Santoprene provides a soft touch for automotive interiors


Exxonmobil chemical has launched a new Santoprene TpV to provide a “comfort touch” and excellent surface qualities in automotive interiors. Designated 8211-85 m350, the new grade is claimed to offer significant cost reduction opportunities in parts such as door panels, centre consoles, pillar covers, lower instrument panels and the back covers of seats. The “comfort touch”


provided by the TpV prevents the cushion-like indentation that is often associated with foamed material structures when they are pressed.


ANTI-MICRObIALS


Schulman combats bacteria


A. Schulman has expanded its range of polybatch ABAcT anti-microbial and anti- bacterial masterbatches based on silver ion additives. The new products include


anti-bacterial grades aimed at spun-bound non-woven fabrics and thin-layer applications such as Bopp film products. The company has also


introduced a new antimicro- bial masterbatch that has been successfully tested in polyethylene films, reducing the bacteria and fungus survival rate to 0.8 to 0.1%. ❙ www.aschulman.com

Santoprene m350 also offers low and stable gloss levels, low fogging and odour emissions, plus high scratch, mar and abrasion resistance. it can be processed using


two-component injection moulding or mono-sandwich moulding onto a rigid pp substrate to produce an unfoamed structure. ❙ www.santoprene.com

ENgINEERINg PLASTICS Evonik develops super tough PEEK


Vestakeep ultimate is a new polyether ether ketone (pEEK) polymer from Evonik that is claimed to provide a 25% improvement in impact strength and double the fatigue lifetime. According to Evonik, the


improved performance opens up new opportunities in highly stressed applications such as sensors or ball bearing cages for industries such as automotive and aerospace. The Vestakeep ultimate


material is also expected to be


of interest to producers of down-well equipment in the oil and gas industries. The company says the


performance gains have been achieved while retaining processibility. ❙ www.evonik.com

plastic color corporation (pcc) has launched a new non-brominated flame retardant system for poly- propylene. FlamaSol Fr is said to offer better extinguish- ing results than pcc’s previous flame retardant, despite the fact that bromine and antimony have been eliminated from the formula- tion. Target applications for FlamaSol Fr include: construction materials, such as electrical conduit, junction boxes and switch boxes; warehouse products, including shelving and pallets; personal electronic equipment, such as comput- ers, printers and TVs; plus other applications where extreme heat may cause ignition. it meets the ul94 and AnSi 4996 testing standards for plastic pallets. FlamaSol Fr is available


in standard white, black or natural masterbatches and can be custom formulated in any colour. pcc is now working on a version for pE. ❙ www.plasticscolor.com
