news | 2016 DSM and Radici focus on PPA

The high performance polyamides market sector saw further expansion with new introductions at K2016 from both DSM and Radici Group. DSM’s ForTii Ace is based

on the company’s polyphthala- mide (PPA) 4T technology and is described as a “gamechang- er in metal replacement” by Konraad Dullaert, Global Business Manager for ForTii at DSM. “We are targeting ForTii Ace at die-cast metal replace- ment applications that require a high mechanical perfor- mance that stays constant even at constant-use tempera- tures as high as 150°C, as well as superior chemical stability.” Dullaert said ForTii Ace is a

new polymer with an aromatic content of more than 50%. “You can do a lot with additives but some improvements you can only do by modifying the polymer backbone,” he said. It offers a glass transition temperature of 160°C, higher than other PPAs and a least 80°C higher than PA66, according to the company. The polymer is also said to offer better heat aging performance than rival PPAs, while DSM

claims its chemical perfor- mance and mechanical performance could make it a cost competitive contender with PEEK in some applications. Dullaert said ForTii Ace pricing will be “above PPA pricing but still single digit.” Early introductions will be short glass fibre reinforced grades but the product line will eventually include filled and carbon fibre reinforced grades. DSM said the new resins will

be targeted at the automotive industry, where they will enable OEMs to replace metals in applications previously considered too challenging for polymers, such as powertrain and transmission components. “We are working with several customers,” said Dullaert. “We don’t have a commercial application yet but this will hap- pen in the next few months.” Radici Group, meanwhile,

announced its first move into the PPA sector with the introduction of Radilon Aestus T product portfolio, a family of high performance polyamides targeted at demanding automotive, E&E and plumbing applications.

The two Aestus T2 grades

The Radilon Aestus T

product portfolio includes two PPA lines – Aestus T1 and Aestus T2 - and a high temperature PA hybrid grade – Aestus T3. Two Aestus T1 grades will

be available initially, both with 45% glass reinforcement. Aestus T1 RV330RG is a black grade offering a heat deflec- tion temperature (ISO75/2 Af) of 275°C aimed at automotive cooling system applications; Aestus T1 RG450RKC is a natural grade with heat deflection temperature of 285°C aimed at plumbing and appliance parts in contact with drinking water.

feature 30% glass reinforce- ment. Aestus T2 ERV300W is a black grade with heat deflec- tion temperature of 282°C pitched at applications such as fuel connectors; Aestus T2 RV300HF is a natural grade offering a heat deflection temperature of 280°C and suitability for lead-free soldering. One Aestus T3 grade is available now, a 50% glass reinforced natural type. Radici also used K2016 to

promote the Torzen line of PA66 materials it acquired earlier this year from Invista. Radici Marketing and Sustainability Corporate Director Filippo Servalli said the company would continue to use the Torzen brand for at least the next two years. He said production of the Torzen PA66 materials continues at the former Invista plant at Born in the Nether- lands. North American production is to be transferred from Invista’s Chattanooga facility in Tennessee, which was already set to close, to Radici plants in Ohio and Mexico. ❙

Songwon invests to take TPUs global

South Korean chemicals group Songwon – best known internationally for its polymer stabiliser activities – an- nounced its first step in becoming a global player in speciality thermoplastic polyurethanes (TPUs). “We have decided to invest

in expansion of PU precursors. The new production line will be


ready in Q1 next year and will effectively double production capacity,” said Songwon CEO Maurizio Butti. “We have traditionally been a Korean player [in TPUs]. Now we aim to be global but, of course, not in the low end of the market.” Currently stabilisers, which

account for near 70% of Songwon’s sales of around


KRW654bn ($570m) is the only part of its business that is global. Butti said the decision to invest in globalisation of its TPU business is part of a long term strategy of moving to a specialty chemical company. “It is important to have other businesses,” he said. “We are very strong in polymer stabilisers but maybe too

strong to be comfortable.” Stabilisers will not be

neglected, however. “We are putting a lot of attention on one-pack systems,” said Butti, pointing to the establishment of a 7,000 tonne/y one-pack unit in Abu Dhabi and the start-up of its first one-pack facility in China in October. ❙
