New Light-weighting Polypropylene Solutions for Electric Vehicles - Borealis/Borouge

Published on 2017-05-03. Author : SpecialChem

Light-weighting PP
Borealis and Borouge has recently announced the launch of several new polypropylene (PP) compounds in the Daplen™ family of PP thermoplastic olefin (TPO) compounds, and the Fibremod™ range of PP fiber reinforced compounds. These innovative new additions to Borealis' proven range of light-weighting solutions for interior, exterior, and under-the-bonnet (UTB) automotive parts offer even more light-weighting potential.

Design Freedom & Flexibility

Importantly, these solutions also allow for design freedom and flexibility for vehicles with hybrid or electric powertrains. While the automotive industry strives to improve the environmental performance of internal combustion engine (ICE) technology, alternative powertrains are gaining in importance. Borealis and Borouge are leveraging their polyolefins expertise to develop value-creating and innovative solutions that offer more design freedom and enable vehicular weight savings, whilst requiring no compromises when it comes to mechanical properties.

Retooling Automotive Design for the Electric Vehicle Era and Greater Sustainability

Lightweight design, including the use of robust yet lightweight materials, has become an industry imperative.
  • Light-weighting helps reduce vehicular CO2 emissions and thus plays a crucial role in enabling manufacturers to adhere to regulatory standards. 
  • Yet some experts predict that alternative powertrains, like those for electric vehicles, will gain significant market share by 2030. 
  • At the same time, an exciting new gamut of design possibilities can be realized with electric and autonomous vehicles.

Benefits of PP Compounds

Components in battery electric and fuel cell electric vehicles can be fundamentally redesigned for low-density PP compounds due to lower operating temperatures versus ICE powertrains.
  • Components such as tailgates and front end modules can be executed in mono-material PP solutions that are not only lighter weight, but are more easily recycled. 
  • And where metal and higher-cost engineering plastics were once the material of choice for structural elements, PP-based compounds can now be considered for such applications.

Nicholas Kolesch, Head of Automotive Marketing at Borealis, said:
"As we explore the new frontier of electric vehicles together with leading OEMs and their Tier 1 partners, we are committed to developing value-creating polyolefins that enable our customers to think about the material science of cars in a different way. But even more, we can see the potential for fundamentally rethinking automotive design, thanks to the wealth of PP-based solutions available today, and on the immediate horizon."

New Lightweight Fibremod and Daplen Grades for Automotive Exteriors

The proprietary Fibremod long glass fiber reinforced polypropylene (PP-LGF) technology is known for its excellent fiber impregnation and flexibility in allowing for use of various polypropylene matrices, and the production of grades in customized colors.

LGF Fibremod™ GB416LF with 40% Filler Content

With the commercial launch of LGF Fibremod™ GB416LF with 40% filler content, Borealis is further differentiating its product offer by offering a new, lighter weight solution for a full polyolefin tailgate module as a lower-density replacement solution for conventional metal or engineering polymers.
  • As a high-flow material, Fibremod GB416LF fulfils both emission requirements and mechanical performance criteria. 
  • With excellent surface aesthetics, the grade can be used for visible parts. Its sustainability is enhanced not only by its lighter weight, but by eliminating the need for one or more paint layers, or additional aesthetic parts.

Fibremod™ GD577SF

Fibremod™ GD577SF, a new short glass fiber (SGF) grade with 50% filler, is another important extension of the Fibremod portfolio.
  • In addition to its outstanding mechanical performance – even at higher temperatures – the grade also offers pleasing surface qualities for visible structural parts. 
  • As a potential replacement solution for demanding metal and polyamide (PA) applications, GD577SF is suited for a diverse range of exterior, interior and UTB applications, including full plastic front end modules, clutch and gas pedals, external mirror structures, and more.

New Lightweight Daplen Grade for Automotive Interiors

Daplen™ EE001AI

  • As a new material generation designed to serve as a "drop-in" solution, the highly pure Daplen™ EE001AI boasts excellent mechanical properties and minimal filler content. 
  • With the similar shrinkage characteristics typical of grades with higher filler content (such as PP-T15), the new Daplen EE001AI can be used in existing tool geometries. 
  • It maintains the proven Daplen characteristics of processability and robustness in large-scale series production. 
  • While it is a lightweight grade, it certainly pulls its weight when it comes to surface aesthetics, and can be used to achieve class-A surfaces free of tiger stripes and any other visible flaws typically affecting injection-molded parts. 
  • It is highly suitable for a wide range of injection configurations and tool layouts.
