Impact and elasticity modifier for polypropylene<\/strong> from Material Wizard<\/strong> \u2014 a line of POE (poly-octene-ethylene), PBE (propylene-based elastomer) and mEPDM-based impact modifiers for toughening PP homopolymer, PP copolymer and recycled rPP. It restores the flexibility and low-temperature impact strength typically lost through thermo-oxidative degradation during repeated reprocessing.<\/p>\n Regulatory context:<\/strong> EU 2030 targets \u2014 30 % recycled content in packaging; the CSRD (Corporate Sustainability Reporting Directive) obliges companies to declare their recycled percentage. This creates mass demand for recyclate formulations in which a POE modifier is a critical ingredient.<\/p>\n The rPP problem:<\/strong> after 3\u20135 reprocessing cycles PP loses 40\u201360 % of its impact strength due to thermo-oxidative degradation (chain scission, formation of C=O groups). Adding 5\u201310 % POE brings impact strength back to 60\u201380 % of virgin PP while retaining 80\u201390 % of the original modulus.<\/p>\n Cost of the solution:<\/strong> an 8 % POE addition to rPP raises the cost by ~12 % but allows the product to be positioned as “50 % PCR” (post-consumer recycled) for brands with ESG commitments. The payback is the premium price of a “green”-certified product.<\/p>\n Automotive:<\/strong> impact PP for bumper assemblies, sill trims, door panels, passenger seats; toughened PP for under-hood parts with low thermal load.<\/p>\n Packaging industry:<\/strong> impact PP for rPP food trays (meat, fish), thick-walled logistics containers, household chemical packaging.<\/p>\n Household appliances:<\/strong> impact-resistant housings of vacuum cleaners and kitchen appliances, hand-held pneumatic tools, mid-range cordless drill housings.<\/p>\n Agricultural machinery:<\/strong> irrigation system parts, sprayer housings, protective drone covers for agricultural use (with UV stabilization).<\/p>\n Industrial packaging:<\/strong> IBC containers, pallet boards, container handles and holders that withstand a 1.5 m drop.<\/p>\n ISO 179-1eA (Charpy notched @ +23 \u00b0C and -30 \u00b0C), ISO 180 (Izod), ASTM D790 (flexural modulus and strength), ISO 75-2 (HDT\/A), MFI ISO 1133 (230 \u00b0C \/ 2.16 kg), SEM microscopy to verify phase morphology (a rubber domain size of 200\u2013500 nm is optimal).<\/p>\n The values given are measured by in-house methods close to the corresponding ISO and GOST standards.
