Gravi-Tech™ Density Modified Formulations DESIGN GUIDE 2 Gravi-Tech Chapter 1. Snap fits are only recommended for certain gravities of Gravi-Tech. Land lengths of 0.50mm–0.90mm (0.020"–0.035") are typically recommended. 24 Gravi-Tech Runners Full-round runners or a modified trapezoid runner are ideal for Gravi-Tech materials.

Gravi-Tech™ BIO Bio-Based Formulations Gravi-Tech™ BIO bio-based formulations are density modified engineered polymers that contain partially bio-based resin from renewable plant sources. Gravi-Tech BIO bio-based formulations enable visual surface effects and aesthetics including metallic finish, cool touch, and color variation. KEY CHARACTERISTICS • Customized density offering a wide range of specific gravities (1.5–11 gm/cm3) • Formulated with partially bio-based resin from renewable plant sources • Broad modulus range, from very flexible to very rigid grades • Corrosion resistance that withstands oxidization for long-term use and benefit • Chemical resistance that can be adapted depending on base resin as required • Provides visual surface effects, aesthetics and cool touch • Design flexibility and processing ease • Food contact compliance available 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 partially bio-based resin from renewable plant sources • Reduces waste and supports the circular economy • Reduces carbon footprint compared to fossil feedstock alternatives • Simplifies manufacturing and lowers cost versus metal PRODUCT BULLETIN CHARACTERISTICS UNITS Gravi-Tech BIO GT5200-5077 FD Natural Gravi-Tech BIO RS5200-5001 RS FD Natural Gravi-Tech BIO RS5200-5001 RS FD Natural X1 Gravi-Tech BIO GT5200-5003 FD Black Gravi-Tech BIO GT5200-5004 FD Black Gravi-Tech BIO GT5200-5002 FD Black Base Resin Bio-based PP Bio-based PP Bio-based PP Bio-based PP Bio-based PP Bio-based PP Recycled Content/Filler g/cm Mineral Mineral Mineral Metallic Metallic Metallic Density (ISO 1183) g/ccm 1.90 2.0 2.0 2.0 2.5 3.0 AVAILABLE GRADES Copyright © 2023, Avient Corporation.
