event preview | Compounding World Asia 2015

Speakers lined up for the

second day of the Compound- ing World Asia 2015 confer- ence include (from top to bottom):

Jeremy Paton; Dr Babu

Padmanabhan; Dr Daniele

Bonacchi; Ned Bryant; Dr

Wonkyung Ra; and Dr Angelos Kyrlidis

Reinforced compounds The opening presentation on the second day of Compounding World Asia will focus on long-fi bre thermoplastic (LFT) technolo- gies and opportunities. It will be given by Jeremy Paton, who is director of Duromer Products, which is Australia’s fi rst producer of LFTs. The company has 20 years of thermo-

plastics compounding experience and started producing its own LFT grades last year as part of a major expansion of its facility. Paton will discuss the properties, production and applications of these high-performance materials that are often used to replace metals. Continuing the focus on reinforcements,

the next presentation will be on natural fi bre reinforced compounds. The talk will be given by Dr Babu Padmanabhan, the founder and managing director of Steer in India. He will discuss how compounding lines, and in particular screw confi gura- tions, can be optimised to handle these sensitive materials to improve the proper- ties of the fi nal product. Dr Padmanabhan has become a well

known fi gure in the international com- pounding industry through his entrepre- neurship and his innovative approach to machine design, which has led to several patents. Steer has worked on a wide range of projects involving renewable fi bres and fi llers with its customers in Asia and beyond.

Advances in conductive compounds The second session on the second day of the Compounding World Asia conference will focus on technologies for adding electrical and thermal conductivity to plastics. Compounding World’s regular articles on such developments always attract high levels of interest, and the conference sessions on these themes at our events in the USA and Germany have proved very popular.

Dr Daniele Bonacchi, development

scientist with Imerys Graphite & Carbon, will open the session with a paper on the important issue of carbon black selection for electrically-conductive plastics. There is growing interest in these compounds for a range of applications such as meeting electro-static


discharge (ESD), radio-frequency interference (RFI) and explosive atmosphere (ATEX) requirements.

Imerys Graphite & Carbon (previously known as Timcal) is a leading supplier of specialty grades of carbon black for conductive compounds, and Dr Bonnachi has written several well-received technical articles on their applications for Compound- ing World magazine.

Ned Bryant, senior product development engineer with the global compounder RTP, will focus on plastics compounds for

electro-magnetic interference (EMI) shielding applications. In particular, he will examine the wear characteristics of stainless steel fi bres used in such materials.

RTP is a leading producer of conductive compounds based on a variety of additive technologies. Stainless steel fi bres can be a very effective way of adding electrical conductivity to plastics, but increased wear of processing machinery components can be a concern and needs to be minimised. The fi nal presentation in the conductive compounds session will switch attention from electrically- to thermally-conductive additives. Dr Wonkyung Ra, application development engineer with Momentive Performance Materials in Japan, will discuss the benefi ts of surface treatment and mixed fi ller formulations for thermally-conductive plastics.

There is growing interest in adding

thermal conductivity to thermoplastics for a range of automotive and electrical and electronic applications such as LED lighting. Momentive is active in this market with its hexagonal boron nitride additives which signifi cantly increase thermal conductivity while maintaining the polymer’s electrical insulation properties.

Adding value After a networking lunch-break, the

second day of the Compounding World Asia conference will continue with a series of presentations on adding value to thermoplas-

tics and developing new markets.

Dr Angelos Kyrlidis, principal scientist at Cabot in the USA, will get things rolling with a talk on the exciting topic of graphene, which is being heralded as the next wonder material. It is about 200 times stronger
