Teijin Limited announced that Teijin group companies spearheaded by Teijin Fibers Limited will increase their use of PURITY, an environmentally friendly polyester polymers containing no heavy metals, and will also license production of PURITY to environmentally-oriented companies, in domestic and international polyester market, such as synthetic fibers, PET bottles and films. Discussions with potential licensees are now in progress.
PURITY currently accounts for 10% of Teijin's polyester production in Japan. Teijin plans to use PURITY for its almost all production of textile filament by fiscal 2010, and more than 30% of its PET bottle resin products by fiscal 2008.
Teijin developed PURITY in 2001 using a special polymerization catalyst composed mainly of titanium, which eliminates heavy metals such as antimony and thereby lowers the environmental impact of end products. Teijin eventually hopes to see PURITY become a de facto industrial standard for environmentally friendly polyesters.
PURITY has the same quality and nearly the same appearance of conventional polyester, which does not mean that it looks yellow. The absence of heavy metals makes the products easy to be recycled.
PURITY, as polyester materials, does not contain hazardous elements such as chlorine, nor does it produce dioxin when burned. In addition, it offers excellent transparency and surface smoothness.
Currently there are other types of polyester polymers which also do not contain heavy metals and are being used for fibers and films, but their color looks yellow and thus usage is limited to places where the materials are not visible to users.
