Right: Bearing producer GGB is using a new lubricated POM from Lati for photovol- taic support applications
self-lubricating bearing solutions for outdoor applications. These include photovoltaic systems, a sector that has undergone a major expansion in recent years in terms of both the number and the size of the systems being installed.

are often set up in highly aggressive environments where, in addition to constant exposure to ultraviolet radiation from the sun, they also have to contend with the effects of dust, sand, high temperatures, wind and zero humidity. Good operation of a photovoltaic power station de- pends on the functioning of its solar panels, whose efficiency is maximised through the use of a solar tracker which ensures their continuous alignment with the sun. GGB provides solutions to reduce friction and optimise product design through tribological technologies. The EP15 solar bearing system solution does not need to be greased or require any other external lubricant, and consequently eliminates the need for maintenance interventions to deal with problems caused by drying or forma- tion of abrasive sludge, which, in turn, cause wear of the metal parts. The self-lubricating plastic material can withstand the wear caused by dust and sand. Furthermore, it is not weakened by solar radia- tion, and its typical properties remain stable over time. EP15 works at temperatures between −40°C and 125°C and at all levels of solar exposure and ambient humidity. GGB says bearing systems can be subjected to compres- sion forces of up to 65 MPa without suffering structural damage. The EP15 material also

complies with RoHS, ELV and WEEE standards. LNP Lubriloy N2000, from SABIC, is a new internally lubricated compound
that helps prevent buzz-squeak-rattle noise in automotive interiors. The company says that the new grade is based on an amorphous compatibi- lised olefinic blend and offers both moulded-in colour capability and paint- ability. It is free of silicone and PTFE and can replace PC/ABS in automotive applications, allowing OEMs to significantly reduce friction and stick-slip behaviour between moulded parts to limit or prevent unwanted noise. “A quiet, smooth ride is a hallmark
of automotive quality and luxury, but cabin sounds can be more noticeable in electric and hybrid vehicles due to the absence of source noise from their powertrains,” says Ed Williams, Senior Product Manager, LNP Com- pounds. “Our new LNP Lubriloy N2000 compound is highly effective at limiting buzz-squeak-rattle noise and eliminates the need for secondary applications such as felts or tapes. This latest material innovation helps our customers provide a more enjoyable driving experience for consumers.” SABIC’s lubricating technology enables the LNP
Lubriloy N2000 compound to deliver a low coefficient of friction and good wear performance in plastic parts moving over metal and plastic surfaces. When evaluated using the BSR test VDA 230-206, the company claims that the new com- pound shows a risk priority number of less than 3 versus non-modified PC/ABS materials that typically have values greater than 5. In addition to automotive interior parts – such as mirror housings and trim, cupholders, button guides and heating- ventilation-air conditioning frames – the new material can potentially be used in consumer electronics applications where reduced friction or improved wear is required.
