Gravi-Tech REC recycled grades enable visual surface effects and aesthetics including metallic finish, cool touch and color variation, suitable for applications in packaging and consumer goods such as cosmetic caps and closures, perfume caps, spirit bottle caps and luxury boxes. KEY CHARACTERISTICS • Customized density offering a wide range of specific gravities (1.2–11 gm/cm3) • Based on recycled resin from PIR and PCR sources • Broad modulus range, from very flexible to very rigid grades • Corrosion resistance that withstands oxidization for long-term use and benefit • Chemical resistance can be adapted depending on base resin as required • Provides visual surface effects, aesthetics, and cool touch • Design flexibility and processing ease MARKETS AND APPLICATIONS Applications in packaging and consumer goods in which a more sustainable solution is preferred: • Cosmetic caps and closures • Perfume caps • Spirit bottle caps • Luxury boxes • Handles and knobs SUSTAINABILITY BENEFITS • Formulated with recycled resin from post-industrial recycled (PIR) and/or post-consumer recycled (PCR) sources including ocean bound plastic waste • Reduces waste and supports the circular economy • Reduces carbon footprint compared to fossil feedstock alternatives • Simplifies manufacturing and lowers costs versus metal PRODUCT BULLETIN CHARACTERISTICS UNITS Gravi-Tech REC-CI GT5200-5089 PT Natural Gravi-Tech REC GT5200-5075 Black X2 Gravi-Tech REC GT5200-5078 Gravi-Tech REC GT5200-5079 Gravi-Tech REC GT5200-5060 Gravi-Tech REC GT5200-5057 Base Resin Ocean Bound rPP rPP rPP rPP rPP rPP Recycled Content/Filler g/cm >98% PIR+PCR 60% PIR/Mineral >95% PIR/Mineral >95% PIR+PCR/Mineral 30% PIR/Mineral 30% PIR/Mineral Density (ISO 1183) g/ccm 1.2 1.2 1.2 1.2 1.9 2.0 CHARACTERISTICS UNITS Gravi-Tech REC GT7300-5034 X2 FD Natural Gravi-Tech REC GT7300-5036 Gravi-Tech REC GT7300-5025 Gravi-Tech REC GT6000-5032 GT6000-5031 Base Resin ABS rABS/ABS rABS rPA6 rPA6 Recycled Content/Filler g/cm 50% PIR/Mineral 65% PIR/Mineral 10% PIR/Mineral 20% PIR/Mineral 20% PIR/Mineral Density (ISO 1183) g/ccm 1.5 1.5 2.2 2.7 2.8 AVAILABLE GRADES Copyright © 2024, Avient Corporation.

We all know that COVID-19 has had far-reaching global health and economic consequences. Additionally, new minimum recycled content thresholds will mean that from 2025 there will be a sales ban on PET bottles containing less than 25% recycled plastics, increasing to 30% in 2030.
