Original Press Release:



Ticona Offers Five Fortron® PPS and Eight Vectra® LCP Grades for Drug Delivery, Medical Devices, Packaging



Summit, New Jersey; Kelsterbach, Germany, June 2, 2003 - Ticona, the technical polymers business of Celanese AG (NYSE: CZ), has introduced five Fortron® MT linear polyphenylene sulfide (PPS) grades and eight Vectra® MT liquid crystal polymer (LCP) grades that are excellent candidates for use in medical technology (MT) applications such as medical devices, drug packaging and delivery systems, and other healthcare applications.

Ticona MT grades comply with USP 23 Class VI for biocompatibililty with skin, blood and tissue, and Ticona maintains active Drug Master Files and Device Master Files for these grades with the U.S. Food and Drug Administration. Ticona's MT grades also meet European Directive 2002/72/EC for food contact applications and BfR standards, respectively. BfR stands for the German Federal Institute for Risk Assessment (formerly BgVV, the German Federal Institute for Consumer Health Protection and Veterinary Medicine).

Ticona's Fortron® PPS and Vectra® LCP MT resins offer drug and medical manufacturers a wide range of design and processing options. They include filled and unfilled grades for use in injection molding and extrusion processing, and grades having various flow qualities and additives that yield parts with low friction and wear, improved surface appearance, greater stiffness and other properties.

Fortron® PPS MT grades
Fortron® MT PPS grades have good dimensional stability, toughness and rigidity. They are capable of withstanding repeated sterilization and resist hydrolysis and strong disinfectants, alkalis and most other chemical media. They are used to replace metal and for precision mechanical elements in drug delivery systems, such as aerosol valves, spring elements and gears, as well as in housings and filter media, among other applications. The five Fortron® MT grades are:
o Fortron® MT 9140L4, a 40% glass fiber-reinforced grade having high hardness and rigidity.
o Fortron® MT 9140L6, a 40% glass fiber-reinforced grade having high-flow.
o Fortron® MT 9203HS, an unfilled grade with good flow for extrusion and compounding.
o Fortrons MT 9205C4, an unfilled, low melt viscosity grade, for custom compounding and extrusion.
o Fortron® MT 9320C0, an unfilled grade with high melt viscosity for extrusion.

Vectra® LCP MT grades
Vectra® LCP MT grades offer excellent strength, stiffness, creep resistance, dimensional stability and high flow in long, thin sections. They have excellent thermal and chemical resistance and withstand numerous sterilization cycles. They can replace metal in medical and dental equipment, provide for finely structured parts in drug delivery systems, and meet the needs of devices for minimally invasive surgery and other areas. The eight Vectra® MT grades are:
o Vectra® 1300MT, an unfilled film grade for medical packaging.
o Vectra® 1310MT, a glass fiber-filled grade with added stiffness.
o Vectra® 1335MT, a glass fiber-filled grade containing PTFE for lower wear and friction.
o Vectra® 1340MT, a mineral-filled grade with good flow, impact resistance and surface finish.
o Vectra® 1345MT, a grade with higher mineral content than 1340MT for improved surface appearance.
o Vectra® 1355MT, a carbon fiber-filled grade with good stiffness and electrical conductivity.
o Vectra® 2310MT, a glass fiber-filled grade with greater stiffness than 1310MT.
o Vectra® 3310MT, a glass fiber-reinforced grade having more stiffness and temperature resistance than 1310MT.
