Fatigue Crack Growth Resistance of Polypropylene Pipe Compounds Containing Post-Consumer Packaging Recyclates

Description

Post-consumer recyclates from polypropylene (PP) packaging waste will become a highly available material fraction with limited use cases. Hence, the use of these materials in other applications is encouraged. Within this research the incorporation of PP recyclates in PP pipe compounds for drainage and sewerage applications is investigated. Several commercially available PCRs were compounded together with virgin PP pipe-grade materials and tested in terms of resistance to fatigue crack growth with cracked round bar specimens. The compounds which were created with the highest performance virgin PP grade showed better performance than other virgin PP-B pipe grades. The influence of melt mass-flow rate and polyethylene cross-contamination was also investigated.
