Combining injection and extrusion for new profile


Austrian company Zitta says that it has “re-invented PVC profiles” with its I-Kal system. “We wanted to combine injection-moulded parts with the extrusion process, improving the airtight joint between the profiles,” said Werner Baumgartner, sales manager at Zitta. Zitta can produce very thick


or very thin profiles with high precision inside the outer profile, including functional


WOOD-PLASTIC COMPOSITES Ineos wins rights to ARF in Europe


Ineos Compounds has acquired the rights to the exclusive production and marketing of Active Resysta Filler (ARF) in Europe, through a licence agreement with Resysta International. ARF is the key raw


material in the production of Resysta PVC compound which is used in a wide range of wood replacement applica- tions.


The Resysta ARF will be


initially made at the Ineos Compounds site in Sins, Switzerland. Jonathan Stewart, COO of Ineos Compounds, said: “This is another milestone in the ongoing strategic partnership between the two companies. We are looking forward to working with Resysta to develop this fast growing sector by having a real alternative to tropical wood.

This agreement is further evidence of our commitment to innovation in PVC compound- ing and the fast-growing wood polymer composite market.” Resysta PVC compound is a


standardised material that does not splinter or rot over time, is obtained from a renewable resource, and is fully recyclable. It can withstand the rigours of salt water, sun and wind.


Bernd Duna, CEO of


Resysta International, said: “We are currently licensing our technology across the world, and have found in Ineos the perfect partner for Europe. By manufacturing the Resysta compound locally, the products become even more environmentally friendly and more easily available.” ❙ www.ineos.com ❙ www.resysta.com


pieces such as LED light strips. It can use materials that are soft or hard, transpar- ent or coloured, and without glass fibre reinforcement, he says.


“The main difficulty was to


bond two different materials intimately without deformation by thermal effect or mechani- cal pressure,” he said. “The types of materials must have the same polarity in order to form a connection without any


additional means, like a primer or adhesive.” The process feeds the moulded parts through an extrusion die so that the film connects the parts. This allows Zitta to produce calibrated profiles as precise as +/- 0.1 mm in almost any geometric form. The firm says it can make


custom formulas in three days, and dies in 10. ❙ www.zitta.com


PLASTICISERS


Toxicology tests show PETV safety


An independent study on the toxicological properties of Perstorp’s Pevalen non- phthalate PVC plasticiser shows that it has no toxic properties and that it should be approved for food contact applications, says the company. Perstorp developed


Pevalen (PETV or pentaeryth- ritol tetravalerate) for use as a plasticiser in close-to- consumer applications in flexible PVC. It is widely used for products such as coated fabrics, but approval for use in products that may come into contact with food – such as conveyor belts in food preparation – is ongoing due to more strict testing requirements. The recent test, carried out by the Research Toxicology Centre (RTC) in Pomezia, Italy, is a key requirement for approval by the US Food and Drug Administration (FDA). The tests showed that Pevalen is non-toxic, even at the highest dosage that is required by standard protocols.


“This is the latest and most detailed study showing that Pevalen is non-toxic,” said Carina Fogelberg, product stewardship and regulatory affairs specialist at Per- storp. “We are obviously very happy with the results, and shall now move ahead to obtain full food contact approvals.” ❙ www.perstorp.com
