As recycled plastics gain wider adoption, performance requirements rise, and polymer formulations become increasingly complex, the plastics compounding industry faces a critical challenge: How can manufacturers maintain consistent material performance under more demanding processing and service conditions while balancing formulation efficiency and multifunctional requirements?
From fluctuations in melt flow index (MFI) caused by repeated thermal processing and yellowing or mechanical-property deterioration in recycled polyolefins to long-term photoaging of outdoor materials and the integration of flame retardancy with stabilization technologies, material manufacturers need more than individual additives. They need a comprehensive protection strategy tailored to different degradation mechanisms and application conditions.
In response to these challenges, Chitec Technology will participate in Compounding World Expo 2026, taking place November 11–12, 2026, in Cleveland, Ohio, USA. At Booth C-1013, Chitec will showcase advanced polymer stabilization technologies and customized additive solutions.
The exhibition will focus on three key technology areas: precise control of processing-induced degradation, enhanced long-term material protection, and integration of multifunctional additive formulations. Featuring REVONOX® antioxidant technologies, Chiguard® UV stabilization technologies, the Zuran halogen-free flame retardant series, and customized 1-Pack additive solutions, Chitec will demonstrate its capabilities extending from individual additive technologies to integrated formulation design.
Every Thermal Processing Cycle Tests Material Stability
Polypropylene (PP) and polyethylene (PE) can undergo polymer degradation when exposed to heat and oxygen during processing, resulting in changes to molecular structure, unstable melt-flow behavior, and deterioration in color and mechanical properties. This challenge is particularly significant for post-consumer recycled (PCR) plastics. As materials undergo repeated thermal processing, their accumulated heat history may intensify oxidative degradation, leaving compounders to contend with MFI fluctuations, yellowing, declining mechanical performance, and increased additive consumption and costs.
Effective stabilization is not simply about adding more additives. It starts with understanding degradation mechanisms and selecting the right protection technologies.
Chitec helps customers develop more targeted formulation strategies based on processing conditions, material characteristics, and end-use requirements through antioxidants, light stabilizers, and functional additives with different mechanisms of action.
Revonox®: Multi-Layer Antioxidant Protection from Free Radicals to Hydroperoxides
Polymer oxidative degradation is not a single reaction. It involves multiple stages, including free-radical formation, oxidative chain reactions, and hydroperoxide generation. Different degradation pathways call for different stabilization approaches.
The Chitec Revonox® series offers differentiated antioxidant technologies for polymer processing stability, color protection, and oxidative degradation control, enabling more precise material protection.
Revonox® 501 | Targeted Free-Radical Control for Improved MFI Stability
In polyolefin processing, changes in melt flow index (MFI) often indicate degradation during thermal processing. For compounders, maintaining consistent flow properties is essential to reliable processing.
Revonox® 501 uses innovative Dual-Mode Lactone technology that combines carbon-centered radical scavenging with primary antioxidant functionality. By targeting free-radical reactions, it delivers excellent MFI control.
This distinctive dual-action mechanism provides a targeted stabilization option for polyolefin systems exposed to repeated thermal processing and changes in melt-flow behavior.
Revonox® 420V | Bio-Based, Phenol-Free Antioxidant Technology for Color Stability and Formulation Innovation
Material performance is determined by more than mechanical properties. Color and appearance stability are equally important indicators of product quality.
Revonox® 420V is a palm-oil-derived, bio-based, phenol-free antioxidant offering excellent color stability and gas-fading resistance.
Unlike conventional phenolic antioxidants, Revonox® 420V offers an alternative antioxidant chemistry, giving formulators greater flexibility when balancing appearance, discoloration resistance, and additive selection.
Revonox® 608 | Rapid Hydroperoxide Decomposition to Minimize Oxidative Degradation
Hydroperoxides are important intermediates in polymer oxidation. Their subsequent decomposition can generate new free radicals, perpetuating reactions that compromise material stability.
Revonox® 608 utilizes Spiro Phosphite technology to rapidly decompose hydroperoxides, helping preserve material color and physical properties.
By controlling a critical stage of oxidative degradation, REVONOX® 608 provides an effective secondary antioxidant option for polyolefin processing.
From the radical control of Revonox® 501 and color protection of 420V to the hydroperoxide decomposition of 608, Chitec brings together antioxidant technologies with different mechanisms of action to support a more comprehensive polymer stabilization strategy.
Chiguard®: Beyond UV Protection to Long-Term Material Performance
For polymers exposed to sunlight and outdoor conditions over extended periods, photoaging is more than an appearance issue: it can also affect service life and performance reliability.
UV exposure can trigger photooxidation in polymers, leading to yellowing, surface deterioration, and reduced mechanical properties. For artificial turf, agricultural films, and other outdoor polyolefin applications in particular, addressing varying exposure environments and chemical conditions is an important formulation challenge.
The Chitec Chiguard® series combines ultraviolet absorbers (UVA) and hindered amine light stabilizer (HALS) technologies to provide specialized light-stabilization options for different material systems.
Chiguard® GA403 | Broad-Spectrum UV Protection with Optical Clarity and Color Performance
When UV protection and optical performance must be achieved simultaneously, additive selection directly influences formulation flexibility.
Chiguard® GA403 provides broad-spectrum UV protection extending to 405 nm while maintaining excellent optical transparency and color performance.
Its properties make it suitable for films, molded articles, and outdoor materials, helping customers select formulations that balance UV protection with appearance requirements.
Chiguard® HALS | Targeted Weathering Protection for Demanding Environments
The stabilization requirements of outdoor materials depend on multiple factors, including exposure duration, material composition, and chemical environment. A single light-stabilization technology may not meet every application requirement.
Chitec offers N-H and N-OR hindered amine light stabilizers (HALS), including Chiguard® 228, 6060, and 161, providing high-performance light-stabilization options for demanding outdoor environments.
These technologies can be applied in polyolefins, artificial turf, agricultural films, and material systems facing challenging chemical environments, helping manufacturers select suitable light-stabilization solutions based on actual service conditions.
From UV absorption to protection against photoaging, Chiguard® offers more than individual additives: it provides stabilization technologies selected for specific materials and service conditions.
Zuran FR: Integrating Flame Retardancy into Overall Material Design
For automotive, electrical, and industrial applications, flame retardancy is an important consideration in material design. However, incorporating flame retardants also requires consideration of processing conditions, material properties, and other stabilization needs.
The Chitec Zuran FR series offers halogen-free flame retardant solutions. Depending on application requirements, flame retardants (FR), antioxidants (AO), and UV stabilizers can also be integrated into customized 1-Pack additive packages.
This integrated formulation approach allows flame retardancy to be addressed alongside processing stability and long-term weatherability as part of an overall material development strategy.
From Individual Additives to 1-Pack: Simplifying Complex Formulation Integration
As polymers evolve toward multifunctional, high-performance, and application-specific solutions, additive formulations are becoming more complex.
A polyolefin material may require protection against thermo-oxidative degradation, UV stabilization, and flame retardancy at the same time. Integrating different chemical mechanisms, selecting compatible additive combinations, and aligning them with actual processing conditions have become essential aspects of material development.
Chitec’s customized 1-Pack solutions address this challenge through integrated formulation design.
Through formulation customization, granulation, and additive integration capabilities, Chitec Technology can provide tailored additive packages combining antioxidant, UV stabilization, and flame-retardant functions for different polymer systems and end-use requirements.
