Ticona Launches State-of-the-Art Dedicated Production Line for Medical-Grade Polymers

| Ticona recently unveiled a new facility for the production of its Hostaform MT copolymer. The material is extensively used in the manufacture of drug-delivery products. |
Formulator of engineering plastics Ticona has begun production of its medical-grade Hostaform MT, a polyoxymethylene copolymer (POM), in a first-of-its-kind production facility at its Kelsterbach, Germany site. The new, compact closed-system production line comprises separate rooms as well as dedicated machines and pipelines. It was developed to ensure stringent adherence to regulatory requirements, to avoid production mix-ups, and to safeguard product purity.
The compounding, extrusion, and packaging equipment is set up on three separate floors of a modest building in cleanable rooms of about 20 m2. Everything including the electrical casings can be quickly washed or brushed down. Even the machinery itself and the pipelines leading from room to room are designed for easy individual cleaning. The packaging and shipping room at the end of the process chain accommodates logistical needs.
The computer-controlled system provides complete quality management and produces accurate documentation that facilitates traceability of the individual formulation components back to their sources. Regular quality controls are carried out at each production stage and prior to dispatch, in compliance with US FDA guidelines.
Approximately 90,000 tn of Hostaform, which is now available in some 10 grades, can be manufactured annually at the Kelsterbach plant. The site can also produce 20,000 tn of the long-glass-fibre reinforced thermoplastics, Celstran and Compel. “Ticona is a growth-oriented company,” explains president Lyndon Cole. “In the last five years, we have watched the market in drug-delivery systems grow by 18–20% per annum in Europe and North America, and we are listening to our clients’ needs.”
Purity, biocompatibility, and sterilizability head the list of specifications for medical-grade plastics. Mechanical properties, tight tolerances, low friction and wear, high creep strength, and resistance to chemical media and corrosion are also important characteristics. Metering mechanisms used in dry-powder inhalers, for example, must have absolute dimensional stability in all climates. “The toughness and rigidity of POM makes it possible to produce delivery systems that meter drugs very precisely,” explains Stefan Disch, POM product manager. Hostaform also plays a key role in the manufacture of insulin pens, ensuring dosages that are accurate to 1/1000th of a droplet.
Ticona manufactures a number of other medical-grade polymers, including Fortron, which is used to make respirator components and nonwoven filter media. The material can also replace metal in forceps and related devices. GUR PE-UHMW, an ultra-high-molecular-weight polyethylene, is used for orthopaedic implants. Vectra MT can withstand 500 or more autoclave cycles and is used in the fabrication of components for minimally invasive surgery, among other applications.
