Solvay: First solvent recycling plant for PVC

Wednesday, March 20th, 2002

The first industrial unit to use the Vinyloop process for solvent-based recycling of PVC started operating this month. It is at the Ferrara, Italy, site of Solvay S.A. and will be able to regenerate PVC from at least 22 million lb/yr of waste plastics. The unit is operated by Vinyloop Ferrara SpA, a joint venture of four companies: SolVin Italia, Adriaplast, Tecnometal, and Vulcaflex. The waste materials processed will be primarily insulation from electric cables, at least 80% of which will be post-consumer waste.
The patented Vinyloop process was developed by Solvay’s R&D center in Brussels. The first batches of recycled PVC were produced on Feb. 4. A second Vinyloop industrial unit will start up in 2004. It will be designed to recycle PVC-coated tarpaulins and fabrics produced by Ferrari Textiles in France. Half a dozen other potential Vinyloop projects are being studied elsewhere in Europe, Canada, and Japan.

Davis-Standard: New coextrusion die design

Wednesday, March 20th, 2002

A leading supplier of protective and point-of-sale flexible packaging for the food and industrial markets, needed a new coextrusion die design to increase its competitive advantage in the high quality blown film market. Amcor selected Davis-Standard’s ProPak die technology. Davis-Standard designed a unique 400 mm ProPak die system to meet the customer’s requirements and Amcor has proved to be impressed with the performance, versatility, fast purge times and simplified maintenance of the system. The larger ProPak design provides quality and uniformity, which is vital for a company such as Amcor as they measure EVOH thickness uniformity under a microscope. The ProPak can produce films with critical layers at a 4% variation without the use of an auto gauging system. The die also features a large IBC (internal bubble cooling) access hole that pumps increased volumes of air through the die into the bubble, making it possible to attain outputs of 400 to 500 kg per hour. Davis-Standard’s WesJet air ring optimises bubble stability. The die’s spiral channel design allows for excellent distribution of a wide range of materials and the quicker purge feature makes it possible to produce more products economically. The purge time is attributed to the side-fed coathanger pre-distribution system that eliminates complications from radial feedholes and binary divider networks. Amcor also recently purchased a seven-layer ProPak die for its pilot extrusion facility in Gent, Belgium and will use the die as an advanced multi-functional tool to develop specially designed film combinations for customers.

Frankische Rohrwerke: Innovative corrugator technology

Monday, March 18th, 2002

German company, Frankische Rohrwerke presented its knowledge in the construction of corrugated pipe production lines at the K 2001 show last year. The zooming technology is already used in the corrugated series FDC 160-60 and FDC 500/800 and can now be found in the new FDC 160-48V series. The ‘zooming’ enables an infinitely variable and optimum adjustment of the corrugator to the respective mould block size needed, making the corrugated pipe production line extremely economical. This is despite the short version which has only 48 mould block pairs compared to the long version with 60 mould block pairs, with lower investment costs, the corrugator in vacuum technology has an excellent output rate. The easy and safe change-over to other pipe dimensions requires less time due to fewer mould blocks. The FDC 160-48V provides optimum conditions for the production of a broad range of pipe products. Frankische has had over 45 years of experience in perfecting the corrugator technology, from the development, to the design and construction of corrugated pipe production lines. The range of machinery offered includes, lines for the production of high-quality single and multi-layer corrugated pipes for use in household appliances, medical engineering, electric installation, protective cable covering and drainage.

Great Lakes offers a full range of brominated, non-halogen and antimony-based flame retardants, as well as antioxidants, UV stabilisers and blends.

Cincinnati Extrusion: Wood polymer competence centre

Wednesday, March 13th, 2002

The Competence Centre for Wood Extrusion established by Cincinnati Extrusion, Vienna in co-operation with Cincinnati’s partners Fasalex, JRS, TechWood and PPT as a forum for all questions concerning wood processing, enjoyed unrivalled popularity at the K 2001 exhibition. Even the participating companies were surprised by the overwhelming feedback. Due to the successful presentation at the exhibition, wood extrusion experienced a breakthrough with plans for large-scale production of fibre profiles, and as a result first orders have been placed. The Dutch company TechWood International, participating in the SMS Technology’s joint exhibition stand, finalised a large-scale order during the exhibition. Over the next five years, Industrias Vassallo Inc. of Puerto Rico, the largest plastics processor in the Caribbean, will be producing wood profiles for 50,000 hurricane-proof houses. Vasallo has acquired a licence for the production of wood profiles from the Dutch company TechWood. Moreover, both business partners agreed that TechWood will produce the initial 1,000 houses at its own production site in the Netherlands pending completion and start-up of the new Vassallo facility in Puerto Rico. TechWood, Vassallo’s license and business partner, works with renowned machine suppliers. The company uses extruders of Cincinnati’s Titan F series for its extrusion processes. These extruders are already successfully operating at TechWood’s Dutch headquarters. Conical twin-screw extruders of the Titan F series are perfectly suitable for processing materials with low apparent density which are characteristically used in wood processing. These extruders’ feed throats have specifically-designed wide openings to accommodate bulky material. They offer the additional advantage of providing a wide diameter in the screw’s feed section combined with continuous compression brought about by the conical shape. Metering zones with a low volume and small surface area reduce the friction to a minimum and thus guarantee high-quality products. Moreover, the short residence time in the Titan F extruder ensures the protection of thermally unstable natural materials. In conical extruders, residence time is halved in comparison with parallel extruders.
