Long fibre PPs propagate low emissions

US compounder RTP Company has expanded its very long fibre-reinforced PP (PP VLF) portfolio to include a range of low emission products. These PP VLF products satisfy Original Equipment Manufacturer (OEM) mandates to reduce the Volatile Organic Compound (VOC) levels found in thermoplastic materials specified for use in automotive interior applications, says RTP. International legislation and automotive OEMs have identified the need to reduce odour, fogging, and total VOCs to improve air quality and the safety of vehicle interiors.

The low emission PP VLF compounds are designed for structural use and provide strength, stiffness, and dimensional accuracy, with reinforcement levels of 20-50 weight%. They have been tested and authenticated by approved outside laboratories according to German Automotive Industry (VDA) test methods for odour, fogging, and total VOC emissions. According to RTP, results from VDA test methods show that the PP VLF products meet or exceed the OEM requirements in all three categories (see Figure 1).


Low emission requirements started in Europe and are quickly being adopted by OEMs around the world. “The global trend is to reduce Volatile Organic Compounds to meet increasingly tough OEM environmental standards,” explains Dave Pahl, RTP Company Automotive Market Manager. “Our challenge was to sort through the complexity of varying OEM specifications, test methods, and classifications to develop VLF compounds that meet the industry’s toughest emission requirements. RTP Company is now positioned to support our customers worldwide with low emission PP VLF solutions.”

The compounds are used in automotive interior applications such as instrument panels, door module carriers, overhead and center consoles, seating, load floors, pedal boxes, spare tyre covers and storage bins. “Some OEMs require only that ‘open air’ applications meet VOC standards, while others include covered or enclosed applications, as well,” explains Pahl. “Regardless of the OEM definitions, classifications or requirements, Tier suppliers can leverage RTP Company’s global footprint and application development expertise for low emission, structural interior solutions.”

RTP says it has strategically positioned its VLF processing capability in the Americas, Europe and Asia, near key automotive centres to support customers locally with automotive-specified compounds and short lead times.
