The air intake manifolds for the Volkswagen (VW) MPI 1.4L and MPI 1.6L engines of the Golf, Lavida, Jetta and Polo car models, in addition to Skoda Fabia, are made from Borouge’s PP GB306SAFC. This material is designed to completely fulfil the parts’ specification and to withstand temperatures of 120°C up to the maximum of 140°C. The parts are manufactured in China by Roechling, one of the leading international manufacturers of automotive parts.
Borouge’s GB306SAFC provides several advantages - a significantly lower cost in parts’ production, considerable weight reduction of at least 15% and a much better acoustic behaviour.
Above all, during production, GB306SAFC has proven to require 80% less water, 40% less energy and emit 70% less CO2 and NOX emissions than polyamide (PA); which together create critical and sustainable advantages to the environment.“When compared with PA, the excellent processability of GB306SAFC allows equal productivity cycle times on both the moulding and vibrational welding machinery. This new XMOD PP also exhibits excellent balance of high impact strength, stiffness and independence of humidity which is a great advantage particularly in such humid climates like China and South East Asia,” said Thomas Rothmayer, Borouge’s Head of Competence Centre for Mobility.
As the melting temperature of PP is generally lower than that of PA, the manufacturing of the manifold components is less energy intensive. “The excellent technical support from Borouge, the in-depth information provided on the material as well as the easy processing of GB306SAFC are key criteria as we work towards realising the technical advantages at a reduced system cost ,“ said Marco Barbolini Product Manager for the air intake system at Roechling Automotive.
The joint collaboration between Borouge and Roechling serves as best practice for the automotive industry as it reinforces Borouge’s ongoing commitment and mission in enhancing Value Creation through Innovation to our valued partners.
