❙ DSM Engineering Plastics has gained Certified Biobased Product status from the US Department of Agriculture for its EcoPaXX polyamide 4,10 resin, which has a bio-based content of around 70% due to its use of castor oil raw materials. The USDA certification covers its 150MS unfilled, Q-HG6 30% glass reinforced and Q-HGM24 glass/mineral filled grades.

news in brief Evonik back in PA12

Materials maker Evonik announced in December that the extensive repair work at its cyclododecatriene (CDT) plant at Marl in Germany is com- pleted and the authorities have cleared the facility for operation. The Marl CDT unit was

badly damaged by an explosion and fire in March last year, which caused severe problems in the supply of polyamide 12. CDT is a raw material in the

❙ Toray is to set up a new PA and PBT compounding plant at its Indonesia Toray Synthetics (ITS) subsidiary, located at Tangerang, Banten Province, Indonesia. It is investing approximately ¥600 m (€6m) in the 6,000 tonnes/ year facility, which is expected to start production in November this year. Toray says demand for engineering plastics in Indonesia is expected to grow at 9% per annum to reach 45,000 tonnes in 2020.

❙ Natureworks and Arkema group subsidiary Altuglas have established a global joint marketing agreement intended to deliver a range of bio-based polymer alloys based on PMMA from Altuglas and Natureworks’ Ingeo bioplastic. The materials will be marketed by Altuglas as Plexiglas and Altuglas Rnew and will be targeted at durable goods applications in the signage, transport and lighting sectors.


production of the engineering polymer and Evonik is a leading supplier with its Vestamid L. First shipments of Evonik’s

Vestamid PA12 resumed in January. PA 12 is widely used in the automotive industry in production of fuel lines and system components. It offers low moisture absorption and very good resistance to impact, abrasion, stress cracking and oils and solvents.

While the official investiga-

tion into the incident at Evonik’s Marl CDT plant is ongoing, the company said the cause of the explosion, which resulted in the deaths of two Evonik staff, is believed to be due to a catalyst dosing issue. The company says additional safety measures have been implemented in the restored plant to ensure this cannot recur. ❙

VW cuts metal in front ends

Volkswagen’s new Golf model features an all-polyamide front end carrier in place of the PP metal hybrid design used on its predecessor. According to BASF, which

helped develop the new component, it is one of the first all-polymeric automotive front end carrier designs. Manufac- tured by VW in-house, the part is produced in a highly reinforced Ultramid B3WG8 grade and reduces both weight and assembly time over the previous hybrid design. The new front end was

modelled using BASF’s Ultrasim software to ensure it met stiffness, vibration and

BASF helped develop this PA front end to replace a hybrid part

failure mode requirements. Particular attention was paid to hood latch failure and the performance of the crash

sensors, which deploy the airbag safety system in the event of a collision. ❙

Reifenhäuser buys US barrel maker

tures screws and barrels for extrusion and injection machines. It will continue to be managed by Dave Larson and will operate under the Reiloy Westland name. Reifenhäuser claims its

Reiloy subsidiary is the world

leader in production of highly wear resistant screws and bar- rels. It says the acquisition of Westland acknowledges the importance of the US market for the group. ❙
