Repsol has developed a new grade Repsol Isplen® PF179EV, together with Grupo Antolin and 3M. This new polypropylene compound has been possible due to a close collaboration with Grupo Antolin, the biggest Spanish manufacturer of interior compounds for automobiles, and 3M, alongside Repsol’s compounds manufacturing knowledge and experience in the development of technical materials for automotive applications.

Based on the synergistic combination of traditional fillers and 3MTM Glass Bubbles, it is specially designed to obtain an important weight reduction in final parts while preserving the desired mechanical properties for these materials pieces: flexibility and scratch resistance.

The tailgate interior trim trunk door, manufactured by Grupo Antolin for new models of compact cars, has proved a significant weight reduction can be obtained with this new grade. This new material has enabled a 9.3% weight reduction in the final part, in relation to a standard 16% of talc polypropylene compound (PP 16% Talc Filled). The weight reduction is not the only leaping quality, this grade’s scratch resistance offers a significant improvement over polypropylene grades with Talc Fillers (PP-Talc), and with colour and brightness (ΔL) deviation values below 1.0 for a different surface finishes.

With this new grade, Repsol is best suited to meet the specific needs of the automotive industry, offering an adequate solution to the growing demand for vehicle weight reduction with excellent surface finish and improved mechanical properties. Similarly, Repsol is committed to its customers’ global strategy, putting its entire organisation at their disposal to achieve a common goal: to develop materials that meet the current trends, overcoming the challenges of the automotive sector and contributing to reduce vehicle emissions.
