Santoprene cuts cost and weight
Chinese automotive sealing systems manufacturer Beijing Wanyuan-Henniges Sealing Systems has commenced production of automotive glass run channel sealing systems using Santoprene TPVs from ExxonMobil Chemical. The company, a joint
venture between Henniges Automotive and the China Academy of Launch Vehicle Technology, is using three grades of Santoprene – 121- 58W175, 123-52W242 and 121-73W175 – for production of the extruded sealing channels and overmoulded corner connectors. The corner moulding
process takes just one third of the time required for a thermoset EPDM. ❙

FURNITURE Stoll Giroflex opts for PP
Swedish compounder Polykemi is supplying high-performance glass-rein- forced polypropylene for the back support of Stoll Giroflex’s new 353 office chair. The selected Polyfill PPH GF- 5030HC grade contains 30% glass fibre. Polykemi says its PP
compounds are increasingly being used in components that
TRANSPORTATION Grammer selects Lexan FST
The seat back shells and side panels fitted to the latest premium line of railcar seats produced by Germany-based Grammer Railway Interior are injection moulded in Sabic’s Lexan FST PC copolymer. Intended for use in first class
compartments, the new seats meet the requirements of Europe’s upcoming CEN/TS 45445 harmoised standard for
fire safety, which will come into effect in 2015. The Lexan FST grade (FST indicates low fire, smoke and toxicity) meets the most demanding HL3 require- ment in the new standard. “Developing our new
first-class seating posed multiple challenges,” says Lothar Winhard, general managing director, Grammer Railway Interior. “But Sabic
worked with us at every step, ultimately developing the Lexan FST resin as a drop-in material solution.” The ability to mould the
Lexan FST resin in Grammer’s existing tooling kept the investment costs down, while the good flow and easy colouring meant high quality aesthetics were maintained. ❙

XT grades are highly dimen- sionally stable due to their low moisture absorption and favourable thermal expansion coefficient, which is similar to aluminium. The resins are also suitable for use over a wide range of temperatures and display good chemical resistance. ❙
