Extrusion International 3-2018

23 Extrusion International 3/2018 NewCrosslinkable and HFFR Compounds for DemandingWire & Cable Applications introduced At Wire Düsseldorf 2018, Padanaplast introduced a range of new Cogegum ® AFR and Cogegum ® GFR wire and cable compounds incorporating an advanced halogen-free flame- retardant (HFFR) technology. The new materials meet the strict requirements of EU Regulation 305/2011 for buildings Construction Products Regulation (CPR) and ISO 6722 for au- tomotive cables. Fire incidents involving halogenated plastics can have a severe impact on the health and safety of affected people as well as on the structural integrity of buildings or, for example, on the properties of metals in end-of-life vehicle recycling. There is a growing demand for materials that will effectively minimize the hazards of toxic fumes, disorienting thick smoke and corro- sivity in the case of a fire. Important provisions and standards governing these requirements include EU Regulation 305/2011 for buildings, also known as Construction Products Regulation (CPR). Padanaplast, specializing in crosslinkable polyolefin com- pounds for use in wires and cables, pipes and fittings, has developed a range of new Cogegum ® extrusion materials de- signed to eliminate these risks. At Wire 2018, Padanaplast is introducing five new CPR-com- pliant Cogegum ® HFFR grades for building & construction and two special HFFR grades targeted at applications in automo- tive. Except for one all-thermoplastic sheathing grade, all these compounds are silane crosslinkable products of the Cogegum ® GFR series based on Sioplas ® process technology. The offering is further differentiated by application specifications, such as cable construction or enhanced resistance to fire and chemi- cals. In addition to two grades for T3 (125°C) automotive insu- lation for primary wiring applications, there is also a sheathing compound (Cogegum ® GFR 380) providing enhanced flexibil- ity and resistance to mineral oils and fuels for applications in railway, marine and the chemical and oil industry. Padanaplast compounds can be processed on most common extrusion lines, and all products conform to RoHS require- ments according to EU Directive 2002/95/EC. Cooperation Extruder reliability, stable outputs and a regional presence has fostered a mutually beneficial relationship between Davis-Stan- dard and Cooper Standard in Asia. Cooper Standard, one of the world’s largest suppliers of automotive components, has been a longtime Davis-Standard customer in North America, but in 2012 this relationship expanded to include the company’s Asian-based operations. Since that time, Cooper Standard has installed over 50 Davis-Standard extruders at plants in China, India and Korea for processing a wide range of materials, but primarily thermoplastic vulcanizates (TPV) and thermoplastic elastomers (TPE) used for manufacturing automotive window and door seals. Davis-Standard (Suzhou) Plastics Packaging Machinery, Co., Ltd. has been instrumental in this process, offering regional support and service, and enabling Cooper Standard to purchase extrud- ers directly from Suzhou using Chinese currency rather than inter- national transactions with the United States. The Suzhou location has continued to expand its scope of services since opening in the fall of 2012, which has significantly impacted Davis-Standard’s ability to better serve customers in Asia. “Davis-Standard extruders have given our Asian operation great- er consistency. We’ve seen improved pressure stability, depend- able outputs and better product quality,” said Liu Weihua, Senior Manager, Process Engineering ADV Department, Cooper Stan- dard Automotive Co., Ltd. “Davis-Standard’s location in Suzhou has improved extruder delivery times, service and technical sup- port. It has definitely played a big part in Davis-Standard becom- ing our preferred extruder provider for this region.” Davis-Standard engineers proprietary TPV and TPE extruder ar- rangements for Cooper Standard with extruder sizes ranging from 32 to 100mm (1.25 to 4 inches) along with feedscrews and control systems. In addition to thermoplastic extruders, Davis- Standard has supplied an elastomer extruder complex comprised of four cold-feed rubber extruders and a five-layer profile line Padanaplast S.r.l. www.padanaplast.com (Photo: iSTOCK)
