It enables: • Increased rPET content • Reduced CO2 emissions When added to PET preforms and bottles, ColorMatrix AAzure helps to: • Improve bottle quality - Reduced preform acetaldehyde by up to 80% - Improved mechanical strength - Lightweighting • Improve processability - Reduced bottle blowouts - Reduced scrap - Improved productivity • Reduce energy consumption during bottle blowing process ColorMatrix AAzure has a slight blue tint, which is useful for off-setting yellowing often associated with the use of rPET, and has minimal impact on final product color or aesthetics.

Our broad portfolio of product technologies and services sets us apart in the EVSE market, and our range of world-class services includes: Color Technology Custom color design and special effects to meet performance and aesthetic requirements Color & Design Services Trend & color insights, and product development assistance to optimize design Regulatory Coordination Assistance with new product approvals to reduce regulatory overhead and minimize risk Field Technical Service Support for tool design, startup, and production optimization to gain manufacturing efficiencies Sustainability Focus Innovative materials and solutions to help meet sustainability goals

This achieves both ease of running continuously and reduces lost time associated with set up.

During injection molding, longer fibers align and intertwine to form an internal skeletal network, enabling a unique set of performance characteristics, including: • High strength-to-weight ratio which facilitates metal replacement to achieve weight reduction • Added stiffness and strength to carry loads while resisting creep deformation • Increased toughness to absorb impact forces without permanent damage • High cyclical fatigue endurance to resist cracking and crack propagation • Mechanical performance that is retained across a wide temperature range • Improved dimensional stability with nearly isotropic properties and low thermal expansion • Corrosion and chemical resistance Long fiber composites provide a combination of stiffness, strength, and toughness performance enhancements not available together when using other reinforcing methods, while retaining the single- step processing simplicity of injection molding.
