PP compounds for soft feel in automotive interior components
Sabic has presented a new portfolio of polypropylene compounds that deliver a soft feel combined with good scratch performance in unpainted, low-gloss automotive interior components at NPE2018. According to the manufacturer, the new Sabic PPcompounds offer luxurious haptics and finishes. At the same time, these injection moulding materials can help automotive OEMs and tiers reduce costs by as much as 50 % by avoiding secondary operations such as applying soft paint, fabric, foam or other surface coverings.
In addition to a soft tactile feel, Sabic PPcompounds provide an attractive matte surface with good scratch resistance, impact performance and low shrinkage. These materials also deliver good sound damping capability to help create a quiet cabin environment. The portfolio, which is available globally, includes several grades of short glass fibre-reinforced PP to give customers a choice of stiffness level and material density. The materials are also UV-stabilised to prevent fading and colour shift.
Possible applications include interior trims, seat and console side cladding, glove boxes, door panels and other similar interior components. The PP compounds allow efficient manufacturing in one high-volume injection moulding step. Tata Motors selected a Sabic PPcompound to mould parts for the steering column cover and speedometer cluster top for its 2017 Tiago hatchback.
