when the vests had been worn in regular duty use, although not necessarily for that long a period of time; the Forest Hills, PA Officer got his vest in January of this year and it failed when he was shot at the end of June.
		What we do know is that Toyobo, the people who make Zylon, have made public substantial research data that clearly shows a rapid decline in the strength of Zylon in a relatively short amount of time when exposed to conditions that are replicated almost daily in police work.

		The findings from the department's review of 103 vests containing the fabric Zylon comes two months after the nation's largest vest maker, Second Chance Armor, urged police agencies to replace nearly 100,000 vests containing the fabric.
		The company — which two years earlier recalled 130,000 vests partly because of problems with Zylon — said the fabric could break down, weakening the vests and potentially resulting in deaths.
		Of the vests that were not penetrated in Justice's tests, 91% showed "excessive deformation," indicating that an officer with one of the vests would have been at risk of an injury, the analysis said.

		The test also showed that Zylon weakened faster when exposed to the heat and humidity generated by an officer's body during normal wear of a bullet-proof vest, according to the lawsuit.
		In a Dec. 18, 2001, memo to Richard Davis about the "Zylon Situation," which was discussed in deposition testimony, one of Second Chance's research directors at the time, Aaron Westrick, wrote that Second Chance should "immediately notify our customers of the degradation problems we are experiencing" with the vest models made with Zylon.
		Immediately recalling Zylon vests without more test data would have put other officers' lives at risk because some officers refused to wear any bullet-proof vests before the lighter-weight models made with Zylon, which had saved 38 officers, went on the market, Davis testified.

		Does this problem extend to other brands of vest because I have noticed that Galls and safariland vests also contain ZYLON but I noticed that these vests have not been withdrawn from the market like the Second Chance vests have.

		I heard, through the grapevine, that Zylon itself is OK. BUT, Second Chance didn't do enough research and development concerning its properties when saturated.
