news JSW acquires SM Platek
Japan Steel Works (JSW) has acquired an 80% stake in SM Platek, a maker of twin-screw extruders based in Ansan City, South Korea. SM Platek has now
become a consolidated subsidiary of JSW and will supply its TEK twin-screw extruders as a ‘global standard model’, focusing mainly on screws of less than 100 mm diameter. Meanwhile JSW will supply its TEX series of twin-screw extruders for value-added extrusion in areas like advanced engineering plastics, reaction extrusion, dewatering and degassing. According to JSW, there
SM Platek has
supplied more than 1,000 twin-screw extruders to date
has recently been strong demand growth for compound- ing extruders and SM Platek has a strong market share in Korea, as well as exporting to Japan, South-East Asia, India, Russia and China. As of April, SMP had supplied over 1,000 extruders to 228 customers in
23 different countries. JSW makes a variety of
plastics processing machinery, including twin-screw extruders with screw diameters from 25 mm up to the world’s current largest at 443 mm. ❙

Mixed alkyl diesters named SVHCs
The European Chemical Agency has added a series of mixed alkyl diesters (EC 271-094-0, CAS 68515-51-5) as substances of very high concern (SVHC) on its candidate list for authorisation under REACH.
These substances were added because of their reproductive toxicity properties when they contain ≥0.3% dihexyl phthalate. Their main applications include plasticiz- ers and lubricants in PVC compounds, adhesives,
coatings, building materials, cables and polymer foils. The actions bring the total number of SVHCs on the candidate list to 163, with 31 subsequently included in the authorisation list. ❙

Chemtura and Tosoh announce FR deal
Chemtura and Tosoh have signed a letter of intent for the manufacture and sale of Emerald Innovation 1000 polymeric brominated flame retardants in Japan. The plan is for Tosoh to
have the exclusive right to promote and sell Chemtu- ra’s Emerald Innovation 1000 products to Japanese customers. Under the agreement, it will also be granted a licence to manufacture the flame retardants for sale in Japan. The Emerald Innovation
1000 range was developed by Chemtura’s Great Lakes Solutions business to replace decaBDE and DBDPE flame retardants in various end-use markets. These additives are being restricted and phased out in certain territories. ❙

Janssen PMP and Intertek battle bacteria
Janssen’s Preservation & Material Protection (PMP) division, which develops and formulates active substances and products for the protection of materials and food, has joined forces with Intertek, the outsourced testing and laboratory services provider, to work on the inclusion of antimicrobials into plastics. The company has its own brand of antimicrobial for

packaging applications called Sanafor. According to Janssen PMP, the use of antimicrobials in plastic products “is a rapidly developing technology and represents one of the strate- gies to reduce the growth of bacteria and fungi, such as moulds, on plastic surfaces”. Sanafor is incorporated directly into plastics for protection against microorgan-
isms in applications including ventilation pipes, hospital bed elements, agricultural film, toilet seats, textiles and food storage containers. In the current research,
Intertek produced small batches of plastics in its laboratory polymer processing facility, notably PE and PP, and added Sanafor to them. It then created test samples via film extrusion and injection
moulding and conducted various mechanical tests to determine the influence of the antimicrobial on their perfor- mance. Janssen PMP said that Intertek will continue to work with it to explore the use of Sanafor antimicrobials in other plastic materials, including polystyrene, polyesters and polyamides. ❙
