The supplier''s first plant, in Schwarzheide, Germany, will begin commercial supply next month. Construction there began for a 2500-tonne/yr plant in 2003, but work is already ongoing to double that by 2006. Roman Eder, VP global sales, says rapid adoption of the material by rotomolders has driven some of the need for a second plant.
Cyclic PBT uses PBT as a base material, but modifies it so that its viscosity is much lower when it is polymerized. Mechanical properties are comparable to those of PBT, but the Cyclic version has about double the molecular weight, so that wear resistance and other MW-related properties are improved.
The first announced, commercial use is in plug assist for thermoforming, supplied by Emerson & Cuming. Cyclics'' officials expect to see demand from rotomolding, cast molding, composites process, coatings, and compounds. Two compounds will be commercially available from next month. Cyclics says it is especially targeting applications such as medical devices, often made in low quantities, but via injection molding due to design requirements. "Industrial designers are a target, to teach them they don''t need injection molding for everything," says John Ciovacco, chairman of the board and VP global marketing.
