From April 15–18, 2025, more than 4500 industry leaders and over 280,000 professionals gathered in Shenzhen for CHINAPLAS 2025, themed “Green + Smart.” As a global pioneer in anti-aging solutions for polymer materials, Rianlon showcased how innovation and circular-economy thinking can drive sustainability across the plastics sector through four immersive city-themed exhibits and four expert presentations.

Four City-Themed Scenarios: Showcasing Anti-Aging in Real-World Applications

As cities expand, material degradation increasingly impacts industries like construction, transportation, and renewable energy. Rianlon’s exhibit demonstrated practical anti-aging solutions across four urban applications:

Automotive & New Energy

Electronics & Appliances

Home & Apparel

Smart Agriculture & Building Materials

Through hands-on displays of antioxidants, light stabilizers, and tailored U-pack® formulations, Rianlon illustrated how these technologies extend material lifespans while reducing waste—critical for sustainable development.

Four Expert Presentations: Driving Insight and Innovation

1. New Energy Vehicles & Infrastructure

Under the twin drivers of the energy transition and intelligent mobility, new energy vehicles (NEVs), photovoltaics and energy-storage systems demand unprecedented weather resistance from their materials. Drawing on over 30 years of anti-aging expertise, Rianlon presented “Innovative Anti-Aging Solutions for Next-Generation NEV Plastics”, targeting the industry’s key challenges:

Battery systems & fast-charge components

For high-current, high-temperature operation:

U-pack® B7327

U-pack® B8119

Automotive interiors/exteriors & charging stations, cables and guns

For long-term outdoor weathering protection:

U-pack® B7327

U-pack® UV-7308

U-pack® UV-7303

U-pack® UV-703

Flame-retardant systems

Low-alkalinity, low-adsorption, high-temperature-resistant anti-aging packages

2. Engineering Plastics

In our talk “Dual-Track Weathering Technology: Ensuring Long-Term Reliability of Engineering Plastics”, Rianlon introduced a synergistic approach combining antioxidants and UV stabilizers to create a two-layer protection barrier. This technology is particularly effective in addressing the degradation of high-transparency PC materials, nylon, and TPU. Key application cases include:

High-transparency PC parts (e.g., headlamps, appliance housings)

Lower initial color, superior weathering:

RIASORB® UV-360UL

High-temperature PA & PC applications

Exceptional antioxidant performance and hydrolysis stability:

RIANOX® 686

TPU durability solutions

Long-life weather resistance:

U-pack® UV-7188

3. Smart Agriculture & Building Materials

As smart farming and urban development accelerate, materials must withstand harsher UV, temperature swings, and chemical exposure. In the report “Long-lasting Weathering Solutions: Protecting Agricultural Films Throughout Their Lifecycles”, Rianlon introduces a full-lifecycle solution framework tailors formulations to each application’s climate, thickness, and service life—ensuring reliable UV resistance, heat stability, and pesticide tolerance throughout the product’s lifespan while lowering overall production costs.

Application Highlights:

Fully Biodegradable Mulch Film – U-pack® UV-7612

By integrating anti-aging technology into a biodegradable matrix, this film supports healthy crop growth and then degrades harmlessly in the soil, minimizing environmental impact.

Smart Greenhouse Films – U-pack® UV-111 & U-pack® UV-7363

Engineered for greenhouse environments, these films deliver exceptional chemical resistance, extended service life, and superior light transmission—empowering precision growing in modern, automated greenhouses.

4. Circular Economy & Plastic Recycling

As the plastic recycling industry transforms globally, anti-aging technologies play a crucial role in solving the “quality degradation” problem in recycled plastics. Rianlon’s Technical Director, Henry Luo, unveiled “Innovative Anti-Aging Solutions for Recycled Plastics,” focusing on three critical stages:

Virgin-Material Design:

Integrating targeted stabilizers into new plastics to boost weather resistance and thermo-oxidative stability, extending service life and preventing waste at the source.

Recycling-Stream Enhancement:

Developing specialized anti-aging additive packages that restore mechanical strength, color integrity, and processability in recycled resins, shifting them from merely “recyclable” to truly “high-quality recyclable.”

High-Value Applications:

Combining anti-aging chemistry with modification processes so that recycled plastics meet the demanding standards of automotive interiors and electronic housings—unlocking premium reuse and higher material value.

Anchoring the Circular Economy with Anti-Aging

Rianlon believes anti-aging technology is the cornerstone of sustainable plastics. From boosting EV component life and engineering-plastic durability to protecting crop films and elevating recycled resin performance, we are writing the next chapter in “low-carbon, resource-efficient, high-quality” circular solutions. Moving forward, we will continue to deepen our anti-aging expertise and partner across the value chain—so that every gram of plastic contributes to a truly sustainable future.
