Extensive Product Line Breadth

Solvay Polymer Additives offers the plastics industry a range of technically superior stabilization solutions tailored to meet market-specific application needs. Leveraging our expansive portfolio, industry knowledge and applications expertise, we help customers worldwide achieve their most challenging production goals. Our portfolio includes:

CYASORB CYXTRA® - V series

As our latest technology platform for improved polymer stabilization, CYASORB CYXTRA® is a series of UV stabilizers devised to take protection a step further. Our V series stabilizers provide manufacturers with the optimal balance of processing and cost efficiency while delivering a high degree of performance durability to polyolefins in interior and exterior automotive parts. 

CYASORB CYNERGY SOLUTIONS® 

CYASORB CYNERGY SOLUTIONS® high-performance light stabilizers are designed to meet requirements of an array of specific plastics and coatings applications with the use of innovative technology and experienced, in-depth market expertise. 

Our A series stabilizers for agricultural markets offer enhanced protection against weathering, such as sunlight, wind, precipitation and agrochemical exposure for polyethylene mulch film and greenhouse films, tunnels, shade clothes and shrouds. 

For the building and construction market, our B series stabilizers provide exceptional long-term UV and thermal protection for polyolefins used in outdoor construction applications, such as siding, decking, roofing membrane, tiles and shingles. 

In thicker polyolefins and blow molding applications—including crates, boxes, drums, industrial containers, toys, trash bins and rollout carts—Solvay’s M series of light stabilizers displays high UV protection at half the dosage of commercial HALS, delivering outstanding formulation flexibility. 

Our R series offers a range of superior stabilization for rotomolded PE and PP polyolefin parts, including outdoor toys, slides, kayaks, water tanks and fuel tanks. These high-performance light stabilizers enable a broad processing window, exceptionally low part color contribution and reduced energy costs. 

The L series of stabilizers provides outstanding UV protection in coatings applications, such as top, clear and base coats, 1K and 2K systems, and plastic or metal substrates. 

CYASORB THT®

CYASORB THT® family of light stabilizers delivers exceptional UV stabilization performance combined with thermal protection for particularly demanding applications and markets. 

CYANOX®

CYANOX® high-performance antioxidants protect durable polyolefins against oxidative degradation by minimizing physical property changes during thermal processing, such as extrusion, compounding, or injection molding, blow molding and rotational molding. 

CYASTAT®

CYASTAT® superior antistatic agents prevent the buildup of static charges in a variety of plastics and coatings applications.

Unrivaled Performance

Our range of high-performance UV stabilizers, antioxidants and antistatic agents is specially designed to extend service life and maintain the appearance of polymer products in market-specific applications. UV stabilizers, such as our CYASORB CYXTRA® and CYASORB CYNERGY SOLUTIONS® series, protect surface finish, aesthetics and critical physical properties necessary for long-term performance despite extensive exposure to harsh conditions, such as weathering, excessive sunlight, heat and humidity. These innovative products are formulated with specific market needs in mind to provide cost-effective solutions with superior performance.
 

Improved Longevity and Recyclability for a Circular Plastics Economy  

As plastic continues to hold a critical role in our daily lives, the industry is a user of nonrenewable resources and leaves a significant impact on the environment. Determined to contribute to the global transition to a circular economy, Solvay remains dedicated to developing sustainable solutions that positively impact our partners and the full value chain. 

Our polymer additives, namely light stabilizers and antioxidants, improve the durability and quality of recycled polyolefin plastics. Solvay aims to facilitate the upcycling of recycled feedstock in high-value end markets. Additionally, our stabilizers are strategically designed to support lightweighting trends, reduce CO2 emissions, and improve crop yield, benefitting sustainability goals across the automotive, construction and agriculture industries, respectively.  
 

Commitment to Capacity Expansion

To address market demand for light stabilizers, Solvay Polymer Additives continues to invest in infrastructure and application knowledge, as well as in our supply chain, to remain agile and adapt to changing dynamics. In 2020, Solvay’s new high molecular weight (HMW) hindered amine light stabilizer (HALS) unit went online. This state-of-the-art facility is specifically designed with cutting-edge technology to ensure operational safety, mitigate environmental impact, and improve the quality and consistency of our HALS solutions. 

 

Continuous Innovation

As market applications for plastics continue to evolve, so do consumer demands and industry requirements. Our advanced light stabilizers play a critical role in the creation of new markets and applications for plastics. Solvay remains the frontrunner in developing innovative chemical solutions to address emerging needs. For example, we help the automotive industry adhere to new emission standards, facilitate compliance with Worldwide Harmonized Light Vehicle Test Procedures (WLTP), support lightweighting requirements and develop products designed with low volatile organic compounds (VOC) emissions in mind.
