Additives Enhance Outdoor Plastics Durability and Stability

At Chinaplas 2026, held from April 21 to 24 at the National Exhibition and Convention Center in Shanghai, BASF is showcasing plastic additive technologies designed to improve durability and performance in outdoor, agricultural, and industrial applications. The solutions address increasing requirements for weather resistance, material longevity, and sustainability across the plastics lifecycle.

Light Stabilization for Outdoor Applications
Outdoor plastics are exposed to continuous environmental stress, including UV radiation, heat, humidity, and chemical exposure. BASF’s Tinuvin NOR 600 additive is engineered to enhance long-term weatherability and acid resistance in materials such as PVC, PVC alloys, and polyolefins.

The stabilizer operates synergistically with other light stabilization systems to improve resistance to UV-induced degradation and thermal aging. This is particularly relevant for applications such as roofing membranes, truck tarpaulins, and artificial turf, where prolonged exposure to harsh conditions can lead to material failure.

The formulation is supplied in a low-dust, free-flowing form, supporting safer handling and consistent processing in compounding and masterbatch production. These characteristics contribute to improved manufacturing efficiency while enabling materials that meet higher durability requirements.

Extending Lifespan of Agricultural Films
In agricultural applications, plastic films must withstand intense sunlight, temperature fluctuations, and exposure to agrochemicals. BASF’s Tinuvin NOR platform provides stabilization solutions that extend the service life of mulch and greenhouse films.

Improved durability reduces material consumption and waste, supporting more efficient agricultural practices. The stabilizers also enable consistent mechanical and optical performance over extended periods, which is critical for crop protection and yield optimization.

The technology supports compliance with organic farming standards and aligns with broader sustainability objectives by reducing replacement frequency and associated environmental impact.




Stabilization for Rotomolding Applications
Rotomolded products, such as water storage tanks and industrial containers, require long-term resistance to environmental stress and chemical exposure. BASF’s Irgastab additive solutions are designed to enhance the durability of these materials, particularly in applications involving hazardous or sensitive contents.

The portfolio supports UV protection for up to 20 years, helping prevent material degradation during outdoor storage and transport across varying temperature conditions. In addition to durability, the additives contribute to improved processing efficiency, enabling more consistent production of large, hollow plastic components.

Lifecycle and Sustainability Considerations
The additive technologies are part of BASF’s broader VALERAS portfolio, which focuses on improving sustainability across the plastics value chain. By extending product lifespans and reducing material waste, these solutions contribute to lower lifecycle costs and reduced environmental impact.

Such developments are increasingly relevant in a digital supply chain, where material performance data and lifecycle tracking support more efficient resource use and compliance with environmental regulations.

Industry Context
The innovations presented at Chinaplas reflect ongoing efforts to improve the resilience and sustainability of plastic materials used in demanding environments. As industries seek to balance performance with environmental responsibility, advanced stabilizer systems play a key role in enabling longer-lasting and more reliable polymer applications across multiple sectors.
